is a collection of veins joined together to form a large vessel that collects blood from the myocardium of the heart. It is present in humans and other animals.
It receives blood mainly from the small, middle, great and oblique cardiac veins. It also receives blood from the left marginal vein and the left posterior ventricular vein. The anterior cardiac veins drain directly into the right atrium. (Some small veins drain into any of the four chambers of the heart.) It drains into the right atrium on the posterior, inferior surface, medial to the inferior vena cava opening.
The coronary artery
The coronary circulation provides blood to the heart's tissues. The coronary circulation includes the coronary arteries and coronary veins.
Baroreceptors regulate the blood pressure of all vertebrae and are located in the blood vessels. It is a type of mechanoreceptor which is excited when a blood vessel is stretched.
Veins are the type of blood vessel that drains blood from tissues and returns it to the heart.
