Summary Introduction
Introduction:
Cardiovascular functioning is the functioning of the cardiac muscles that helps in the pumping of blood from heart to the rest of the body. The cardiovascular functioning is influenced by a variety of factors such as local factor, neural factors, endocrine factors and venous return
