Expert Solution

Step 1

Humans have a closed type of circulatory system. It comprises a central pumping organ called the heart and its associated blood vessels. These blood vessels are responsible for providing blood to each and every tissue and organ of the body. The exchange of oxygenated blood and the removal of waste substances occurs at the level of capillaries and nearby tissues.
