Answer: E- The right ventricle.
Explanation: Deoxygenated blood with carbon dioxide and metabolic products collected from the tissues by the capillaries returns to the heart via the venous system and enters the right atrium of the heart. It is then pumped to the right ventricle, then transported to the lungs via the pulmonary artery for gaseous exchange, where oxygen is collected and carbon dioxide is dropped off.
Answer:
increase
Explanation:
As water and ions are lost through exercise, overall blood volume can decrease. To maintain adequate blood volume and blood pressure, renin is secreted to help in the conversion of angiotensin I to angiotensin II. This will cause vessels to constrict and sodium and water to be retained by the kidneys.
Because facilitated diffusion is a passive process, it does not require energy expenditure by the cell. Water also can move freely across the cell membrane of all cells, either through protein channels or by slipping between the lipid tails of the membrane itself.
hope this is the right answer......
