Nerevane nemamiriro nephron

Nephron harisi chete huru marongerwo asiwo dzichipfekeka renal chikwata. Zvakanga pano kuti zvinokosha nzendo paumbwe weti. Saka, mashoko sokuti urongwa nephron, uye chii chinoshanda nayo anoita, achava zvinonakidza chaizvo. Uyezve, hunhu kushanda nephrons anogona kujekesa nuances ari renal hurongwa

The nemamiriro nephron: renal corpuscle

Zvinofadza kuti muna vakura itsvo ane utano munhu ari pakati 1 uye 1,3 bhiriyoni nephrons. Nephron - kushanda uye STRUCTURAL Unit itsvo, chine renal corpuscles uye vanonzi loop pakati Henle.

Hazvibetseri renal corpuscle chinosanganisira Malpighian glomerulus uye Bowman kuti Kamudzira - Shymlanskaya. Nokuti kutanga zvinokosha kuziva kuti bhora zvechokwadi dzakaunganidzwa capillaries duku. Ropa anowana kuburikidza pano prinosnuyu tsinga - vari yakasvinwa plasma. Tsauranisa ropa hwokurara efferent arterioles.

The Kamudzira pamusoro Bowman - Shymlanskaya ine machira maviri - nechinzwano zvekunze. Uye kana rokunze jira chinhu munhuwo chaionekwa squamous epithelium, sechivako jira mukati kodzero yokunyanyofungwa. The menzvimbo Kamudzira chakafukidzwa podocytes - ndivo masero kuti azadzise basa zvimwe firita. Havaoni shuga, amino acids uye zvimwe zvinhu, asi kudzivirira kufamba guru mapuroteni mamorekuru. Saka, muna renal corpuscle vakaumba chikuru weti, inova vakasiyana muplasma chete asipo guru mamorekuru.

Nephron: nemamiriro pamusoro proximal tubule uye loop pakati Henle

Proximal tubule ndiyo sangano iro rinobatanidza renal corpuscle uye loop pamusoro Henle. Inside tubule ane villi, izvo zvinowedzera zvachose nzvimbo dzomunyika lumen, nokudaro kuwedzera apiwa Absorção de Água unongotaura.

Proximal tubule zvakanaka mukati pasi chikamu loop pakati Henle, iyo inozivikanwa nokuva dhayamita duku. The loop iri akatura kupinda medulla apo anokotama kumativi yayo akabatana ne 180 madhigirii uye hunokwira - pano atanga kukwira chikamu Henle kuti loop, iro rine yakakura uye, naizvozvovo, ari dhayamita. Achifumira loop akarara anenge ufanane glomerulus.

The nemamiriro nephron: yacho distal tubules

The achifumira chikamu loop pakati Henle ari cortex achipinda dzinonzi distal convoluted tubule. Achipinda kwaaita bhora uye neVadzidzi kwokunze prinosnoy uye arterioles. Pane ari akaita finite Absorção de Água nezvinovaka muviri. Distal tubule inopfuura muchikamu chokupedzisira nephron, izvo zvinozoita runoyerera kupinda yakaungana chubhu, mutakuri mvura iri pasi renal chiuno.

kupatsanura pakati nephrons

Zvichienderana nzvimbo rakakamurwa mhando huru matatu nephrons:

• cortical nephrons vanoumba anenge 85% of dzinokwana zvose STRUCTURAL dzakabatana vari itsvo. Kazhinji, vari riri rokunze renal cortex, iyo, chokwadi, sezvinoratidzwa nezita ravo. Nephron sechivako ichi mhando siyanei - the loop pamusoro Henle ishoma;
• juxtamedullary nephrons - hurongwa dzakadaro dzinongova pakati uropi uye cortical layer vane refu loop pamusoro Henle kuti inobatsira zvikuru kupinda medulla, dzimwe nguva kusvika mapiramidhi;
• subcapsular nephrons - yakarongeka, izvo akaronga zvakananga pasi Kamudzira.

Zvinogona kucherechedzwa kuti nemamiriro nephron kunoenderana zvizere mabasa ayo.
