Cardiovascular system, also known as the circulatory system, is a body system that is responsible for pumping and distributing blood throughout the body. It is made up of the heart, blood vessels, and blood. Heart The heart is a muscular organ located in the chest that pumps blood throughout the body. It is about the size of a clenched fist and is located between the lungs, behind the breastbone. The heart has four chambers: the left and right atria, and the left and right ventricles. The right atrium is the upper chamber on the right side of the heart. It receives oxygen-depleted blood from the body and pumps it into the right ventricle through the tricuspid valve. The right ventricle is the lower chamber on the right side of the heart. It pumps the oxygen-depleted blood to the lungs through the pulmonary artery to be oxygenated. The left atrium is the upper chamber on the left side of the heart. It receives oxygenated blood from the lungs and pumps it into the left ventricle through the mitral valve. The left ventricle is the lower chamber on the left side of the heart. It pumps the oxygenated blood out to the rest of the body through the aorta, the main artery of the body. blood vessels Arteries are blood vessels that carry oxygenated blood away from the heart to the body's cells. They have thick walls and are able to withstand the high pressure of the blood being pumped from the heart. The aorta is the main artery of the body, and it branches off into smaller arteries that carry blood to the head, arms, legs, and other parts of the body. Veins are blood vessels that carry oxygen-depleted blood back to the heart. They have thinner walls than arteries and are not able to withstand as much pressure. The superior and inferior vena cava are the main veins of the body, and they carry blood from the head, arms, and upper body to the heart. #biology #medical #science #anatomy #muscles #cardiacmuscles #cardiology #heart #heartmuscles #blood #cardiovascularsystem
