Anatomy and Phisology of kidney device

Urogenital device – it is formed from urinary and genital systems. The most part of excretion products are eliminated through an organs system called excretory system

Urinary tract – has 2 kidneys and exit ways of urin: potassium, basins, ureters, bladder and urethra.

Kidneys – secretory organs of urine, have grains and beans are located on both sides of the lumbar spine. Each kidney is surrounded by Celulose-fat layer and coated by a inextensible fibrous capsule located in the renal lodge.

Nefron – kidney anatomical and physiological unit, consisting of glomerule [vascular pole] and urinifer tube [urinary pole]. Nephron number in the two kidneys is valued at 2 million.

Glomeruli – the first element of nephron – consists of a bundle of capillaries resulting from an arterial branches involved, arising from renal artery. Capillaries then unite to form a eferent arteriola which capillarise again around the first portion of the tube urinifer.

Urinifer tube – the second part of the nephron – is presented as a channel of 50 mm long, consisting of the following segments Bowman capsule, proximal tube contorta, Ansa Henle, distal and Tubes contorta tube collectors. Bowman capsule – the form of a cup that surround the glomeruli and is composed of two lamina.

Bowman capsule with glomeruli it contains, is called the particle Malpighi. From Tubes contorta remotely through collector channels and common channels that open in the renal papillae, formed passes urine potassium and hence the basin.

Urinary bladder – Urethra-channel – is a trajectory very short woman, unlike man, that path is long and crosses the prostate, where the possibility of a urethral compresiunii adenoma, prostate, to echo the entire urinary tree.
