Cardio

Superior vena cava coursing towards the right atrium of the heart, returning deoxygenated blood from the body. The SVC is one of the 2 large veins by which blood is returned from the body to the right side of the heart.

The aorta is the main artery that carries blood away from your heart to the rest of your body. After the blood leaves the heart through the aortic valve, it travels through the aorta, making a cane-shaped curve that connects with other major arteries to deliver oxygen-rich blood to the brain, muscles, and other cells.

The pulmonary arteries and the pulmonary veins are the vessels of the pulmonary circulation; which means they are responsible for carrying the oxygenated blood to the heart from the lungs and carrying the deoxygenated blood from the heart to the lungs

The right atrium is the first chamber of the heart to receive deoxygenated and carbon dioxide-rich systemic blood from the body, and the left atrium is the first chamber to receive the oxygenated blood returning from the lungs.

The pulmonary valve normally acts like a one-way door from your heart's right ventricle to the lungs. Blood flows from the right ventricle through the pulmonary valve to the pulmonary artery and then into the lungs, where it picks up oxygen to deliver to your body.

Your mitral valve is located between the left atrium and left ventricle of your heart. It regulates the flow of blood from your lungs into the left ventricle, the main pumping chamber.

The tricuspid valve helps keep blood flowing in the right direction through the heart. It separates one of the heart's two upper and lower chambers (atria and ventricles).

The aortic valve is a sophisticated structure that performs a range of functions resulting in the unidirectional flow of blood out of the left ventricle, the optimising of coronary blood flow, and preservation of myocardial function.

The inferior vena cava is ultimately responsible for the transport of almost all venous blood (deoxygenated) from the abdomen and lower extremities back to the right side of the heart for oxygenation.

The left ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.
