MICROANATOMY

Detailed explanation-1: -Your blood is pumped around your body through a network of blood vessels: arteries – they carry oxygen-rich blood from your heart to all parts of your body, getting smaller as they get further away from the heart.

Detailed explanation-2: -The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

Detailed explanation-3: -The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
