The Efferent arterioles are a group of blood vessels that are part of the urinary system of many animals. The efferent arterioles form from a convergence of the capillaries of the glomerulus and further divide into a second group of capillaries, the peritubular capillaries. Nephron of the kidney A nephron is the basic structural and functional unit of the kidney. ... Latin is an ancient Indo-European language originally spoken in the region around Rome called Latium. ... Medical Subject Headings (MeSH) is a huge controlled vocabulary (or metadata system) for the purpose of indexing journal articles and books in the life sciences. ... The arterial system The blood vessels are part of the circulatory system and function to transport blood throughout the body. ... The urinary system is the organ system that produces, stores, and carries urine. ... Phyla Porifera (sponges) Ctenophora (comb jellies) Cnidaria (coral, jellyfish, anemones) Placozoa (trichoplax) Subregnum Bilateria (bilateral symmetry) Acoelomorpha (basal) Orthonectida (parasitic to flatworms, echinoderms, etc. ... Capillaries are the smallest of a bodys blood vessels, measuring 5-10 μm. ... Glomerulus refers to two unrelated structures in the body, both named for their globular form. ...

Human kidneys viewed from behind with spine removed The kidneys are bean-shaped excretory organs in vertebrates. ... The renal capsule is a tough fibrous layer surrounding the kidney and covered in a thick layer of perinephric adipose tissue. ... The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. ... The renal medulla is the innermost part of the kidney. ... The renal sinus is a cavity within the kidney which is occupied by the renal pelvis, renal calices, blood vessels, nerves and fat. ... Renal pyramids are cone-shaped tissues of the kidney. ... A calyx is a part in the kidney. ... The renal pelvis represents the dilated proximal part of the ureter. ... Nephron of the kidney A nephron is the basic structural and functional unit of the kidney. ... A renal corpuscle is the initial filtering component of a nephron in the kidney. ... Glomerulus refers to two unrelated structures in the body, both named for their globular form. ... Bowmans capsule is a blind sac at the beginning of the tubular component of a nephron in the mammalian kidney. ... The loop of Henle is a section of the nephron that leads from the proximal convoluted tubule to the distal convoluted tubule in the kidney. ... Kidney nephron The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting duct system. ... The collecting duct system of the kidney consists of: The connecting tubule The cortical collecting duct The medullary collecting duct Categories: | ... The juxtaglomerular apparatus is a renal structure consisting of the macula densa and juxtaglomerular cells. ... In the kidney, the macula densa is an area of closely packed specialized cells lining the distal convoluted tubule where it lies next to the glomerular vascular pole. ... The juxtaglomerular cells are specialized cells that stimulate the secretion of the adrenal hormone aldosterone and play a major role in renal autoregulation, the kidneys self-governance. ...

Ultrafiltration (UF) is a pressure-driven membrane process for purifying and concentrating macromolecular (10^3 - 10^6 Da) solutions, especially protein solutions. ... Countercurrent exchange is a mechanism used to transfer some component of a fluid from one flowing current of fluid to another across a permeable barrier between them. ... Antidiuretic hormone (ADH), or arginine vasopressin (AVP), is a peptide hormone produced by the hypothalamus, and stored in the posterior part of the pituitary gland. ... Aldosterone is a steroid hormone synthesized from cholesterol by the enzyme aldosterone synthase. ... Atrial natriuretic factor (ANF), or atrial natriuretic peptide (ANP), is a peptide hormone that is released by walls of the cardiac atrium in response to high NaCl concentration, high extracellular fluid volume, or high blood volume. ...
