Health Conditions Associated With The Circulatory System Biology Essay

Human existences are portion of the life things which is good organized. The Cells in the human organic structure signifiers tissues and such tissue is good organized to organize the assorted variety meats. These variety meats include the digestive system, respiratory, elimination, circulatory system, skeletal system muscular systems. The circulatory system is of import as portion of the circulation procedure among the variety meats. The circulatory systems enable the human organic structure to be make fulling with the blood which serves legion maps as transit, regulative and protection. This paper will nevertheless research the human anatomy and physiology of how the human organic structure maps. It will nevertheless exemplify a diagram of the circulatory system and disease associated with the circulatory system its cause and ways of forestalling such disease.

Harmonizing to Sandhyarani ( 2000 ) “ the circulatory systems are indispensable for the organic structure since it is responsible for providing foods and O to the organic structure cells and tissue ” ( p.237 ) . In a sense, “ The circulatory system is the conveyance system, that supplies substance absorbed from the GI piece of land O ( O2 ) to the tissues, returns C dioxide ( CO2 ) to the lungs and other merchandises of metamorphosis to the kidneys, maps in the ordinance of organic structure temperature, and distributes endocrines and other agents that regulate cell map ” . ( Ganong, F. William, 1973, p. 379-390 ) . The blood serves as a legion maps which help in free flow of circulation throughout the vas and back to the bosom. The blood begins to go around as its moves the bosom from the left ventricle and so goes to the aorta. The aorta is really big arteria in the human organic structure nevertheless the blood leaves the aorta with full O so the cells in the encephalon and the organic structure starts to work. The O blood circulates in the organic structure and its system of arterias into the smallest arteriolas back to the bosom, the blood travels into the venas as its reaches the lungs, metabolic substances such as C dioxide or waste merchandises are removed from the blood and so fresh O will is replaced enables the human organic structure to be inhaled as its base on ballss through the lungs. The circulatory system is responsible for the free flow of blood into the organic structure. However it is besides responsible for transporting foods, H2O, O, into the whole organic structure cells. Secretion substance and metabolic waste are acquire rid off due to the circulatory system. The major constituent of the circulatory systems are divided into two which consist of cardiovascular system which is t the bosom, blood vass, and lymphatic system which consists of the lymph vass, lymph nodes and lymphoid variety meats. ( Van De Graaff and Fox, 1985, p.549 ) .

Van De Graaff and Fox in 1985 stipulate that, “ the paths of the circulatory blood flow consist of the systematic and pneumonic circulation. The pneumonic circulation are made up of the blood vass that transport blood from the right ventricle to the lungs for gas exchange and so to the left atrium of the bosom. It includes the pneumonic bole with its semi lunar valve, the pneumonic arterias that transport blood to the lungs, the pneumonic capillaries within each lung, and four pulmonary venas that transport oxygenated blood to the bosom. On the other manus, the systematic circulation is composed of all the staying vass of the organic structure that are non portion of the pneumonic circulation. It includes the aorta with its semi lunar valve, all of the subdivisions of the aorta, all capillaries other than those in the lungs, and all veins other than the pneumonic venas. The right atrium receives all the venous return of oxygen-depleted blood from the systemic venas ” ( Van De Graaff and Fox p.549 ) .

Circulatory system

The Circulatory System which includes the Heart, the Blood and the Blood Vessels

The Functions of the Circulatory System associating to the Organs

The circulatory system is an indispensable system for the circulation of blood into the organic structure. The blood nevertheless can function as an agent of transporting diseases which can do virus, bacteriums and toxic. The circulatory system serves as a protective usher with aid of the white blood cells and lymphatic system. For the circulatory systems to work efficaciously, the system works together with other variety meats to do free flow of circulation. The maps of the circulative systems can be categorized into three countries viz. transit, ordinance and protection.

Transportation system

Transportation system is a manner of transporting substances into the organic structure. The assorted substance of the cellular metamorphosis is transported by the circulatory systems. These substances are respiratory, digestive, excretive, endocrinal, and skeletal systems.

Respiratory, the ruddy blood cells, or erythrocytes transport O to the tissue cells. In the lungs, O from the inhaled air attaches to hemoglobin molecules within the red blood cells and is transported to the cells for aerophilic respiration. Carbon dioxide produced by cell respiration is carried by the blood to the lungs for riddance in the exhaled air. . ( Van De Graaff and Fox, 1985, p.549 ) . Besides, the digestive system is antiphonal for the dislocation of nutrient so that it can be absorbed through the enteric wall and into the blood vass of the circulatory system. The blood so carries these captive merchandises of digestion through the liver and to the cells of the organic structure. Another organ is the excretory system ; metabolic wastes, inordinate H2O and ions every bit good as other molecules in plasma ( the fluid part of blood ) are filtered through the capillaries of the kidney and excreted in piss. Furthermore with the Muscular system, the blood vass deliver foods and O to musculuss, carry off wastes. Muscles contraction keeps blood traveling in the bosom and blood vass. Again under the skeletal systems, the blood vass deliver foods and O to castanetss ; transport away wastes. Rip coop protects bosom ; ruddy bone marrow produces blood cells, castanetss store Ca2+ for blood vesture. Nevertheless, the nervous system helps the blood vas to present foods and O to neutrons ; transport away wastes. Brain controls nervousnesss that regulate the bosom and dilation of blood vass.

