Closed Circulatory System - Advantages
A
- Higher pressures = increased efficiency for meeting high metabolic demand
5
Q
Describes the human CV System - ppt 꼭보세용..
A
- Starting from the Right atrium, the right ventricle pumps the blood to the lung via
- the pulmonary artery,
- In the lung occurs gas exchanges via capillaries in both the right lung and left lung (blue: deoxygenated -> red: oxygenated)
- Then the blood goes back to the Left atrium via the Pulmonary vein 5. The left ventricle pumps blood via the Aorta
- To the brain and legs; gas exchanges occur at capillaries of the head and forelimbs and capillaries of abdominal organs and hind limbs (Red -> Blue)
- the blood from the head and leg goes back to the Right atrium
