The left gonadal vein usually empties into (inferior aspect of) [2] the ipsilateral renal vein [2] [3]: 1144 proximally to where the renal vein crossing over the aorta. [2] The right gonadal vein typically empties directly into the (right anterolateral aspect of) inferior vena cava, joining it at an acute angle, some 2 cm inferior to the ...
On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly. [1] On the left, they drain into the renal vein which in turn drains into the inferior vena cava. [1] By contrast, all the lumbar veins and hepatic veins usually drain directly into the inferior vena cava. [1]
The renal veins in the renal circulation, are large-calibre [1] veins that drain blood filtered by the kidneys into the inferior vena cava. There is one renal vein draining each kidney. [citation needed] Each renal vein is formed by the convergence of the interlobar veins of one kidney. [2]
Blood passes from branches of the portal vein through cavities between "plates" of hepatocytes called sinusoids. Blood also flows from branches of the hepatic artery and mixes in the sinusoids to supply the hepatocytes with oxygen. This mixture percolates through the sinusoids and collects in a central vein which drains into the hepatic vein.
Valveless testicular veins are a major contributing factor to varicocele. [1] Since the left testicular vein goes all the way up to the left renal vein before it empties, this results in a higher tendency for the left testicle to develop varicocele because of the gravity working on the column of blood in this vein, compared to the right internal spermatic vein.
the right ends in the inferior vena cava; the left is often represented by two branches, one of which ends in the left renal or suprarenal vein, while the other passes in front of the esophageal hiatus in the diaphragm and opens into the inferior vena cava.
The ovarian vein, the female gonadal vein, carries deoxygenated blood from its corresponding ovary to inferior vena cava or one of its tributaries. It is the female equivalent of the testicular vein, and is the venous counterpart of the ovarian artery. It can be found in the suspensory ligament of the ovary. [1]
Below the superficial inguinal ring they unite to form three or four veins, which pass along the inguinal canal, and, entering the abdomen through the deep inguinal ring, coalesce to form two veins. These again unite to form a single vein, the testicular vein , which opens on the right side into the inferior vena cava , at an acute angle, and ...
