Inferior vena cava

Tributaries of the inferior vena cava Author: Charlotte O'Leary BSc, MBChB • Reviewer: Last reviewed: July 01, 2022 Reading time: 8 minutes The inferior vena cava, the largest vein in the human body, transports blood from the tributaries of the inferior vena cava. This article will discuss the anatomy of these tributaries in detail, followed by any relevant clinical notes. + Show all Tributaries Apart from the common iliac veins, there are 6 pairs of veins, 2 singular veins and a hepatic group of veins, which drain into the inferior cava directly. They include: • Four pairs of • The right gonadal vein • A pair of • The right suprarenal vein • A pair of inferior phrenic veins • A group of hepatic veins Lumbar veins (posterior view) The third and fourth lumbar veins usually enter the posterior aspect of the inferior vena cava but the first and second lumbar veins are more variable. The first lumbar vein occasionally drains into the inferior vena cava but usually drains into the second lumbar vein, the ascending lumbar vein or the second lumbar vein usually joins the inferior vena cava but it may occasionally drain into the third lumbar vein or the ascending lumbar vein. Right gonadal vein The right gonadal vein ( ovarian in females and testicular in males) joins the inferior vena cava just inferior to the level of the left renal vein at an acute angle. It opens into its right anterolateral aspect and is usually double in its course. Right ovarian vein (anterior view) Renal v...

Together, your superior vena cava and inferior vena cava collect deoxygenated blood from your whole body and bring it back to your heart for new oxygen. This is why the vena cava veins are the largest veins in your body. Your upper body veins send blood to your superior vena cava and your lower body veins empty blood into your inferior vena cava. Overview Vena cava veins take blood back to the 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 Think of it like a bus line. The downtown line is like the smaller veins from your lower body (such as veins from your kidneys, liver and lower back area) that bring deoxygenated blood into your inferior vena cava. Blood from those other veins gets on the inferior vena cava bus to go to your heart. Your uptown line (upper body) veins, such as the veins in your upper back and chest, take deoxygenated blood onto your superior vena cava bus for return to your heart. Your heart is the hub or destination where all the deoxygenated blood from the uptown and downtown bus lines (veins) goes. Anatomy Where is the vena cava located? Your inferior vena cava and superior vena cava are both on your heart’s right side. Your right and left innominate (or brachiocephalic) veins merge to form your superio...

Deoxygenated blood means most of the oxygen has been removed by tissues, and therefore the blood is darker. This blood comes from the legs and the body’s lower torso. The inferior vena cava empties into the right atrium of the heart. The right atrium is located on the right back side of the heart. The inferior vena cava runs posterior, or behind, the abdominal cavity. This vein also runs alongside the right vertebral column of the spine. The inferior vena cava is the result of two major leg veins coming together. These leg veins are called iliac veins. The iliac veins come together at the small of the back, at the fifth lumbar vertebra. Once the iliac veins have merged, they form the inferior vena cava, which transports the deoxygenated blood to the heart. Last medically reviewed on February 21, 2020

The vena cava is a large vein that collects blood from either the upper or lower half of your body. It receives blood from several smaller veins. This is blood with the oxygen removed that the vena cava transports to the right side of the heart. Blockage or injury of a vena cava can have serious consequences for your health. What Is the Vena Cava? A vena cava (plural: venae cavae) is a large vein that carries blood to the heart. You have two venae cavae: the superior vena cava and the inferior vena cava. Together, these large veins carry deoxygenated (with the oxygen removed) blood from all over the body to the right atrium of the heart. This blood moves to the right ventricle of the heart, which pumps it to the lungs through the pulmonary artery. These large veins are formed by the merging of smaller veins. After the venae cavae are formed, smaller veins connect with them along their path. The blood from all over the head, arms, and chest is collected by various veins that all contribute to the superior vena cava. Similarly, the blood from the lower limbs, pelvis, and abdominal organs all reach the inferior vena cava. When you're at rest, your heart pumps five to six liters of blood a minute. If you're exercising hard, this can go up to 35 liters a minute. The venae cavae bring this blood back. What Does the Vena Cava Do? The venae cavae are veins, so they have one job — to carry blood from all the tissues and organs of the body to the heart. The superior vena cava carrie...

Synonyms: IVC The inferior vena cava (IVC) is the largest vein of the human body. It is located at the posterior The inferior vena cava anatomy is essential due to the vein’s great drainage area, which also makes it a hot topic for anatomy exams. For that reason, this page will cover the IVC anatomy in a way that’s easy to read and understand. Key facts Definition and function The vein that collects deoxygenated blood from the abdomen, pelvis and lower limbs and carries it to the right atrium of the heart Source Common iliac veins (L5) Tributaries Inferior Phrenic, right Suprarenal, Renal, right Testicular (gonadal), Lumbar, common Iliac and Hepatic veins Mnemonic: Portal System Returns To Liver In Humans Clinical relations Inferior vena cava thrombosis Synonyms: IVC The inferior vena cava arises from the confluence of the inferior vena caval foramen of the The tributaries of the IVC correspond to the branches of the abdominal aorta. Note that some professors will want you to know at which vertebral level the IVC gets its direct tributaries, so they are as follows: • The direct tributaries are the inferior phrenic veins (T8), right suprarenal (L1), renal (L1), right testicular (gonadal) (L2), lumbar (L1-L5), common iliac (L5) and hepatic (T8). If you want an easy way to remember them just memorise the mnemonic ' Portal System Returns To Liver In Humans'. • Left gonadal and left suprarenal renal veins drain first into the left • The veins of the The inferior vena cava commu...

What is an inferior vena cava filter placement? An inferior vena cava (IVC) filter is a small device that can stop blood clots from going up into the lungs. The inferior vena cava is a large vein in the middle of your body. The device is put in during a short surgery. Veins are the blood vessels that bring oxygen-poor blood and waste products back to the heart. Arteries are the blood vessels that bring oxygen-rich blood and nutrients to the body. A deep vein thrombosis (DVT) is a blood clot that forms in a vein deep inside the body. A clot occurs when blood thickens and clumps together. In most cases, this clot forms inside one of the deep veins of the thigh or lower leg. The veins in your legs have tiny valves that help keep blood moving back up toward the heart. But a DVT may damage one or more of these valves. This causes them to weaken or become leaky. When this happens, blood starts to pool in your legs. This can also happen if you are immobile for a long period of time. Normally, muscles in the leg help blood move up in the veins when the muscles contract. When blood flows very slowly through the veins, this increases the risk that cells in the blood will stick together and form a clot. DVT is a serious medical condition that can cause swelling, pain, and tenderness in your leg. In some cases, a deep clot in a leg vein can break free and stick in a vessel in the lung. This can cause a blockage in the vessel called a pulmonary embolism. Pulmonary embolism can cause se...
