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]
The signs and symptoms of NCS are all derived from the outflow obstruction of the left renal vein. The compression causes renal vein hypertension, leading to hematuria (which can lead to anemia) [4] and abdominal pain (classically left flank or pelvic pain). [5] The abdominal pain may improve or worsen depending on positioning. [5]
After filtration occurs, the blood moves through a small network of venules that converge into interlobular veins. As with the arteriole distribution, the veins follow the same pattern: the interlobular provide blood to the arcuate veins then back to the interlobar veins, which come to form the renal vein exiting the kidney for transfusion for ...
A cortical lobule (or renal lobule) is a part of a renal lobe. It consists of the nephrons grouped around a single medullary ray , and draining into a single collecting duct . Its near identical parallel is the rectal lobe [ citation needed ] , which is present in the majority of mammals.
A list of veins in the human body: Veins of the heart. Coronary sinus. Great cardiac vein; Oblique vein of left atrium; Middle cardiac vein; Small cardiac vein; Pulmonary veins; Superior vena cava. Brachiocephalic vein. Inferior thyroid vein; Inferior laryngeal vein; Pericardial veins; Pericardiophrenic veins; Bronchial veins; Vertebral vein ...
The stellate veins are minute [1] veins situated just beneath the fibrous capsule of the kidney. [citation needed] The stellate veins drain the superficial-most portion of the renal cortex. Groups of 5 or 6 stellate veins are arranged in a star-like pattern, converging centrally to drain into an interlobular vein as it penetrates into the renal ...
From anterior to posterior, the renal vein exits, the renal artery enters, and the renal pelvis exits the kidney. On the left hand side the hilum is located at the L1 vertebral level and the right kidney at level L1-2. The lower border of the kidneys is usually alongside L3.
It is located at the border of the renal cortex and renal medulla. [citation needed] Arcuate veins pass around the renal pyramids at the border between the renal cortex and renal medulla in an arch shape. [1] Arcuate veins receive blood from cortical radiate veins, and in turn deliver blood into the arcuate veins. [2]
