The large veins carrying blood from the kidneys usually lie in front of the corresponding arteries and join the inferior vena cava almost at right angles. The left vein is longer than the right vein because the inferior vena cava lies closer to the right kidney.
Does left gonadal vein drain into left renal vein?
The right gonadal vein (GV=testicular vein in men, ovarian vein in women) usually drains into the inferior vena cava (IVC) while the left gonadal vein drains into the left renal vein (RV).
What does the left renal artery supply?
The renal arteries carry a large volume of blood from the heart to the kidneys. The kidneys filter waste and excess fluid from the blood. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney. …
Why left testicular vein drains into left renal vein?
The left vein drains into the left renal vein. The left testicle is bigger than the right one; therefore, the left vein is longer than the right. Because the left vein is longer, it is subject to more difficulties when draining.Which way does blood flow through the renal vein?
Oxygenated blood comes to the kidneys from the right and left renal arteries off the abdominal aorta. Deoxygenated blood leaves the kidneys via the right and left renal veins that run into to the inferior vena cava.
What does the phrenic vein drain?
The inferior phrenic veins drain the diaphragm and follow the course of the inferior phrenic arteries; the right ends in the inferior vena cava; … while the other passes in front of the esophageal hiatus in the diaphragm and opens into the inferior vena cava.
Why is it called nutcracker syndrome?
In most cases, compression of the left renal vein is between the abdominal aorta — the main artery in the abdomen — and the superior mesenteric artery, which brings blood to the pancreas and intestines. Nutcracker syndrome gets its name because this compression is like a nutcracker crushing a nut.
Where does the left ovarian vein drain into?
Normal Ovarian Vein Anatomy The right ovarian vein drains into the inferior vena cava and the left ovarian vein into the left renal vein in most individuals (Fig. 1).What drains into the superior mesenteric vein?
The main function of the superior mesenteric vein is to drain the blood from the distal portion of the gastrointestinal tract. Specifically, it drains the small intestine, caecum, ascending and transverse parts of the colon, and distal parts of the stomach and greater omentum.
What does the Pampiniform plexus drain into?The pampiniform plexus is composed of the veins of the spermatic cord. These veins drain blood from the testes, epididymis, and vas deferens and eventually become the spermatic veins that drain into the main circulation of the kidneys.
Article first time published onCan a man with one testicle make a woman pregnant?
Yes, in most cases, people with one testicle can get someone pregnant. Remember, one testicle can provide enough testosterone for you to get an erection and ejaculate. This is also enough to produce adequate sperm for fertilization.
What is the function of left kidney?
They serve the body as a natural filter of the blood, and remove water soluble wastes, which are diverted to the bladder. In producing urine, the kidneys excrete wastes such as urea and ammonium, and they are also responsible for the reabsorption of water, glucose, and amino acids.
What is the entry point to the kidney for the renal artery renal vein lymphatics and nerves called?
The two kidneys receive about 25 percent of cardiac output. They are protected in the retroperitoneal space by the renal fat pad and overlying ribs and muscle. Ureters, blood vessels, lymph vessels, and nerves enter and leave at the renal hilum.
What happens to the renal arteries at the hilum of the kidney?
After passing through the hilum, the renal artery divides ordinarily into two large branches, and each branch divides into a number of smaller arteries, which bring blood to the nephrons, the functioning units of the kidney.
Which vessels drain filtered blood from the kidneys?
Renal veins. There are two renal veins, a left and a right. They branch off the inferior vena cava and drain oxygen-depleted blood from the kidneys.
What drains the urinary bladder?
The ureters are two tubes that drain urine from the kidneys to the bladder. Each ureter is a muscular tube that drains into the bladder. Smooth muscle contractions in the walls of the ureters, over time, send the urine in small spurts into the bladder, the organ where urine is stored before it can be eliminated.
Which vein receives blood from the renal veins?

What is SMA syndrome?
Superior mesenteric artery (SMA) syndrome is an uncommon but well recognized clinical entity characterized by compression of the third, or transverse, portion of the duodenum between the aorta and the superior mesenteric artery. This results in chronic, intermittent, or acute complete or partial duodenal obstruction.
What is renal collar?
Abstract: When the veins draining the left kidney surround the abdominal aorta in the form of a collar it is known as aortic renal collar. This condition has embryological basis and is referred as circum- aortic left renal vein or circum aortic renal collar in the literature.
What is a compressed kidney?
Summary. Listen. Renal nutcracker syndrome (NCS) is a condition that occurs when the left renal vein (the vein that carries blood purified by the left kidney) becomes compressed. Signs and symptoms can vary from person to person. Some people may not have symptoms, while others develop severe and persistent symptoms.
Where does inferior phrenic vein drain?
The inferior phrenic veins drain into the posterolateral aspect of the inferior vena cava at the level of T10. The left inferior phrenic vein drains higher than its right counterpart and is found superior to the oesophageal opening in the diaphragm.
Where does right suprarenal vein drain into?
right suprarenal vein drains directly into the inferior vena cava 1.
What are renal veins?
Listen to pronunciation. (REE-nul vayn) The main blood vessel that carries blood from the kidney and ureter to the inferior vena cava (a large vein that carries blood to the heart from the lower part of the body). There is a renal vein for each kidney.
Where does IMV drain?
Drains fromSuperior anorectal veinDrainage areaRectum, sigmoid, descending and distal transverse colon
What does the portal vein drain into?
The portal venules drain into hepatic sinusoids that, in turn, are drained by the hepatic veins into the inferior vena cava. The left and middle hepatic veins usually join and drain into the inferior vena cava separately but adjacent to the confluence of the right hepatic vein with the inferior vena cava.
What vein drains into the inferior vena cava?
Both the right and left common iliac veins join to form the inferior vena cava. The lumbar veins, as well as the left and right renal veins, empty into the inferior vena cava.
What veins drains the blood from the left ovary and the left testis?
The gonadal veins are paired structures that drain the gonads in males and females. In males it is called the testicular vein (or internal spermatic vein) and in females it is called the ovarian vein.
How is the renal vein formed?
The renal vein is formed by the union of two-to-three renal parenchymal veins in the renal sinus. It emerges from the renal hilum anterior to the renal artery and drains into the inferior vena cava at the level of L2.
Which plexus drains the bladder?

Which plexus drains the ovaries?
In females, the pampiniform plexus drains the ovaries. The right ovary drains from the plexus to the ovarian vein and then to the inferior vena cava.
Where does pampiniform plexus veins end?
Within the abdomen, the veins of the plexus merge to form a single testicular vein which ultimately drains into the inferior vena cava. In addition to the testis, the pampiniform plexus also drains the epididymis and proximal portion of the vas deferens.
