The pulmonary circuit moves deoxygenated blood to the lungs for oxygenation and then returns oxygen-rich blood to the heart. Oxygenated blood returns via pulmonary veins to the left atrium.
Heart Muscle Rhythm Contraction Fundamentals
Core Components and Function At the center of the system is the heart, a muscular pump that rhythmically contracts to propel blood. Systemic Circuit Pathway Left ventricle pumps oxygenated blood into the aorta.
The cardiovascular system operates as the body’s relentless transport network, delivering oxygen and nutrients to tissues while removing metabolic waste. Deoxygenated blood collects in veins and returns to the right atrium.
Heart Muscular Pump Rhythm Contraction Basics
Blood travels through capillaries in the lungs. Recognizing how each element of the cardiovascular system contributes to overall function highlights the importance of maintaining vascular health.
