PATHOLOGY

Detailed explanation-1: -Your pulmonary veins, superior vena cava and inferior vena cava (veins) carry blood into your 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: -The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium). The superior vena cava carries blood from the brain and arms into the top of the right atrium.
