what is the function of the right and left coronary arteries?
531397
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away.

The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism. Oxygen is bound to molecules called haemoglobin that are on the surface of the red blood cells in the blood.

The left ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.

Arteries. The pulmonary arteries carry low-oxygen blood from the right ventricle of the heart to the lungs. Systemic arteries transport oxygenated blood from the left ventricle of the heart to the rest of the body. Veins.

The coronary arteries are classified as "end circulation", since they represent the only source of blood supply to the myocardium; there is very little redundant blood supply, that is why blockage of these vessels can be so critical.

Major Arteries of the Body. Arteries are the blood vessels of the body that carry blood away from the heart and to the organs and tissues of the body. The aorta is the largest artery in the body that exits the left ventricle of the heart.

The pulmonary arteries are blood vessels that carry blood from the right side of the heart through to the capillaries of the lungs. The blood that is carried is, unlike other arteries, without oxygen ("deoxygenated").

Its major functions include: maintenance of adequate cardiac position, separation from the surrounding tissues of the mediastinum, protection against ventricular dilatation, maintenance of low transmural pressure, facilitation of ventricular interdependence and atrial filling.

The cardiovascular system consists of the heart, blood vessels, and blood. This system has three main functions: Transport of nutrients, oxygen, and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide, nitrogenous wastes).

The heart is a pump that moves blood through the body. Blood begins its journey on the right side of the heart where it is pumped into the lungs to exchange carbon dioxide waste for oxygen. It then flows back to the left side of the heart where it is pumped out to the body through the arteries.

The left Atrium recieves oxygenated blood from the lungs and the left Ventricle discharges the oxygenated blood to the rest of the body. What is the job of the right Atrium and right Ventricle? The right atria receives unoxygenated blood. The right Ventricle discharges that blood into the lungs so it can be oxygenated.

The anterior cardiac veins reach the atrioventricular groove, where they pass deep to the right coronary artery and empty directly into the right atrium. ... The function of the anterior cardiac veins is to drain the venous blood of the upper part of the anterior surface of the right ventricle.

The coronary arteries are responsible for carrying nutrient rich, oxygenated blood from the left ventricle to the myocardium; while the coronary veins take nutrient – poor deoxygenated blood away from the myocardium and to the right atrium.

The Coronary Arteries are the blood vessels that supply blood to your heart. They branch off of the aorta at its base. The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries.

Function. The artery supplies the anterolateral myocardium, apex, and interventricular septum. The LAD typically supplies 45-55% of the left ventricle (LV) and is therefore considered the most critical vessel in terms of myocardial blood supply.

Left anterior descending artery. This smaller artery branches off the left coronary artery. It sends blood to the front of the left side of the heart. It also helps send blood to the middle (septum) of the heart.
