The right ventricle pumps blood to the a.body b.lung while the left ventricle pumps blood to the a.body b.lung

The correct answer is option 1. blank - b. lung. and 2. blank - a. body.

Explanation:

In the heart, there are four chambers that play a different role in the circulation of the oxygenated blood into the body from the lungs and deoxygenated blood to the lungs from different parts of the body.

The right ventricle is the cardiac chamber that pumps the deoxygenated blood to the lungs to carry oxygen. Atria of the left side gets the oxygenated blood from the lungs and push or pump it to the left ventricle. The left ventricle pump this blood to the distinct parts of the body.

Thus, the correct answer is - option 1. blank - b. lung. and 2. blank - a. body.
