What is the anterior vena cava?

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.

Where is the anterior vena cava?

su·pe·ri·or ve·na ca·va. Returns blood from the head and neck, upper limbs, and thorax to the posterosuperior aspect of the right atrium; formed in the superior mediastinum by union of the two brachiocephalic veins. Synonym(s): vena cava superior [TA] , precava.

What is the vena cava function?

A large vein that carries blood to the heart from other areas of the body. 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.

Are there 2 vena cava?

The venae cavae (/ˈviːni ˈkeɪvi/; from the Latin for "hollow veins", singular "vena cava" /ˈviːnə ˈkeɪvə/) are two large veins (great vessels) that return deoxygenated blood from the body into the heart. In humans there are the superior vena cava and the inferior vena cava, and both empty into the right atrium.

Where does blood come from in the anterior vena cava?

Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve.

What is the function of the vena cava and aorta?

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.

Why is it called 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'.

What is the superior vena cava?

The SVC is a large vein that drains blood away from the head, neck, arms, and upper chest and into the heart. SVCS is most often seen in people who have cancer.

Is vena cava a vein or artery?

The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium). The superior vena cava carries blood from the brain and arms into the top of the right atrium.

What is the biggest vein in the human body?

The two largest veins in the body are the superior vena cava, which carries blood from the upper body directly to the right atrium of the heart, and the inferior vena cava, which carries blood from the lower body directly to the right atrium.

What is the longest vein in the body?

Great Saphenous Vein (GSV) – The GSV is the large superficial vein of the leg and the longest vein in the entire body. It can be found along the length of the lower limb, returning blood from the thigh, calf, and foot to the deep femoral vein at the femoral triangle. The femoral triangle is located in the upper thigh.

What is the largest artery in the body?

Aorta Anatomy

The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.

What is the vena cava made of?

It is composed of collagen and elastic fiber connective tissues. This layer allows the vena cava to be strong and flexible. The middle layer is composed of smooth muscle and is called the tunica media. Smooth muscle in this layer allows the venae cavae to receive input from the nervous system.

Where does blood go after leaving the lungs?

Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Where does blood go after leaving the aorta?

Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body.
