What does the anterior view of the heart show?

What does the anterior view of the heart show?

This anterior view of the heart shows the four chambers, the major vessels and their early branches, as well as the valves. The presence of the pulmonary trunk and aorta covers the interatrial septum, and the atrioventricular septum is cut away to show the atrioventricular valves.

What are the 4 major blood vessels of the heart?

The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary …

Which major blood vessel is found on the anterior side of the heart?

Left anterior descending artery (LAD) – supplies blood to the front and bottom of the left ventricle and the front of the septum. Pulmonary veins – bring oxygen-rich blood back to the heart from the lungs.

What is the anterior part of the heart?

The anterior of the heart is formed mainly by the right atrium and ventricle, due to the twisting of the heart during development, which causes the left atrium and ventricle to lie posteriorly.

Is the heart shown an anterior or posterior view?

The heart is oriented so that the anterior aspect is the right ventricle while the posterior aspect shows the left atrium (see Figure 6.2). The atria form one unit and the ventricles another. This has special importance to the electric function of the heart, which will be discussed later.

What are the five major vessels of the heart?

There are a number of great vessels associated directly with the heart. These are the ascending aorta, the pulmonary trunk, the pulmonary veins, the superior vena cava, and the inferior vena cava. The aorta is the most important artery of the systemic circulation.

Where is the anterior interventricular artery?

The anterior interventricular artery, often clinically termed the left anterior descending artery, is a branch of the left coronary artery. It originates at the left margin of the pulmonary trunk, anterior to the left atrial auricle.

Which of the blood vessels A to H is the vena cava?

The vena cava refers to the largest veins in the body, either the superior vena cava or the inferior vena cava. The left ventricle pumps blood into the aorta, which is the largest artery in the body.

Is anterior front or back?

Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body). Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot).

Is the heart anterior to the sternum?

The sternum lies anterior to the heart. Towards the back of the body. The heart lies posterior the sternum.

Why are anterior and posterior views of the heart important?

Anterior and posterior views of the heart may help provide a better perspective about the appearance and relative location of these major blood vessels. Anterior and posterior views of the major blood vessels of the heart. Review the anterior view of the major blood vessels of the heart and test yourself.

What is the right anterior branch of the heart?

Right anterior (atrial and ventricular) rami (Branches): These branches supply the sternocostal surface of the right atrium and right ventricle. 4. Right marginal artery: This artery runs towards the apex of the heart along the inferior border of the heart.

What are the major blood vessels in the heart?

Introduction to the Major Blood Vessels of the Heart: Blood exits the right ventricle through the pulmonary trunk artery. Approximately two inches superior to the base of the heart, this vessel branches into the left and right pulmonary arteries, which transport blood into the lungs.

What is the relationship between the veins and arteries?

We learned that your major arteries branch off of the aorta and continue to branch to supply blood to all regions of your body. Your veins do the opposite. They drain your body tissues, and then merge to make larger and larger veins and finally converge to form the largest veins in the body, called the venae cavae.
