Vena Cava Anatomy

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. I hope you find this anatomy guide helpful.

Inferior Vena Cava Anatomy Britannica

Left inferior vena cava.

Vena cava anatomy. The superior vena cava svc also known as the cava or cva is a short but large diameter vein located in the anterior right superior mediastinum. The left inferior vena cava is joined by the left renal vein and then crosses anterior to the aorta before it joins the right atrium forming a normal pre renal ivc. The inferior vena cava or ivc is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium 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. The inferior vena cava empties into the right atrium of the heart. Its walls are rigid and it has valves so the blood does not flow down via gravity.

It runs alongside the abdominal aorta but there are several important differences between their branches and tributaries which make perfect fodder for trick questions in exams. De oxygenated blood means most of the oxygen has been removed by tissues and therefore the blood is darker. It is formed by the union of the right and left brachiocephalic veins which provide venous drainage of the head neck and upper limbs.

The inferior vena cava is a large vein that carries de oxygenated blood from the lower body to the heart. Vena cava in air breathing vertebrates including humans either of two major trunks the anterior and posterior venae cavae that deliver oxygen depleted blood to the right side of the heart. The inferior vena cava is the largest vein in the human body.

This anomaly is caused by regression of the right supracardinal vein and the persistence of the left supracardinal vein. 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. It collects blood from veins serving the tissues inferior to the heart and returns this blood to the right atrium of the heart.

This blood comes from the legs and the lower torso of the body. Its latin name is related to its large pipe appearance in cadavers cava meaning hollow. The inferior vena cava ivc is the largest vein in the body.

At the level of t4 the superior vena cava receives the azygous vein which drains the upper lumbar region and thoracic wall. The superior vena cava contains venous blood from the head neck both upper limbs and from structures within the thorax. The ivc in a nutshell.

Although the vena cava is very large in diameter its walls are incredibly thin due to the low pressure exerted by venous blood.
