|Description of Exhalation
|Diaphragm and muscles between the ribs relax (loosen) (Pushes air out) – Chest contracts
|How does oxygen get into the cells of the body?
|Oxygen is diffused through the alveoli into the blood stream (inhaled air) and Carbon Dioxide is diffused out of the blood stream (exhale air)
|What is respiration?
|The rate of oxygen and carbon dioxide moving in and out of the body
|tiny sacs of lung tissue specialized for the movement of gases between air and blood
|Tiny blood vessels that connect the smallest arteries with the smallest veins. Oxygen and carbon dioxide are exchanges here.
|Name the organs in the Respiratory System (8)
|Nose/Mouth –> Epiglottis –> Pharynx and Larynx –> Trachea –> Bronchi –> Bronchioles –> Alveoli
|Tube-like passage way used by air, food and water.
|Flap of skin at the lower end of the pharynx that covers the trachea during swallowing so food or water does not enter the lungs
|Air conducting tube that connects the pharynx with the bronchi
|Two short tubes at the end of the trachea that carry oxygen to the lungs (two lungs)
|Tiny branches of air tubes in the lungs that carry oxygen from the bronchi to the alveoli
|Thing grape-like clusters at the end of bronchioles, covered in capillaries. This is where oxygen and carbon dioxide are exchanged in the blood.
|System that circulates/moves blood throughout the body
|Describe the path of blood in the body
|From Body -> Right Atrium -> Right Ventricle -> Lungs then from Lungs -> Left Atrium -> Left Ventricle -> Body
|Red Blood Cells
|Transfers oxygen and nutrients to parts of the body and removes waste.
|Helps a wound close up by clotting
|White Blood Cells
|Helps the body defend itself by protecting against infection and disease by discovering and fighting germs
|Blood vessel that returns blood to the heart. The color of this blood is blue and contains carbon dioxide and wastes.
|Sheet of muscles across the bottom of chest cavity that causes us to inhale and exhale
|Blood vessel that carries blood away from the heart. This blood is red and is rich with oxygen and nutrients.
|A larger more muscular chamber of the heart that pumps blood through the body.
|Closed Circulatory System
|Blood stays within the heart or blood vessels
|Open Circulatory System
|Blood does not stay within the vessels at all times
|What controls the direction of the blood flow in the veins and arteries and heart?
|This system eliminates waste from the body
|Name organs in the excretory system
|Skin, Lungs, Large Intestine, Liver, Kidneys
|What organs are included in the urinary system (4)?
|Kidneys, Ureters, Urinary Bladder and Urethra
|Filters blood and produces urine
|Transports urine from kidneys to urinary bladder
|Transports urine out of the body

|muscular J shaped organ that has a mucus lining to protect it from the acid
|What is the Endocrine System?
|The system that uses chemical messages (hormones) to control the body
|Name the major glands within the endocrine system (10)
|1. Hypothalmus, 2. Pituitary Gland, 3. Pineal Gland, 4. THyroid Gland, 5. Parathyroid Gland, 6. Thymus, 7. Adrenal Gland, 8. Pancreas, 10. Ovary or Testis
|What does the Pituitary Gland do?
|The master gland that coordinates the work of other glands
|What does the Thyroid Gland do?
|Keeps calcium level in the blood from rising too high and manages metabolism
|What does the Adrenal gland do?
|What does the Pancreas do?
|Makes insulin to manage glucose in the blood.
|What are the two response (regulatory) systems of the body?
|1. Nervous System and 2. Endocrine System
|What is the Nervous System?
|The system that transmits signals between different parts of the body.
|What pathways and organs does the nervous system use (3)?
|1. Brain, 2. Nerves, 3. Sensory Organs (nose, eyes, skin, ears, tongue, proprioception)
|What stimuli does the nose detect?
|Smell / odours – airborne chemicals
|What stimuli do the eyes detect?
|What stimuli do the ears detect?
|What stimuli does the tongue detect?
|What is proprioception?
|The ability to detect where your body parts are located without looking at the part.
|What are nerves?
|Fibre bundles throughout the body that transmits messages from the brain
|What is the Immune System?
|Three lines of defense to protect the body from invading organisms: 1. Barriers, 2. White Blood Cells and 3. Antibodies
|Name four examples of a barrier line of defence? What are their purpose?
|Skin, Hair, Nails, Mucus
They prevent invaders from entering the body.
|How do white blood cells defend the body (2 points)?
|1. Move towards the damaged tissue or invaders
2. Engulfs and destroys the damaged tissue or invader
|What are antibodies?
|Y-shaped proteins produced by special white blood cells .
|What is an infection?
|The invasion of a host organism by another organism that will live on or in the host.
|Two examples of infectious organisms?
|What is bacteria (3 points)?
|Eat cells and tissue
Creates toxins (poison)
|What is a fungal infection?
|Fungi releases enzymes that break down cells and tissues, then they absorb the nutrients.
|What is a protist infection?
|Grow on or in an orgams, they will eat the host cells.
Transmitted by ingesting infected food or water or through other organisms like fleas, ticks, mosquitos.
|What is a viral infection?
|Organisms made from genetic materials (DNA) and a protein coat. Invade cells by injecting their genetic material into the host cell which will then produce more viruses. The viruses rupture the host cells and release new viruses to invade more cells.
|Go to this website and add www to label the heart diagram
|What are valves?
|One-way doors found on the sides of the human heart. They keep blood flowing in one direction in the heart.
