The renal arteries are paired arteries that supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle. The renal arteries carry a large portion of total blood flow to the kidneys. Up to a third of total cardiac output can pass through the renal arteries to be filtered by the kidneys.
Kidney. In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organs [1] that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. [2][3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres (41⁄2 inches) in ...
D012079. Anatomical terminology. [edit on Wikidata] The renal circulation supplies the blood to the kidneys via the renal arteries, left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output. [1]
The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The urinary tract is the body's drainage system for the eventual removal of urine. [1] The kidneys have an extensive blood supply via the renal arteries which ...
Mammalian kidney. Unipapillary, multilobar, smooth, bean-shaped camel kidney, in which the renal papillae are completely fused into the renal crest. [1] The mammalian kidneys are a pair of excretory organs of the urinary system of mammals, [2] being functioning kidneys in postnatal-to-adult individuals [3] (i. e. metanephric kidneys). [2]
Left renal artery passes deep to the left renal vein. Divides in hilum of kidney. Both arteries give inferior suprarenal arteries and ureteral branches. gonadal: L2: Visceral: yes: ant. Ovarian artery in females; testicular artery in males lumbar: L1-L4: Parietal: yes: post. Four on each side that supply the abdominal wall and spinal cord. The ...
Kidney (vertebrates) The kidneys are a pair of organs of the excretory system in vertebrates, which maintain the balance of water and electrolytes in the body (osmoregulation), filter the blood, remove metabolic waste products, and, in many vertebrates, also produce hormones (in particular, renin) and maintain blood pressure. [1][2][3][4] In ...
The bladder is a hollow organ in humans and other vertebrates that stores urine from the kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. [1][2] In humans, the bladder is a distensible organ that sits on the pelvic floor.
