What body system is the vena cava in?

What body system is the vena cava in?

The IVC is a large blood vessel responsible for transporting deoxygenated blood from the lower extremities and abdomen back to the right atrium of the heart. It has the largest diameter of the venous system and is a thin-walled vessel.

Is the vena cava in the circulatory system?

The superior vena cava is a vital structure in the human circulatory system that helps drain large amounts of deoxygenated blood from the head, eyes, neck, and upper limbs into the upper left chamber (atrium) of the heart.

What is the function of the posterior vena cava?

function. …of two major trunks, the anterior and posterior venae cavae, that deliver oxygen-depleted blood to the right side of the heart. The anterior vena cava, also known as the precava, drains the head end of the body, while the posterior vena cava, or postcava, drains the tail, or rear, end.…

What does the vena cava do in the excretory system?

Vena Cava’s Role in Excretion The vena cava (superior and inferior) return deoxygenated blood from the body and the head to the heart. From here the blood is pumped from the heart up through he lungs.

Which arterial vessel is located posterior to the inferior vena cava?

The right iliac arteries are just medial to the inferior vena cava and the right common iliac vein. The left common iliac vein lies partly medial to and partly behind (deep to) the left iliac arteries. The common iliac veins coalesce at a relatively acute angle over the L5 vertebral body to form the inferior vena cava.

What does the inferior vena cava do in the urinary system?

There are two renal veins, a left and a right. They branch off the inferior vena cava and drain oxygen-depleted blood from the kidneys. As they enter the kidneys, each vein separates into two parts. The posterior veins assist in draining the back section of each kidney, while the anterior veins assist the front part.

Does the inferior vena cava carry oxygenated or deoxygenated blood?

The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.

What is the function of the inferior vena cava in the urinary system?

Function. The primary function of the IVC is to carry deoxygenated blood that has circulated through the lower half of the body back to the right atrium of the heart.

The posterior vena cava is a major vein that returns blood from the body to the right atrium of the heart. The heart and the posterior vena cava along with all of the other blood vessels, regardless of size, comprise the cardiovascular system. This also is sometimes referred to as the circulatory system.

Why do the branches of the venae cavae have different names?

Branches of the venae cavae have different names because they are of different sizes and are located in different parts of the body. The superior vena cava is the vein that collects blood returned from the head and upper body, and the posterior vena cava receives blood from the lower portion of the body.

What is the difference between the superior and inferior vena cava?

inferior vena cava the venous trunk for the lower extremities and the pelvic and abdominal viscera; it empties into the right atrium of the heart. See Appendix 2-6. superior vena cava the venous trunk draining blood from the head, neck, upper extremities, and chest; it empties into the right atrium of the heart.

How many anterior vena cava does a human have?

Whereas many mammals, including humans, have only one anterior vena cava, other animals have two. Superior vena cava. Not far below the collarbone and in back of the right side of the breastbone, two large veins, the right and left brachiocephalic, join to form the superior vena cava.
