Ngokukodwa, emzimbeni womntu ngamnye kukho iqumrhu elibini elibizwa ngokuba yi-ureter. Ngendlela yokubonakala, ityhuni engenalutho, ubude bayo bungengaphezulu kwe-30 cm, kunye nobubanzi - ukusuka kwi-4 ukuya kuma-7 mm. Kule nqaku siza kukuxelela ukuba kutheni i-ureters iyadingeka, yintoni isakhiwo sayo, kwaye yintoni eyenziwa le mzimba.
Ulwakhiwo lomntu okhulayo kumabhinqa namadoda
Ureters emzimbeni wabantu bobabini bavela kwi-renal pelvis. Ukongezelela, le mibhobho ihla emva kwe-peritoneum ize ifike eludongeni lwesibindi , esingaphumelela kuyo.
Udonga lwe-ureter ngalinye lunamaqela amathathu:
- igobolondo yangaphandle, equkethe izicubu ezinxibelelwano;
- ungqimba lwe-muscular;
- i-membrane ye-mucous egubungela i-ureter ngaphakathi.
Ubuninzi be-ureters luxabiso oluthile kwaye luyahlukahluka kakhulu kwiindawo ezahlukeneyo. Ngoko, ngokuqhelekileyo umntu ngamnye unobuncwane obuninzi be-anatomical kule nxalenye elandelayo:
- kwindawo yenguqu ye-renal pelvis kwi-ureter;
- phambi kokuphuma kwe-ureter kwi-pelvis encinci;
- Kwezinye iindawo kwi-pelvis encinci okanye kunye nobude bayo bonke;
- Ngaphambi kokungena kwe-ureter nganye kwi-bladder.
Ubude beli lungu kubantu abahlukeneyo banokuhluka, kuxhomekeke kwisini, ubudala kunye neempawu zomntu ngamnye.
Ngaloo ndlela, urereter wesifazane ngokuqhelekileyo u-20-25 mm mfutshane kunendoda. Kwi-pelvis encinci kumabhinqa amahle le bhubhu iyanyanzelekile ukuba igqoke izitho zangasini zangaphakathi zesondo, ngoko ke inenkqubela eyahlukileyo.
Ekuqaleni, i-female ureters idlula ngaphaya komda we-ovaries, kwaye emva kwesiseko somlenze omkhulu we-uterus. Ukuqhubela phambili, ezi ziphulo zihamba kunye ne-oblique pass in the bladder kwiindawo ezikufutshane zecala, ngelixa kudibanisa i-sphincter ye-muscular.
Umsebenzi we-ureter emzimbeni womntu
Umsebenzi oyintloko owenzayo uhambo lokuthutha umchamo ukusuka kwi-pelal pelvin ukuya kwisibilini. Ubuninzi bomgca we-muscle eludongeni lwalesi siqumrhu luvumela ukuba lutshintshe rhoqo ububanzi bayo ngaphantsi koxinzelelo lomchamo olugeleza ngaphakathi kwisigxina sangaphakathi sebhubhu, ngenxa yoko "kuqhutyelwa" ngaphakathi. Ngaloo ndlela, umchamo awukwazi ukubuyela emuva, njengenxalenye yesikhombiso ngaphakathi kwesikhumba esisebenza njengevinive kunye nefusi.
