Choose all the answers that apply. oxygen is transported by blood picked up in the alveoli released into the air by the lungs pumped to cells by ventricles

The correct answer will be options-

1. transported by blood

2. picked up in the alveoli

3. pumped to cells by ventricles

Explanation:

Oxygen is an important element on earth on which life is dependent as it is the substrate of the important metabolic process of life.

The Oxygen in humans is inhaled and exhaled by breathing which when inhaled gets picked up or exchanged with the connective tissue of the body called blood in the alveoli of the lungs.

The oxygen in the blood is pumped to the body cells by the left ventricle of the heart which along with blood transports the oxygen by binding to haemoglobin in red blood cells.

Thus, the selected option is the correct answer.
