What do the superior and inferior vena cava do?
A large vein that carries blood to the heart from other areas of the body. The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
Where does the superior vena cava carry blood to?
The superior vena cava carries blood from the brain and arms into the top of the right atrium. The inferior vena cava carries blood from the legs and abdominal cavity into the bottom of the right atrium. The vena cava are also called the “central veins”.
Where does blood flow into after the superior and inferior vena cava?
right atrium
Both the superior vena cava and inferior vena cava empty blood into the right atrium. Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs.
What does the superior vena cava deliver blood to?
The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart.
Where does blood entering the inferior vena cava come from?
Blood from the left and right femoral veins enters the IVC via the left and right common iliac veins, respectively. Blood from the abdominal viscera travels into the portal vein and enters the IVC via the hepatic veins after traversing the liver and its sinusoids.
Where does the blood from the inferior vena cava come from?
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.
Where does the inferior vena cava receive blood from?
Where is the inferior vena cava?
The IVC lies along the right anterolateral aspect of the vertebral column and passes through the central tendon of the diaphragm around the T8 vertebral level. 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.
Where does blood flow to after the vena cava?
The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium. Next is the pulmonary artery that carries blood from the right ventricle to the lungs. The aorta is the body’s largest artery.
Are superior and inferior vena cava connected?
The inferior vena cava communicates with the superior vena cava through the collateral vessels, which include the azygos vein, lumbar veins, and vertebral venous plexuses. Notice how the largest tributaries are the left and right renal veins.
Where do the inferior and superior vena cava meet?
The inferior vena cava meets the heart at the posterior aspect of the right atrium. Like the superior vena cava, there is no valve between the inferior vena cava and the right atrium.
Where does the inferior vena cava bring blood?
In brief, superior vena cava and inferior vena cava are two veins that bring deoxygenated blood to the heart. In fact, they bring blood to the right upper chamber of the heart, which is the right atrium.
What is the function of the vena cavae?
The venae cavae are a pair of largest veins in the body. There are two venae cavae which are the superior vena cava and the inferior vena cava. The function of these veins is to transport deoxygenated blood from different parts of the body to the heart. This deoxygenated blood is then transported through…
Why is the pressure in the vena cava low?
Since both types of veins carry blood against the gravity, they contain valves that prevent the backflow of the blood. The pressure of the blood inside each vena cava is low. Muscular contractions are the driving force of the blood inside the vena cava.
What causes superior and inferior vena cava syndrome?
The swelling may slow or obstruct blood flow to the heart. Superior vena cava syndrome is most often caused by lung cancer and lymphoma. Inferior vena cava syndrome is caused by the obstruction or compression of the inferior vena cava.
