Expert Solution

Step 1

The circulatory system consists of three systems that work together; the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The circulatory system is responsible for carrying and supplying oxygen, nutrients, and hormones to the cells, and to remove cell waste and carbon dioxide from the cells.

The heart is a muscular organ, which pumps blood through the blood vessels to the different organ tissues.
