What system is the posterior vena cava?

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 body system is the vena cava in?

function in cardiovascular system

The inferior vena cava is a large, valveless, venous trunk that receives blood from the legs, the back, and the walls and contents of the abdomen and pelvis.

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.

Where is the anterior vena cava located?

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. In humans these veins are respectively called the superior and inferior venae cavae.

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.

What is the function of the anterior and 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.…

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 is vena cava and aorta?

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.

Where is vena cava from?

The inferior vena cava arises from the confluence of the common iliac veins at the level of L5 vertebra, just inferior to the bifurcation of the abdominal aorta. It then ascends the posterior abdominal wall, to the right side of the aorta and the bodies of the L3-L5 vertebrae.

Does the vena cava have valves?

The valve of the inferior vena cava (eustachian valve) is a venous valve that lies at the junction of the inferior vena cava and right atrium.

Where does the superior vena cava start?

The superior vena cava (SVC) starts at the confluence of the brachiocephalic veins behind the first right costal cartilage, and ends at the level of the third right costal cartilage where it drains into the right atrium. The SVC is about 7 cm long and 2 cm wide.

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 excretory system?

The Excretory system is responsible for the elimination of wastes produced by homeostasis. There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. Every human has two kidneys.

What are the main function of excretory system?

The function of the excretory system to remove wastes from the body. These wastes include water, CO2, nitrogen, salts, and heat. Metabolism: The process of the body coverting food into energy. As a result of metabolism, there are waste products.

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.
