While hormones and signals from the brain adjust the rate of contraction, cardiac muscle stimulates itself to contract.
The heart is a muscle that pumps blood throughout your body. The blood carries oxygen and nutrients that your body needs to work correctly.he function of the heart is simple. It keeps blood circulating throughout the body by: 1  Pumping blood through your lungs to make certain that the blood supply is constantly refreshed with oxygen and carbon dioxide is removed, and. 2  Pumping blood through your body to meet its demand for oxygen and nutrients.
