Vertebrae Circulation |
1. closed circulatory system composed of blood vessels + 2 or 4 chamber heart 2. capillary bed 3. in a cell (mitochondria) 4. use of O2 |
|
|
Blood Vessels |
1. arteries 2. veins |
|
|
Arteries |
1. transport blood 2. high O2 3. low CO2 4. flows to capillary beds |
|
|
Veins |
1. transport blood 2. high CO2 3. low O2 4. flows away from capillary bed |
|
|
Capillary Beds |
1. the sites of chemical exchange between blood + interstitial fluid 2. occur throughout the body |
|
|
Interstitial Space |
space between cells filled with fluid |
|
|
Capillary |
1. small wall 2. thin diameter |
|

Circulation In The 4 Chambered Heart |
1. 4 chambers 2. process 3. process repeats |
|
|
4 Chambers |
1. Left Atrium (chambers) 2. Left Ventricle (muscular) 3. Right Atrium (chambers) 4. Right Ventricle (muscular) |
|
|
Process |
1. Right Ventricle a. pumps blood to the lungs where O2 is loaded and CO2 is unloaded 2. Oxygen-rich blood from the lungs a. enters the heart at the left atrium b. blood flows from the left atrium to the left ventricle c. left ventricle contracts, pumps O2 blood to various parts of the body |
