What circulatory system is divided into two main parts the circulation and the pulmonary circulation.?

The circulatory system consists of two main components: systemic circulation and pulmonary circulation. Systemic circulation is responsible for delivering oxygenated blood from the heart to the rest of the body and returning deoxygenated blood back to the heart. In contrast, pulmonary circulation carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart. Together, these two systems ensure efficient blood flow and gas exchange throughout the body.
