9. 6.) 6.) The Lymphatic System – a system of transporting vessels designed to collect fluid & proteins that leak out of the capillaries and return them to the blood stream proper. ***(note – the “fluid collection” system of the body)
10. Fluid (mostly water) leaks out of the capillaries due to the high pressure within the blood vessels (arteries & capillaries). That fluid needs to be recovered and returned to the blood volume or it will build up in the tissue spaces. Muscle movements and the force produced by the heart “run” the lymphatic system. (***note – this is the lymphatic systems connection to the circulatory system)

12. Blood is the main transport medium of the body. It “carries” everything we need for life from one point in the body to another. Because of this, blood is considered the most important factor in maintaining homeostasis . Blood has dozens of “jobs” all tied to its transport function. We will list ten (10) of the most obvious & important. Can anyone name one?
13. 1.) Blood transports oxygen (O 2 ) from the lungs to the cells of the body . 2.) Blood transports carbon dioxide (CO 2 ) from the cells of the body to the lungs . 3.) Blood transports nutrients from the digestive tract to the cells of the body . 4.) Blood transports waste products from the cells of the body to the liver & kidneys .
14. 5.) Blood transports water (H 2 O) from the digestive tract to the cells of the body . 6.) Blood transports white blood cells & antibodies to fight infection . 7.) Blood transports platelets & fibrin to form clots which begins healing . 8.) Blood transports hormones from their production sites to target sites elsewhere in the body.
15. 9.) Blood transports heat from the muscles of the body to the surface of the skin & the lungs . 10.) Blood transports the body’s buffering system which allows the body to resist pH changes.
