What is the role of aorta and vena cava in the circulation?

aorta: The great artery which carries the blood from the heart into systemic circulation. venae cavae: The two large vessels, the superior and inferior vena cava, that bring deoxygenated blood from systemic circulation to the heart.

What is posterior vena cava?

The posterior or inferior vena cava is a large vein that carries deoxygenated blood from the lower and middle part of the body into the right atrium of the heart. It runs posterior or behind the abdominal cavity.

What is aorta and vena cava?

Summary – Aorta vs Vena Cava

Aorta is the main or the largest artery which carries oxygenated blood from the heart to the whole body. Vena cava is the large veins that bring deoxygenated blood from the body to the heart.

What vessel is posterior to the superior vena cava and ascending aorta?

Right Pulmonary Artery

It passes posterior to the ascending aorta and the inferior vena cava to reach the hilum of the lung. The azygos vein lies posteriorly, separated by the right main bronchus.

What are the major arteries and veins in the body and which regions do they serve?

The major blood vessels that are connected to the heart include 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 ...

What structure of the heart contains the largest veins and arteries?

The Aorta. The aorta is the largest of the arteries in systemic circulation. Blood is pumped from the left ventricle through the aortic valve into the aorta.

What is the structure of the vena cava?

The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.

What is the role of aorta?

The aorta is the main artery that carries blood away from your heart to the rest of your body. The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.

Where is the posterior vena cava?

The inferior vena cava (also known as IVC or the posterior vena cava) is a large vein that carries blood from the torso and lower body to the right side of the heart. From there the blood is pumped to the lungs to get oxygen before going to the left side of the heart to be pumped back out to the body.

Where is the aorta and vena cava?

Aorta is attached to the left ventricle of the heart. Vena Cava is attached to the right atrium of the heart.

How do the walls of the aorta and vena cava compare?

In summary, aorta contains less collagen than elastin, but vena cava contains almost four times more collagen than elastin. In vena cava, the elastin is longitudinally oriented and the collagen becomes more circumferentially oriented and straightens at low levels of strain.

Are the vessels that branch off the ascending aorta and supply the walls of the heart with oxygenated blood?

The ascending aorta has two branching vessels, the left and right coronary arteries, which supply blood to the heart muscle.

What is the name of the structure which forms a major branch from the ascending aorta and passes inferior to the left auricle?

The only branches of the ascending aorta are the coronary arteries, which arise just where it starts. The arch of the aorta makes a complete 180º turn. Beneath the arch of the aorta is the pulmonary trunk, dividing into the two pulmonary arteries: here's the left one. This is the ligamentum arteriosum.

What are branches of the aorta?

The convexity of the aortic arch gives off three branches; the brachiocephalic trunk, the left common carotid artery and the left subclavian artery.
