Where does the inferior vena cava drain blood into?
Where does the inferior vena cava drain blood into?
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. 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.
What does the superior and inferior vena cava drain?
Superior Vena Cava: This large vein brings de-oxygenated blood from the head, neck, arm, and chest regions of the body to the right atrium. Inferior Vena Cava: This vein brings de-oxygenated blood from the lower body regions (legs, back, abdomen and pelvis) to the right atrium.
What does superior vena cava drain to?
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.
Where does the superior vena cava and inferior vena cava drain?
After circulating through the body systemically, deoxygenated blood returns to the right atrium of the heart through either the SVC, which drains the upper body, or the inferior vena cava (IVC) that drains everything below the diaphragm.
Where does the superior vena cava empty?
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.
Where does the vena cava carry blood to?
heart
What is the vena cava? The superior vena cava and inferior vena cava are very large veins that bring deoxygenated blood to your heart to get oxygen. Your inferior vena cava, your body’s largest vein, carries oxygen-depleted blood back to your heart from the lower part of your body (below your diaphragm).
Where does the blood from the vena cava go?
Your superior vena cava and inferior vena cava have the important function of carrying oxygen-poor blood to your heart’s right atrium, where it moves into your right ventricle and then to your lungs (through your pulmonary artery) to trade in carbon dioxide for oxygen.
Where do the superior and inferior vena cava enter the heart?
The IVC enters the right atrium of the heart after coursing through the diaphragm, entering the posterior inferior aspect of the atrium. The IVC enters the right atrium inferior to the entrance of the superior vena cava (SVC). The IVC is a mostly symmetric vessel with a few exceptions.
Where does the superior vena cava drain blood from?
The superior vena cava is a vital structure in the human circulatory system that helps drain large amounts of deoxygenated blood from the head, eyes, neck, and upper limbs into the upper left chamber (atrium) of the heart.
Where does blood go from the superior vena cava?
Where do the inferior and superior vena cava converge?
Superior & Inferior Vena Cava Function The blood then travels through the short and thin-walled superior vena cava inferiorly where it joins the heart at the right atrium depositing the deoxygenated blood.
What are the veins draining to the inferior vena cava?
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. Inferior vena cava in a cadaver. Notice how the largest tributaries are the left and right renal veins.
