The heart is made of four chambers which receive and pump blood. In the heart, the two circuits of the circulatory system (pulmonary and systemic circulation) converge. Before blood flows to the various parts of the body, it circulates in the heart and passes through the lungs. In this article, we will describe the path of blood through the heart and discuss the function of the heart as part of the circulatory system.
