Chikafu

Sirasi iyi inhengo isina kumira yehutano hwevanhu. Inowanikwa zvakananga mumakona emakona maduku, kubva kumashure pakatarisana nekutaura kwemafupa. Funga nezvekugadzirwa kwezvinhu izvi zvakanyanya, uye isu tichatumidza basa guru rekanyara.

Muviri uyu unoshanda sei kuvanhu?

Chirwere chinenge chiine shanduko imwechete, zvose varume nevakadzi. Zvisinei, mune zvepabonde zvakasimba pakarepo mushure mechidzitiro ndiko rectum, iyo inobatana nayo. Madzimai kumashure kweiyo chiremera chinonzi vagin. Inofanirawo kutaurwa kuti madzimai ane urogenital diaphragm pasi pemukaka, uye prostate gland mune varume.

Muchimiro chekunze chechidimbu, chiitiko chekuparadzanisa nzvimbo yepasi, yepashure uye yekusimudza. Panguva imwe chete, nekuda kwezvinhu zvayo zvemaatomical, chikamu chepamusoro chechirongwa chinonyanya kushandiswa kupfuura chepasi. iyo yekupedzisira inogadziriswa nemishamba. Apo bharadhi izere nomuguta, rusvingo rwaro rwepamusoro hunomuka uye runofamba pamusoro pe pubis. Panguva imwecheteyo, peritoneum inomutswa, uye chidimbu chinoshandura chimiro chayo uye chinofanana nedhi guru.

Icho chiri pasi, chikamu chechidimbu, chinonzi pasi, chinotarisana uye chinodzoka maererano nechepamusoro. Chikamu chepakati chechiganda ichi, chinonzi mutumbi, zvishoma nezvishoma chichienda kumadziro emadziro emukati, chinoumba icho chinonzi chidimbu chechidimbu. Muchikamu chepakati pezasi pane zvikwiriso zvitatu: 2 miromo yemakwere uye chechitatu inonzi urethra.

Tichifunga nezvekugadzirwa kwechifukidzo chevanhu, munhu haagoni kubatsira kutaura kuti masvingo aro ndeapi. Kunze kwavakafukidzwa nekamu membrane, iyo iyo submucosa iripo. Inotevera nheyo ndeye musuru uye serosa. Muchiitiko ichi, mucous surface yakazara ne epithelium yemazuva ano, iyo inokonzera izvo zvinonzi kudanda. Izvo zviri pamari yake, ivhu remuviri uyu, rinogona kuwedzera kazhinji.

Mutsara wemisungo yegoni inomiririrwa nerefu refu, chitenderera uye mukati-katikati-oblique-longitudinal yezviputi zvinotapira, izvo zvakanyatsobatanidzwa. Muchiitiko ichi, nzvimbo yepakati munharaunda yemutsipa wechipfuva (iyo chikamu apo kuderera kwayo kunowanikwa) kwakapoteredza kuvhura kwemukati kwemukati urethra mukati mukati me sphincter. Icho chikamu chinokonzera kuchengetedza urin mukati memukaka.

Kana tichienzanisa chimiro chechirwere mumadzimai nevarume, zvakakosha kuziva zvinhu zvinotevera zvinotevera:

• mune varume iyo yakakwirira mumatavi maduku, mune vakadzi iri pasi;
• mumadzimai - pamberi pemukadzi nemadzimai, mune varume pakati pe pubic bone uye rectum;
• kureba kwechikadzi urethra - 3-4 cm, murume - anenge 20 cm.

Chii chinonzi chivharo?

Pasinei neurongwa hwaro huri nyore, muviri uyu unotora basa rinokosha mumuviri womunhu. Kubva pane chimiro chebhanyi, unogona kutumidza mabasa ayo makuru uye chinangwa. Pakati pavo pane:

• reservoir;
• kubuda.

Saka, yekutanga ndeyokuunganidza nekuchengetedza urini. Zvinonzwisisika kuti mavhareji emagetsi ekugadzirwa kwechirongwa ichi 200-400 mami (nekuda kwekutambanudzwa kwemasvingo emuti, inopindira zvikuru zvikuru). Inofanirawo kuonekwa kuti kune vanhu vakwegura nekuda kwekuderera kwemaviri echisimba chechivharo, inzwi racho rinowedzera.

Basa rekubudiswa kwechirongwa rinoitwa nekuda kwesangano rechibvumirano chemishupa yemisumbu yechipfuva, uye zvakare semugumisiro wemagumisiro anotsamwisa pama mechanoreceptors e-urethra.

Uyewo pakati pebasa rinogona kunzi kusabatanidzwa kwemuviri musinganzwisisiki mukuchengetedza kusingaperi kwemamiriro ekunze emuviri, nekubvisa zvigadzirwa zvemetabolism.
