Cells
Basic units of structure and function in living things.
Cells
Tissues
An integrated group of cells with a common function, structure, or both.
Tissues
Organs
A combination of tissues designed to perform a specific function or several functions or jobs.
Organs
Organ Systems
A group of organs that work together to perform a specific function or job.
Organ Systems
Muscular System Function
Moves limbs and trunk; moves substances through body; provides structure and support
Muscular System Function
Digestive System Function and Main Organs
Breaks down, extracts and absorbs nutrients from food, removes wastes, maintains water and chemical balances
Main Organs: mouth, esophogus, stomach, intestines
Digestive System Function and Main Organs
Excretory System Function and Main Organs
Removes wastes from blood; regulates concentration of body fluids.
Main Organs: Kidneys, bladder, lungs
Excretory System Function and Main Organs
Respiratory System Function and Main Organs
Takes in oxygen for cells and releases carbon dioxide as waste.
Main Organs: Lungs, nose, mouth, trachea/windpipe
Respiratory System Function and Main Organs
Circulatory System Function and Main Organs
Delivers oxygen and nutrients to body cells and transports waste products to excretory organs.
Main Organs: heart, veins, arteries, capillaries
Circulatory System Function and Main Organs
Nervous System Function and Main Organs
Regulates behavior, maintains homeostasis; regulates other organ systems; controls sensory and motor functions
Main Organs:Brain, Spinal cord, nerves and special sense organs such as eyes and ears.
Nervous System Function and Main Organs
1) The Circulatory System: The heart is a muscle that pumps blood.
2) The Digestive System in several places.
-The muscles of the jaw help to chew food
-The muscles that line the esophagus move food from the mouth to the stomach.
-Muscles lining the intestines move digesting food along
3) The Respiratory System is the diaphragm: a large, flat muscle that is in between the lungs and the intestines. It is the movement of the diaphragm that causes the lungs to inflate and deflate.
Muscular System Interacts With…
The digestive system works very closely with the circulatory system to get the absorbed nutrients distributed throughout your body.
Digestive System Interacts With…
1) Your nervous system interacts with every other system in your body. All of your tissues and organs require instruction and direction from the nervous system.
2) Muscular system and nervous helps you move around and interact with your environment.
3) Your digestive and excretory systems work with the nervous system in both conscious ( and unconscious . While digestion goes on without your thoughts, eating, peeing, and pooping are under your control.
Nervous System Interacts With…
1) The circulatory system: The lungs are where the oxygen is picked up by the blood and then transported around the body
2) Nervous System: It controls the breathing rate
Respiratory System Interacts With…
The excretory system is a close partner with the circulatory system. Blood that circulates through the body passes through one of the two kidneys. Urea, uric acid, and water are removed from the blood and most of the water is put back into the system.fgrrgbh
Excretory System Interacts With…
1) The circulatory system works closely with ALL other systems in our bodies. It supplies oxygen and nutrients to our body systems by working with the respiratory system.
2) At the same time, the circulatory system helps carry waste and carbon dioxide out of the body.
3) The Digestive System brings in food and turns it into nutrients. The Circulatory system helps get the nutrients into cells.
3) The excretory system removes wastes and balances the water in our blood . The circulatory system helps it get the wastes out (urine) or recycles them (water)
Circulatory System Interacts With…
1) Organ System (MOST COMPLEX))
2) Organ
3) Tissue
4) Cell
5) Organelles (BASIC)
