Glands Exocrine yabantu

Xa abantu, kukho inani lwezi zixokelelwano zolawulo, ukuqinisekisa ukusebenza eqhelekileyo umzimba. Ezi nkqubo, ingakumbi, kufuneka ibandakanye yangaphakathi langaphandle gland secretion.

Ubudlelwane bezinto emzimbeni kakhulu lula. Iingcali Siyaleza ukuphepha izinto ebangela ukungalingani.

amadlala Exocrine (eccrine) aphathe arhente ezahlukeneyo ukhetho kwi -bume lwangaphakathi kunye umphezulu umzimba. Zakha nevumba ngamnye ethile. Ngaphezu koko, amadlala exocrine Laliwukhusela sokungena kwi emzimbeni ezincinane eziyingozi. ekubhobhozeni yabo (ngasese) iye mikostaticheskim kunye nesenzo bactericidal.

netuwa Exocrine (ngamathe, iinyembezi, ukubila, ubisi, sex) bazibandakanye umthetho intraspecific kunye interspecific ulwalamano. Oku kubangelwa ubukhulu becala ngenxa yenyaniso yokuba ekubhobhozeni lwabo sinikezwe umsebenzi okanye ulwazi pathways ukuphembelela ezingqonge eziphilayo zangaphandle.

Emlonyeni, kukho incinci kunye, inkulu amathe amadlala of secretion lwangaphandle. imibhobho vula kwi kwisisu ngomlomo. glands encinane kwi submucosa okanye yencindi ziyatyeba. Ukungqinelana ilungiselelo bodwa zeelwimi, palatal, izinyo, labial. Kuxhomekeka kuhlobo obhobhozayo zabo, yohlulwe uxakaxa, serous kunye exutyiweyo. Hayi kude kuzo esinobubovu lengqula of secretion lwangaphakathi. It uqokelela kwaye ikhupha hormone ayodini-equlethe.

kwamadlala amathe enkulu ebizwa ngokuba amalungu bafundelane ngezibini, ukuba ibekwe ngaphandle kwisisu ngomlomo. Ezi ziquka sublingual, submandibular kunye parotid.

Lo mxube siyahlukana kwamadlala amathe kuthiwa namathe. iinkqubo Secretory zenzeke ngexesha kwamadlala utshintsho emzimbeni (at elinambini - kweminyaka elishumi elinesine ubudala) yeyona kakhulu.

glands Mammary ukuba (ekuqaleni) modified amadlala ukubila ulusu, wayibeka phezu kwiveki yesithandathu okanye yesixhenxe. Ekuqaleni, bakhangeleka ngathi amatywina ezimbini sangaphandle. Kamva niqalise ukwakha "iindawo ubisi".

Phambi kokuba isithuba amabele lokufikisa mantombazana aleleyo. amasebe ukwanda yenzeka nobudala. Xa kuqala ngumntu kukho utshintsho ngokukhawuleza ekujongeni ireyithi uphuhliso amadlala mammary. Xa amakhwenkwe, izinga yophuhliso lingancipha, ngoko ime ngokupheleleyo. Xa amantombazana, uphuhliso kwandiswa. icandelo ekupheleni Bakha ekuqaleni kwethuba lokuqala. Nakuba kunjalo, kufanele kuqatshelwe ukuba umhlaza webele kwabasetyhini uyaqhubeka ukuphuhlisa de lokukhulelwa. lasungulwa wokugqibela kwenzeka ngexesha zisanyisa.

Eyona inkulu ye esinobubovu zokwetyisa ye obuntu isibindi. Ubunzima (abadala) yakhe - ukusuka kwelinye ukuya eekhilogremu enye enesiqingatha. Ukongeza, isibindi ukubandakanyeka carbohydrate, iivithamini, iiproteins kunye namanqatha ukutya, oko zokuzikhusela, chologenic kunye neminye imisebenzi. Xa Palsy , le umzimba kwaye negazi-forming.

Kwamadlala ukubila ulusu ukuvelisa ukubila. Bona inxaxheba thermoregulation, kusenziwa ivumba ngamnye. Ubonise ezi luqinisekisa tube elula kunye nezahlulo ekupheleni esongiweyo. Kwimeko nganye kwezi amadlala umbilo kuba isiphelo isabelo (emzimbeni), ilima duct. maxa wambi wokugqibela ivula ngaphandle.

amadlala xhopho ukungaboni kwixabiso ezisebenzayo kunye neempawu morphological, ngokunjalo nophuhliso. Bona ise inyama ongama (nokuqina). Kwi-avareji, umntu malunga ezimbini - amadlala ezintathu nesiqingatha sesigidi ukubila. uphuhliso lwabo morphological igqityiwe kweminyaka esixhenxe.

glands Sebaceous ifikelele incopho yayo ukufikisa. Phantse zonke kubo ezinxulumene ne iinwele. Kwiindawo apho kungekho kukhula iinwele, amadlala sebaceous kulala ngokwabo. ekubhobhozeni yabo - amanqatha - esetyenziswayo nokuthambisa isixhobo iinwele kunye nesikhumba. I-avareji ngemihla esimelela malunga namashumi amabini grams okunamafutha.
