PATHOLOGY

Detailed explanation-1: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart.

Detailed explanation-2: -Coronary veins are responsible for draining deoxygenated blood from the myocardium into the cardiac chambers. Comprised of two venous systems, coronary veins classify into either the greater cardiac venous system or the smaller cardiac venous system.

Detailed explanation-3: -There are two types of blood vessels, artery and veins. The artery is the blood vessels which carry the blood away from the heart towards the body parts. The arteries forms smaller and thinner capillaries which supply blood to the different organs in the body. The vein carry blood from body parts to heart.
