The anatomical nemamiriro itsvo uye nephron

Urinary munhu anopa excretion pamusoro nitrogenous matongo zvakapararira munzvimbo nedanho muviri, uye fluid inodzora BP, vhoriyamu ropa, asidhi-nechigadziko mwero uye electrolyte mwero. Central nhengo nezvezvimwe zvinetso zvedundira ndivo neitsvo.

Funga sechivako yacho itsvo. Itsvo dziri symmetrically pamusoro mativi ose nomuzongoza pachiyero chityu kuna XII I-II of lumbar vertebra, retroperitoneal, takapoteredzwa gobvu rukoko mafuta tishu. Mumwe itsvo kusiyanisa mberi neshure hukawanika, okumusoro mapango, lateral uye medial divi. Nepamagedhi kupinda itsvo inopinda uye inosiya neurovascular masumbu. The itsvo rworudyi iri zvishoma pazasi kuruboshwe, izvo chokuita chiropa yaiva pamusoro. Itsvo mamiriro anosiya shoma kufamba nenzira wehunyambiri chinzvimbo. Nzvimbo netsvo kunoenderana mhando bumbiro kwevanhu (hypersthenic, asthenic kana normosthenic). Gate itsvo kuyerera munzvimbo renal chiuno, zvikuru nezviduku nemikombe, apo misoro renal mapiramidhi iri muchimiro papillae. On pemvura papilla ane buri duku kuburikidza iyo weti asunungurwa.

Internal itsvo mamiriro iri nani kunzwisisa. Nephron - inokosha STRUCTURAL Unit itsvo, ichipa basa ravo. Kuwanda nephrons mune zvose itsvo ndiyo mamiriyoni 3-4. The nephron rinoumbwa vascular glomeruli, renal tubules uye capsules.

The nemamiriro itsvo uye nephron

Kune mhando mbiri nephrons - zvachero kana cortical uye yakadzika kana juxtaglomerular. The juxtaglomerular glomeruli iri loop refu Henle, iyo inoguma iri renal papilla. Glomerular rirambe richibvira endothelium akafukidzwa pores kuburikidza iyo ultrafiltration weti. Capillaries vane glomeruli bhesimendi membrane. masero Epithelial akafanana Mapedhi pamwe yakatesvera panyanga dzacho kuti vafukidze kunze rirambe richibvira. Pezvakaitwa dzinoumba zimba Kamudzira, ine yakaoma basa mamwe mupise weti uye itsvo mabasa.

Vascular renal glomerulus vakaumba capillaries, izvo vanoparadzaniswa nokukonzera midziyo Outlet rirambe richibvira arterioles uye yechipiri afoot zvitengeswa tubule. The juxtaglomerular midziyo chakabatikana mumasero anokosha kuti pave renin. fuma iyi ave achishingaira munyaya kwerunyararo BP siyana. Most tubule iri muna medulla kuti itsvo. Nekuti zvinoyerera mudziyo uri rakatetepa zvikuru inotungamira, ari glomeruli, pazera yakakwirira kumanikidzwa (anenge 60 mm HG) uye mupise kunoitika yose ropa runoyerera. The kutanga Chikamu tubule glomerular Kamudzira marudzi akapoteredza Shymlanskaya-Bowman. A bhora ane Kamudzira rinonzi renal kana Malpighian corpuscle.

Urinary tubule ane kunzwisisa maumbirwo. Straight zvikamu tubules, loop pamusoro Henle uye sbornve Urinary chubhu riri medulla, uye ichitenderera tubular zvikamu yaiva pedyo kuti glomeruli uye chimiro navo itsvo cortex.

Itsvo mamiriro chendangariro chekuenderera mberi nokushanda. Muchikamu ichi glomerular mabasa, uye mumwe - zviri pa zororo. All ropa riri mumuviri womunhu, runoyerera kuburikidza itsvo mukati awa rimwe. For Sutoki ichipfuura itsvo 1500-2000 litres ropa. Rinoumba zvinhu weti kunyanya uchagumburwa renal ropa, asi vamwe vari akaumba zvakananga itsvo, semuenzaniso, amoniya uye gipurovaya acid.

Tava akaongororwa sechivako itsvo - chikuru nhengo nezvezvimwe zvinetso zvedundira, ichipa excretion pakati metabolic zvinhu nekusazvidzora fluid uyewo yokudzora dzomunyika homeostasis womunhu muviri.
