The nephron is the minute or microscopic structural and functional unit of the kidney.It is composed of a renal corpuscle and a renal tubule.The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule.
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
Renal corpuscle showing glomerulus and glomerular capillaries Figure 2: (a) Diagram of the juxtaglomerular apparatus: it has specialized cells working as a unit which monitor the sodiujuxtaglomerular apparatus: it has three types of specm content of the fluid in the distal convoluted tubule (not labelled - it is the tubule on the left) and adjust the glomerular filtration rate and the rate of ...
The nephron, together with the collecting duct into which it empties, is called the uriniferous tubule. Each uriniferous tubule, along with the vasculature supplying it, is embedded in the interstitium. [13] Approximately 18–26 different cell types have been described in mammalian kidneys, with a large variation in the range due to a lack of ...
Diagram of the circulation related to a single glomerulus, associated tubule, and collecting system The renal corpuscle in the cortex (outer layer) of the kidney. At the top, the renal corpuscle containing the glomerulus. The filtered blood exits into the renal tubule as filtrate, at right. At left, blood flows from the afferent arteriole (red ...
Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells which have large, spherical and central nuclei.. Simple cuboidal epithelium is found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, parts of the eye and thyroid, and in salivary glands.
As a result, the filtrate leaving the Bowman's capsule is very similar to blood plasma (filtrate or glomerular filtrate is composed of blood plasma minus plasma protein i.e. it contains all the components of blood plasma except the proteins) in composition as it passes into the proximal convoluted tubule.
The thin segment is a part of the renal tubule found between the proximal and distal tubules. The renal tubule and the renal corpuscle together comprise the nephron. [1] The thin segment is described as a U-shaped band, consisting of the two continuous parts: descending limb of loop of Henle; ascending limb of loop of Henle
