QHOV CHAW UA HAUJ LWM ua rau tag nrho UNICELLULAR EXOCRINE GLANDS tsim? Tag nrho cov unicellular exocrine qog secrete protein mucin (uas ua hnoos qeev ntawm kev sib tov nrog dej).

Ib yam nkaus, dab tsi ua rau cov qog nqaij hlav exocrine tsis sib xws?

Exocrine qog secrete lawv cov khoom mus rau ntawm daim tawv nqaij lossis hauv lub cev kab noj hniav. Unicellular exocrine qog ua Qhov no ncaj qha los ntawm exocytosis, thaum multicellular qog thauj lawv cov khoom los ntawm cov kav dej ntawm qhov chaw epithelial. Khoom zais cia los ntawm exocrine qog suav nrog hws, roj, mucous, kua tsib, thiab lwm yam.

Ib yam li ntawd, qhov tseeb ntawm unicellular exocrine qog yog dab tsi? Unicellular exocrine qog suav nrog ib lub xov tooj tshwj xeeb tshwj xeeb rau kev zais cia tawg ntawm lwm qhov tsis-secretory epithelial cells ntawm daim nyias nyias. Lawv tsis muaj ducts, tau kawg, tab sis lawv zais lawv cov khoom ncaj qha rau ntawm qhov chaw dawb ntawm qhib lub cev kab noj hniav thiab yog li, raug txiav txim siab. ua exocrine.

Tsis tas li ntawd, cov qog nqaij hlav qog ua dab tsi?

A qog yog ib pab pawg hlwb hauv tus tsiaj lub cev uas tsim cov tshuaj (xws li cov tshuaj hormones) tso rau hauv cov ntshav (endocrine) qog ) lossis nkag mus rau kab noj hniav hauv lub cev lossis nws sab nrauv (exocrine qog ).

Yuav ua li cas yog multicellular exocrine qog cais?

Multicellular exocrine qog yog cais los ntawm lawv cov duab ntawm secretory qhov chaw thiab los ntawm kev npaj ntawm lawv ducts. A qog nrog ib lub duct yog "yooj yim," whereas a qog nrog ib tug branched duct yog "compound" qog.
