How many chambers are in our hearts, and what is the working system of each chamber?
The human heart has four chambers: two atria and two ventricles. The working system of each chamber is as follows:
Right Atrium: The right atrium receives deoxygenated blood from the body through the superior and inferior vena cava. The blood then flows through the tricuspid valve into the right ventricle.
Right Ventricle: The right ventricle pumps the deoxygenated blood received from the right atrium through the pulmonary valve and into the pulmonary artery, which carries the blood to the lungs for oxygenation.
Left Atrium: The left atrium receives oxygenated blood from the lungs through the pulmonary veins. The blood then flows through the mitral valve into the left ventricle.
Left Ventricle: The left ventricle pumps the oxygenated blood received from the left atrium through the aortic valve and into the aorta, which carries the blood to the rest of the body.
The heart works as a pump, contracting and relaxing in a rhythmic pattern to circulate blood throughout the body. The right side of the heart pumps de- oxygenated blood to the lungs for oxygenation, while the left side pumps oxygenated blood to the rest of the body. The coordinated contraction and relaxation of the four chambers is critical for the proper functioning of the cardiovascular system.
