Shallow grooves called the interventricular sulci, containing blood vessels, mark the separation between ventricles on the front and back surfaces of the heart.
What is the function of the anterior interventricular artery?
It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system. Hence, blockage of this artery due to coronary artery disease can lead to impairment or death (infarction) of the conducting system.
What is the function of the interventricular sulcus?
The interventricular sulcus is a superficial groove or depression between the ventricles. It is of importance because this is where some of the large coronary arteries and veins run. Those vessels carry blood to and from the walls of the heart.

The anterior interventricular artery and the circumflex artery. Anterior interventricular artery DESCRIPTION: Branches off the left coronary artery, is located in the anterior interventricular sulcus. This artery is clinically referred to as the left anterior descending artery (LAD).
Why is the left anterior interventricular artery also known as the left anterior descending artery or LAD called the widow maker artery?
The LAD artery carries fresh blood into the heart so that the heart gets the oxygen it needs to pump properly. If it’s blocked, the heart can stop very fast — which is why this type of heart attack is called a “widowmaker.”
Is the anterior interventricular artery the same as the left anterior descending artery?
The left anterior descending (LAD) artery, also known as the anterior interventricular branch, is one of the two branches of the left coronary artery (the other branch being the circumflex (Cx) artery).
What is the function of the left anterior descending artery?
The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart.
What is the interventricular sulcus quizlet?
A deep sulcus that externally hows the separation of the atria and the ventricles. are shallow grooves that depict the surface boundaries between the two ventricles. A smaller vein that returns blood from the coronary circulation.
Does the interventricular septum contribute to contraction?
The lower part of the septum, which is the major part, is thick and muscular, and its much smaller upper part is thin and membraneous. During each cardiac cycle the interventricular septum contracts by shortening longitudinally and becoming thicker.
Does the interventricular septum contract with the right ventricle?
The interventricular septum functions as the posterior and left wall of the right ventricle.
Which blood vessels are responsible for providing blood flow to the cardiac tissue?
Coronary Circulation
The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.
Which vessel is situated on the anterior interventricular groove?
The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin. The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein.
…

Where does the left anterior descending artery supply blood to?
The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the lateral side and back of the heart.
What are the functions of the fibrous skeleton?
The fibrous skeleton is concentrated at the base of the ventricular mass. It provides electrical insulation at the atrioventricular level and fibrous continuity for the leaflets of the mitral, aortic, and tricuspid valves.
Which of the following blood vessels carries oxygenated blood?
Detailed Solution
| PULMONARY VEINS | It carries oxygenated blood from the lungs to the heart. |
|---|---|
| AORTA | It carries oxygenated blood from the heart to the rest of the body. |
Which vessel travels in the right atrioventricular sulcus?
The right coronary artery occupies the right atrioventricular groove (Adams and Treasure, 1985). Its first part extends to the acute margin of the ventricular mass, where it gives rise to the acute marginal artery, giving rise to many atrial branches from its cranial surface.
What vein is in the posterior interventricular sulcus?

What is blood vessels function?
The function of blood vessels is to deliver blood to the organs and tissues in your body. The blood supplies them with the oxygen and nutrients they need to function. Blood vessels also carry waste products and carbon dioxide away from your organs and tissues.
What is the function of the blood vessels and capillaries?
Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.
What is the main function of the blood in circulatory system?
The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
