What is superior and inferior vena cava

Furthermore superior vena cava drains blood from the head neck arms and the upper chest wall while inferior vena cava. The superior vena cave is a vessel with thin walls and low pressure which makes it susceptible to conditions that increase the venous pressure.

The inferior vena cava anatomy is essential due to the veins great drainage area which also makes it a hot topic for anatomy exams.

What is superior and inferior vena cava. The superior vena cava delivers blood from the head and chest area to the heart while the inferior vena cava returns blood from the lower body regions to the heart. As blood is circulated along the pulmonary and systemic circuits oxygen-depleted blood returning to the heart is pumped to the lungs by way of the pulmonary artery. Superior vena cava and inferior vena cava collectively known as the venae cavae are the two largest veins that carry deoxygenated blood from lower and upper halves of the body into the heart.

Both deliver blood to the right atrium of the heart. Both these veins do. The superior vena cava collects blood from aspects of the body above the diaphragm while the inferior vena cava collects blood from below the.

5 min read. The main difference between superior and inferior vena cava is that the superior vena cava drains blood from the upper part of the body while the inferior vena cava drains blood from the lower part of the body. Furthermore superior vena cava drains blood from the head neck arms and the upper chest wall while inferior vena cava.

The superior vena cava is located in the upper chest and is formed by brachiocephalic vein while the inferior vena cava is located in the back region of the body and runs along the spine and parallel to the aorta. Anatomically speaking the walls of the vena cavae are made up of three layers of tissues. The superior vena cave is a vessel with thin walls and low pressure which makes it susceptible to conditions that increase the venous pressure.

This is an important factor when it comes to conditions of the superior vena cava. 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. Its latin name is related to its large pipe appearance in cadavers cava meaning hollow.

The inferior vena cava IVC is the largest vein of the human body. It is located at the posterior abdominal wall on the right side of the aorta. The IVCs function is to carry the venous blood from the lower limbs and abdominopelvic region to the heart.

The inferior vena cava anatomy is essential due to the veins great drainage area which also makes it a hot topic for anatomy exams. The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium. The aorta is the largest artery in the body.

It carries oxygenated blood from the left ventricle of the heart into systemic circulation. The inferior vena cava and the superior vena cava known collectively as venae cavae are large veins in the human body. The superior vena cava is in the upper chest where it is responsible for carrying deoxygenated blood from the upper body neck face and arms to the hearts right atrium.

The inferior vena cava is a large vein that carries deoxygenated blood from the lower body to the heart. The inferior vena cava is also referred to as 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 heartIt is formed by the joining of the right and the left common iliac veins usually at the level of the fifth lumbar vertebra.

The inferior vena cava is the lower inferior of the two venae cavae the two large veins that carry deoxygenated blood from. Interruption of the inferior vena cava IVC with azygos continuation is a rare congenital anomaly in which the IVC is interrupted below the hepatic vein and venous return beyond this point is restored by the dilated azygos and hemiazygos veins draining into the superior vena cava. What is superior vena cava syndrome SVCS.

Superior vena cava syndrome SVCS is a group of problems caused when blood flow through the superior vena cava SVC is slowed down. The SVC is a large vein that drains blood away from the head neck arms and upper chest and into the heart. Superior vena cana collects blood from the anterior parts of the body whereas inferior vena cava collects blood from posterior parts of body.

Superior vena cava is a large vein which brings deoxygenated blood into the right atrium of the heart from the upper half of the body including neck head and upper limbs. The superior vena cava is a thin-walled low pressure vessel which makes it vulnerable to compression. Superior vena cava obstruction can occur either due to external compression or from an occlusion within the vessel lumen itself.

The most common cause of SVC obstruction is malignancy typically from lung cancer lymphoma or metastatic disease. The inferior vena cava transports blood up from the lower body. Two major veins the left and right brachiocephalic veins join in the upper chest to form the superior vena cava.

From that point it is just a short distance down to the heart. The superior vena cava is a major vein in your upper body. It carries blood from your head neck upper chest and arms to the heart.

Superior vena cava syndrome SVCS happens when the superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS. The drawing below shows where the superior vena cava is in your body.

The inferior vena cava IVC begins at the confluence of the common iliac veins which corresponds to the L4-L5 level Figs. 14-1 and 14-2. 35 The left common iliac vein and IVC course between the right common iliac artery and the spine at this site.

Superior vena cava syndrome SVCS is a group of symptoms that can occur in people who have lung cancer lymphoma or other cancers that involve the center of the chest. It also can occur from noncancer causes. SVCS is serious when it occurs in adults.

It is life-threatening in children. The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium. The aorta is the largest artery in the body.

It carries oxygenated blood from the left ventricle of the heart into systemic circulation.
