The systemic circuit transports oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart. The sinoatrial node acts as a natural pacemaker, setting the rhythm.
Simple Cardiovascular System Function Guide
This intricate system relies on the heart, blood, and blood vessels to maintain homeostasis and support cellular function. Recognizing how each element of the cardiovascular system contributes to overall function highlights the importance of maintaining vascular health.
Systemic and Pulmonary Circulation Two primary circuits enable continuous flow throughout the body. The pulmonary circuit moves deoxygenated blood to the lungs for oxygenation and then returns oxygen-rich blood to the heart.
Simple Cardiovascular System Function Guide
Veins contain valves that prevent backflow and rely on muscle contractions to return blood to the heart. Arteries branch into smaller arterioles and capillaries.
