Understanding Pulmonary, Systemic, and Coronary Circulation

The circulatory system, also known as the cardiovascular system, is divided into three main parts: pulmonary, systemic, and coronary circulation. Pulmonary circulation involves the flow of blood from the heart to the lungs and back. Systemic circulation distributes blood throughout the body to major tissues and organs, excluding the lungs and heart, utilizing a vast network of blood vessels. Coronary circulation refers to the flow of blood and gases specifically to the heart.
