What is the coronary circulation?

coronary circulation, part of the systemic circulatory system that supplies blood to and provides drainage from the tissues of the heart. Deoxygenated blood is returned to the chambers of the heart via coronary veins; most of these converge to form the coronary venous sinus, which drains into the right atrium.

Why coronary circulation is important?

Why are the coronary arteries important? Since coronary arteries deliver blood to the heart muscle, any coronary artery disorder or disease can have serious implications by reducing the flow of oxygen and nutrients to the heart muscle. This can lead to a heart attack and possibly death.

What is the difference between pulmonary and coronary circulation?

The pulmonary circulation is the portion that brings blood to the lungs and back. The systemic circulation is the portion that brings oxygenated blood to the rest of the body. The heart gets its own supply of blood through the coronary circulation. Coronary arteries deliver oxygenated blood from the aorta to the heart.

What are the coronary arteries called?

The four main coronary arteries are the right coronary artery (RCA), left coronary artery (LCA), left anterior descending artery (LAD) and left circumflex artery.

What is the meaning of pulmonary circulation?

pulmonary circulation, system of blood vessels that forms a closed circuit between the heart and the lungs, as distinguished from the systemic circulation between the heart and all other body tissues. In the capillaries the blood takes up oxygen from the air breathed into the air sacs and releases carbon dioxide.

What is coronary circulation class 10?

Coronary circulation is the systemic circulation system of blood within the blood vessels. In this process of circulation, coronary arteries supply oxygenated blood to the heart muscles.

What do the coronary arteries do quizlet?

also called the left anterior descending or LAD, artery-supplies oxygenated blood to the anterior portion of the septum, anterior walls of the left atrium, and anterior walls of both ventricles. It descends into the anterior inter ventricular sulcus.
