Lower front portion of the heart, beneath the right atrium. Its wall thinner compared to the left ventricle. This is due to the lower pressure required to pump blood into the lungs versus rather than the entire body

Recieves deoxygenated blood from the right atrium and pump it into the pulmonary artery, which then carries the blood to the lungs for oxygenation

Located in the lower left portion of the organ. It has a thick, muscular wall, thicker than that of the right ventricle, due to the greater force required to pump blood throughout the entire body, as opposed to just the lungs.

Recieve oxygenated blood from the left atrium (via the mitral valve) and then pump it into systemic circulation through the aorta.

Arise from the ascending aorta immediately above the aortic valve. There are two primary coronary arteries: the left coronary artery and the right coronary artery.

Responsible for supplying oxygen-rich blood to the heart muscle. As the heart is continuously active and requires a constant energy supply, uninterrupted flow of oxygenated blood via the coronary arteries is essential for its proper functioning and survival.

A are the two upper chambers of the heart. The right atrium receives deoxygenated blood from the systemic circulation via the superior and inferior vena cava and the coronary sinus. The left atrium receives oxygenated blood from the lungs via the pulmonary veins. Both atria have a thinner muscular wall compared to the ventricles.

Right atrium is to collect deoxygenated blood returning from the body and funnel it into the right ventricle.

Left atrium's main role is to gather oxygenated blood from the lungs and direct it into the left ventricle

The atria, when they contract, ensure that the ventricles are filled adequately before the ventricles themselves contract.

Structure & Location

Function

Originates from the right ventricle of the heart. Then it divides into the left and right pulmonary arteries, which transport blood to the respective lungs.

Transport deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation, a process that's vital for the oxygen-carbon dioxide exchange in the lungs.

Thick wall and elastic - withstand the high pressure of blood being pumped from the heart + helps in maintaining continuous blood flow during diastole.

Ascending Aorta

Aortic arch

Thoraic Aorta

Abdominal Aorta

Distribute oxygenated blood from the left ventricle of the heart to the rest of the body, excluding the lungs

Starts from the left ventricle of the heart. It arches backwards and downwards to pass through the thorax and into the abdomen.
