The renal lobe is a portion of a kidney consisting of a renal pyramid and the renal cortex above it. [1] In humans, on average there are 7 to 18 renal lobes. [medical citation needed] It is visible without a microscope, though it is easier to see in humans than in other animals.
The renal corpuscle is a blood-filtering part of the nephron and is located in the cortex. The renal tubule extends from the renal corpuscle to the medulla into the loop of Henle and then returns back to the cortex. Finally, the renal tubule flows with its distal end into its collecting duct, which is common to several nephrons.
The avian kidney is lobulated and usually consists of three lobes. [80] The lobes are divided into lobules, each of which has a cortex and a medulla. [ 67 ] [ 3 ] The medulla of the each lobule is shaped like a cone, and, unlike mammals, it is not subdivided into the inner and outer regions, while structurally it is similar to the outer medulla ...
Part of the renal cortex, a medullary ray is a collection of renal tubules that drain into a single collecting duct. [citation needed] Renal histology is the study of the microscopic structure of the kidney. The adult human kidney contains at least 26 distinct cell types, [25] including epithelial, endothelial, stromal and smooth muscle cells ...
Within the nephron of the kidney, the ascending limb of the loop of Henle is a segment of the heterogenous loop of Henle downstream of the descending limb, after the sharp bend of the loop. This part of the renal tubule is divided into a thin and thick ascending limb ; the thick portion is also known as the distal straight tubule , in contrast ...
It contains the renal corpuscles and the renal tubules except for parts of the loop of Henle which descend into the renal medulla. It also contains blood vessels and cortical collecting ducts. The renal cortex is the part of the kidney where ultrafiltration occurs. [2] Erythropoietin is produced in the renal cortex. [3]
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.
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 .
