1. Introduction to Organ Systems

2. Respiratory System
Lungs breathe in oxygen, and breathes out carbon dioxide from cells.
Uses blood vessels to
carry the O2 and CO2
between cells and lungs.

3. Circulatory System
Takes oxygen (from the lungs) and food nutrients to every cell in the body.
Removes carbon dioxide
and other cell waste.
Blood vessels are the highways
that end at every cell.

4. Nervous System
Brain and spinal cord relay messages to all parts of the body.
Controls all the major organs.
Allows for our five senses: Sight,
touch, hearing, smell and taste.

5. Digestive System Digests food nutrients into very small particles.
Small intestines absorbs the food nutrients into our blood vessels.
Blood vessels carry the nutrients to our cells.

6. Excretory System
Kidneys clean the blood, and turn the waste into urine.
Lungs get rid of carbon dioxide.

7. Muscular System
Muscles attach to our bones, to help move our skeleton.

8. Skeletal System Bones protect our organs, and help us stand upright.
Bones store calcium, and make blood.

9. Reproductive System The process that continues life on earth.
Hormones from the endocrine system help control male and female reproduction.

10. Immune System
A group of defenses that protects the body against disease-causing organisms.

11. Endocrine System A system of glands that uses hormones to control many
parts of your body.
Hormones are chemical
messengers that tell your body
to do certain things.

12. Skin Skin is the largest organ of your body.
Skin is the first defense against the outside world.
Sensory response- We feel our environment using nerves in our skin.

22. Blood travels through
the body and ends
up in a capillary!

24. Now the O2 gets
off, and the CO2
gets on!

to the lungs where
it gets breathed out!

31. Working Together
The Circulatory and Respiratory System work together to give Oxygen to all our body cells, and to get rid of Carbon Dioxide.
