Question

C. The heart is an ever functioning pumping house. Trace the path of the two part pumping mechanism starting from blood flowing into the body cells.​

Answer 1

Answer:

The heart functions as a double ventricle. Blood moves from the body into the right atrium, and then into the right ventricle where it gets pumped into the lungs. Blood gets oxygenated in the lungs, moves into the left atrium, and into the left ventricle where it gets pumped into the body again.