Last the hormone system, here the blood vass transport endocrines from secretory organs ; blood services glands ; bosom produces Atrial Natriuretic endocrine. Epinephrine increases blood force per unit area ; ADH, Aidosterone, and Atrial Natriuretic endocrine factors help regulates blood volume ; growing factors control blood cell formations. ( Mander, S. 2002, p. 125- 143 ) Regulation

Another map of the circulatory system is the ordinance that is, the blood carries endocrines and other regulative molecules from their site of beginning to distant mark issues. Diversion of blood from deeper vass to come up vass in the tegument AIDSs in the ordinance of organic structure temperature.


The circulatory system protects against hurt and foreign bugs or toxins introduced into the organic structure. The vesture mechanism protects against blood loss when vass are damaged, immune to many disease-causing agents. Leukocytes may besides protect the organic structure through phagocytosis ( Van De Graaff and Fox, 1985, p.549 ) .

Health Condition Disease Associated with the Circulatory System

The human organic structure needs a healthy system in order to last. When an person is fit and strong the circulatory system works together with other system for all the organic structure. The circulatory system enables foods and O into the cells and tissue. When the human bosom round, blood circulates by transporting into the blood vass to enable the food to travel through every parts of the organic structure. Sandhyarani ( 2000 ) assert that However since the circulatory system consist of the blood, bosom and blood vass there are sort of disease associated with it. The blood which serves as a legion maps in the organic structure consist of the ruddy blood cell and white blood cells, thrombocytes and blood plasma the blood vass besides contains the capillaries, arteriolas, and venas, nevertheless all these constituents of the circulative systems makes it work efficaciously, any upset that may impact these constituents might consequences in complication and disease that can stop or do decease to the human organic structure.

In today ‘s universe, the rate of circulatory or cardiovascular ( CVD ) disease is on high rate doing prematurely decease in the western and the low in-between income states. The CVD is a taking mortality with 82 % of people deceasing in the low in-between states particularly Ghana. Modern research workers have nevertheless dealt into the causes and ways in showing the disease. An person can develop the circulatory system job at nowadays at birth. The following are the disease associated with it.

Aortal Aneurysm

Harmonizing to Mader ( 2002 ) an “ aneurism is a ballooning of a blood vass, most frequently the abdominal arteria or the arterias taking to the encephalon ” . ( p. 137 ) . Disease such as coronary artery disease, high blood pressure, fleshiness and high blood force per unit area can do the aneurism that is the wall of the arteria can be weakened or desert. The aortal is the largest arteria in the organic structure and it is really likely to do decease if its explosion. However when damaged it can be replaced with a fictile tubing.

Angina or Myocardial Infarction ( IM )

A myocardial infarction is besides called the bosom onslaught, this disease of the circulatory system occur as a consequence of the obstruction in the blood vass taking to the bosom, this can wholly kills the bosom musculuss due to miss of O, when the coronary arteria is blocked, the arm develop a radiating hurting in the left arm. Nitroglycerin drugs normally help to alleviate the hurting. Any obstruction of the coronary arteria wholly, in a manner of the Thrombeombolism, a bosom onslaught has occurred.

Cerebrovascular Accident, ( CVA )

A Cerebrovascular can be called shot, shots consequences when a little cranial arteriole explosion or is blocked by an embolus ” when the human encephalon deficiencies oxygen it can do the encephalon to decease and palsy and even decease of a individual. When an single nevertheless experience the symptoms such as feeling of numbness in the custodies, or face trouble in speech production and impermanent sightlessness, such individual must instantly speak to a medical physician for reding. Sandhyarani ( 2000 ) .

High blood pressure

Harmonizing to Jones et Al ( 1978 ) , “ Hypertension merely means high arterial blood force per unit area ” ( p.344 ) . It is estimated that 20 % of Americans are enduring from high blood pressure which is the high blood force per unit area. In Ghana, from the past 30 old ages, the rate of high blood pressure has increased drastically which is a now a populace job. High blood pressure can do decease at the center in males. Hypertension nevertheless, is a status at present when the systolic blood force per unit area is 140 or greater or the diastolic force per unit area is 90 or greater. Both systolic and diastolic is in of import when it comes to interventions. Hypertension is a silence slayer disease because of its late sensing. This consequence of two familial factors such as Angiotensinogen and plasma that is converted to a powerful vasoconstrictive in portion by the merchandise of the 2nd cistron. High blood pressure can be cured if a patient goes to regular cistron therapy.


