Question

at the venous end of tissue capillaries, there is no net movement of o₂ and co₂. true or false true false

Explanation:

At the venous end of tissue capillaries, there is still a net movement of \(O_2\) and \(CO_2\). Oxygen diffuses from the blood (lower \(O_2\) concentration at venous end compared to arterial end but still higher than in some tissues in active metabolism) to the tissues (higher \(O_2\) demand in some cases), and \(CO_2\) diffuses from the tissues (higher \(CO_2\) concentration due to cellular respiration) to the blood.

Answer:

False
