Question

oxygenated blood delivered_____ml of blood to tissue during sternous exercise. ​

Answer 1

During exercise or under strenuous conditions, the muscle cells consume more oxygen. The partial pressure of oxygen in the tissue falls, as a result of which, the blood at the tissue level has only 4.4 ml of oxygen/100 ml of blood. Thus about 15 ml. of oxygen is transported by haemoglobin during exercise.

Answer 2

Answer:

Explanation:

Thus on an average 100 ml of blood carries about 20 ml (19.4 ml exactly) of O2 Hence under normal conditions, about 5 ml of oxygen is transported to tissues by 100 ml. of blood. During exercise or under strenuous conditions, the muscle cells consume more oxygen.
