Answer:
- pumped to cells by ventricles
- picked up in the alveoli
- transported by blood
Explanation:
Oxygen is very important to human beings as it supplies our means of making energy through respiration. Oxygen is transported by blood through the arteries to the rest of the body.
Oxygen is picked up by blood at the alveoli which are sort of like air sacs in the lungs that take in oxygen when the body breathes in.
The oxygen-rich blood then comes into the heart through the left atrium which then sends it to the left ventricle. The Left ventricle then pumps blood to the rest of the body (cells).
