Blood Flow in Heart, Blood Flow through Heart || Cardiovascular System in Hindi
The human heart, a marvel of anatomy, drives the intricate process of blood flow and circulation throughout the body. Within its chambers, blood journeys through a meticulously orchestrated pathway, delivering oxygen and nutrients while removing waste products. This journey begins with deoxygenated blood entering the right atrium from the body's veins, passing through the tricuspid valve into the right ventricle. As the heart contracts, blood is propelled through the pulmonary valve into the pulmonary artery, making its way to the lungs for oxygenation. Oxygen-rich blood returns to the heart via the pulmonary veins, entering the left atrium and flowing through the mitral valve into the left ventricle. Once more, the heart contracts, sending oxygenated blood through the aortic valve into the aorta, from which it is distributed throughout the body's arteries. This continuous cycle of contraction and relaxation ensures the body's vitality, demonstrating the remarkable efficiency and precision of the heart's function in sustaining blood flow and maintaining overall health.