Harmonizing to Mader ( 2002 ) “ coronary artery disease is an accretion of soft multitudes of fatty stuffs, peculiarly cholesterin, beneath the interior liners of arterias ” ( p.137 ) . The sedimentation is called plaque. The plaque interrupts with the lms of the vass and so turns to barricade the free flow of blood. The coronary artery disease can be inherited in some households. Early sensings of the disease can be cured or prevented from distributing. Atherosclerosis can get down at early maturity to the in-between age but it ‘s hard to observe the symptoms early about around 50 or order. To forestall means one must goes through intensive dietetic procedure or one return less cholesterin.

The Causes and Ways of Preventing the Disease of the Circulatory System

In the past 20 old ages, research worker has come out with ways and bar of disease refering to the circulatory system. Most doctors have studied to now hold cognition about the hazard factor and are able to observe the illness earlier. Some of the hazard factors of the circulatory system are high blood pressure, fleshiness, and smoke. Harmonizing to Van De Graaff and Fox in 198 suggested that, the circulatory system can be under functional if the person is found smoke, drug maltreatment and weight addition and other.


Jones EL at in 1978 stipulated that, Tobacco contains more than 100 chemical compounds and out of that 270 chemicals can be identified in the coffin nail fume. Smoke can be a wont person enjoys making without looking frontward to see the causes of how the coffin nail can damage the blood stream. Persons who smoke destruct the bosom. Nicotine causes the arteriolas for the blood force per unit area to lift such limitation block the easy circulation of blood. Under more serious note, the bosom demand to pump the blood harder through the lungs at a clip nevertheless when the O transporting capacity of the blood is reduced, so consequences in cardiovascular upset. The usage of the baccy can do lung malignant neoplastic disease because of the inhales and malignant neoplastic disease of the lingua, lips, and larynx. Again respiratory disease such as bronchitis and emphysema can ensue when smoke.

Drugs Abuse

Drug maltreatment is any inordinate usage drugs which is non prescribed by qualified medical physicians nevertheless stimulations, drugs like cocaine, heroine and pep pill is really unsafe to an single wellness. The stimulations drugs can consequences in upnormal bosom round which can do bosom onslaught which can finally take to decease. Intravenous drugs an consequences in intellectual blood coagulum and shot. Harmonizing to research excessively much intoxicant can damage the variety meats including the bosom.

Weight Gain

A individual with heavy weight that is 20 % heavy above the normal weight in tallness is more likely to acquire high blood pressure ( high blood force per unit area ) . Most tissue requires serving and the bosom sends the excess blood out under greater force per unit area in those who are overweight. Harmonizing to Jones EL at 1978 “ An corpulent individual with high blood force per unit area ( high blood pressure ) runs a greater hazards of coronary bosom disease than does a nonobese individual with high blood pressure ” ( p. 286 ) . Research workers have stipulated that, it may be harder to lose weight once it is gained, and therefore it is recommended that weight control be a womb-to-tomb enterprise ; even a little lessening in weight can convey with it a decrease in high blood pressure.

Personality Trait

Personality trait has been scientifically proved that, males are more likely to contract bosom onslaught at an early age than adult females. It is nevertheless concluded that adult females who are in their climacteric are likely to acquire shot or bosom onslaught.

Jones et Al ( 1978 ) suggested that, the hazard factors of the circulatory diseases can be controlled or eliminated through regular medical medical examination. An single agony from high blood pressure can be recommended by a medical physician in the ways of commanding the high blood force per unit area particularly a household with a history of high blood force per unit area. Furthermore, an corpulent people should eat less nutrient and cut down an consumption of high Calories and fatty nutrient by altering your eating wont. Furthermore, smoke of baccy shortens lives hence single that are found smoke must halt. Coffee is a stimulating drug which should non be taken as drink in the forenoon. Last, regular exercising helps easy flow of blood throughout the circulatory system. However, medical physicians encourage patients to look into their pulse whilst exercise.


The circulative disease can be treated depending on how serious or critical the instance of conditions is. Surgery or bosom graft can be done when a individual is affected with cardiovascular disease. However early sensings saves lives. Nevertheless, persons are advice to let airing in enclosed topographic points such their suites, workplaces and churches. Persons should avoid traveling near tobacco users or chemical compounds that can impact their lungs in order to reconstruct external respiration and maintain circulation.
