Blood Composition and Key Roles Blood is composed of plasma and formed elements, each serving distinct functions. Oxygenated blood returns via pulmonary veins to the left atrium.
Understanding Blood Flow Through the Cardiovascular System
Core Components and Function At the center of the system is the heart, a muscular pump that rhythmically contracts to propel blood. Nutrients and oxygen diffuse into tissues.
Deoxygenated blood collects in veins and returns to the right atrium. Red blood cells transport oxygen, white blood cells defend against infection, and platelets enable clotting.
