Nezindlala Exocrine kwabantu

Kubantu, kukhona eziningi izinhlelo zokulawula, ukuqinisekisa ukusebenza evamile umzimba. Lezi izinhlelo, ikakhulukazi, kufanele kufake kwangaphakathi futhi yangaphandle ndlala uketshezi.

Licasulwe ibhalansi emzimbeni izinto kalula. Ochwepheshe batusa ukuba ugweme izinto okubangela isimo sokungalingani.

Exocrine nezindlala (eccrine) enze ezahlukene Ukukhetha agents imvelo yangaphakathi kanye ebusweni nomzimba. Bakha i nephunga ngabanye kanye ethize. Ngaphezu kwalokho, exocrine nezindlala ukunikeza ukuvikelwa Ukungena emzimbeni nezilwanyana ezincane eziyingozi. osenyameni yabo (imfihlo) has mikostaticheskim futhi isinyathelo amagciwane.

Exocrine uketshezi (ngamathe, izinyembezi, umjuluko, ubisi, ubulili) zinengxenye ukulawulwa intraspecific futhi interspecific ubudlelwano. Lokhu kungenxa kakhulu ngenxa yokuthi osenyameni yabo sinikezwe umsebenzi noma ulwazi umzimba ukuthonya ezizungezile eziphilayo zangaphandle.

Emlonyeni, zikhona ezincane nezinkulu salivary nezindlala we uketshezi zangaphandle. Amapayipi yabo ukuvula ku le ngalo ingaphakathi ngomlomo. nezindlala Small ise submucosa noma isikhwehlela mkhulu. Ngokuhambisana ilungiselelo isehlane lingual, palatal, izinyo lomhlathi, labial. Kuya ngemvelo sokukhishwa kwabo, zihlukaniswe lwamafinyila, serous futhi edidayo. Budebuduze wabo indlala yegilo of uketshezi yangaphakathi. Iqoqa futhi bukhipha ama-hormone i-iodine-equkethe.

Elikhulu salivary nezindlala ngokuthi izitho abhanqiwe ukuthi zitholakala ngaphandle ngalo ingaphakathi ngomlomo. Lezi zihlanganisa sublingual, submandibular futhi parotid.

Ingxube ahlukaniswa salivary nezindlala ngokuthi ngamathe. izinqubo Secretory zenzeka phakathi kwama-hormone sishintsha umzimba (at nambili - kweminyaka eyishumi nane ubudala) kuyinto okukhulu kakhulu.

nezindlala mammary kuthiwa (ekuqaleni) Ushintshe umjuluko nezindlala kwesikhumba wathelisa ngesonto lesithupha noma lesikhombisa. Ekuqaleni, Babukeka njengezihlahla ezimbili lwezimpawu we epidermis. Ngemva kwalokho sebeqala yakha "ubisi izindawo".

Ngaphambi kwesikhathi zokuthomba amabele amantombazane kukhona imiqumbe. amagatsha wanabalalisela kwenzeka kokubili abafana namantombazane. Lapho kuqala zokuba umuntu omdala kukhona okushintshako e izinga yentuthuko nezindlala mammary. Ngo abafana, isilinganiso sabo ukuthuthukiswa kubambezela, ame ngokuphelele. Ngo amantombazane, ukuthuthukiswa yanda. Ekupheleni kwesigaba kwakheka nokuqala kwenkathi yokuqala. Nokho, kufanele kuphawulwe ukuthi nomdlavuza wamabele kwabesifazane uyaqhubeka ukuthuthukisa kuze sokukhulelwa. Ukwakheka kwabo kokugcina kwenzeka ngesikhathi lactation.

Luhlelo lolukhulu lwa kakhulu we ndlala wokugaya ukudla of the human iyona isibindi. Isisindo wakhe (umuntu omdala) - kusukela omunye khilogremu nenxenye. Ngaphezu kwalokho, isibindi ohilelekile carbohydrate, amavithamini, amaprotheni namafutha umzimba, ovikelayo, chologenic kanye neminye imisebenzi. Lapho kwengane esiswini , lokhu umzimba namanje futhi igazi-ukwakha.

I nezindlala umjuluko kwesikhumba ukukhiqiza umjuluko. Ababandakanyeka thermoregulation, ukwakha iphunga ngabanye. Mela lezi nezindlala tube elula nge eligoqiwe ekupheleni izingxenye. In ngamunye nezindlala umjuluko babe ingxenye ukuphela (umzimba), ujuluke imbobo. Kugcine ngezinye izikhathi ivula kwangaphandle.

Sweat nezindlala kukhona ukungezwani phakathi ukubaluleka tekusebentisa izici morphological, kanye nentuthuko. Basuke etholakala izicubu ongama (zezinzwa). Ngokwesilinganiso, umuntu has mayelana ezimbili - ezintathu eziyisigidi nesigamu umjuluko nezindlala. ukuthuthukiswa yabo morphological usuphothuliwe ngo yiminyaka eyisikhombisa.

nezindlala Sebaceous ukufinyelela Selilonke at nokuthomba. Cishe bonke abahlangene nezinwele. Ezindaweni lapho kungekho ukukhula izinwele, izindlala sebaceous amanga bebodwa. osenyameni wabo - amafutha - esetshenziswa gcoba izinwele kanye isikhumba.
