Question

Q22) Which part of the heart:

a) Receives blood from the lungs

b) Pumps blood to the lungs

c) Pumps blood in to the body organs (except lungs)

d) Receives blood from the body parts​

Answer 1

Explanation:

The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides. On the right side of the heart, the right atrium and ventricle work to pump oxygen-poor blood to the lungs.
