Answer 1

Answer:

The structure of the heart

The heart is a large muscular pump and is divided into two halves - the right-hand side and the left-hand side. The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs. The left-hand side pumps oxygenated blood around the body.
