Hauv txoj kev no, dab tsi yog kev ua haujlwm endocrine ntawm cov txiav txiav?
Endocrine Function: Cov kab mob endocrine ntawm tus txiav txiav muaj cov islet cells (islets of Langerhans) uas tsim thiab tso tawm tseem ceeb tshuaj hormones ncaj qha rau hauv cov ntshav. Ob ntawm lub cev tseem ceeb tshuaj hormones yog insulin, uas ua rau txo cov ntshav qab zib, thiab glucagon, uas ua rau nce ntshav qab zib.

Raws li cov qog endocrine, nws ua haujlwm feem ntau los tswj cov ntshav qab zib, zais cov tshuaj insulin, glucagon, somatostatin, thiab txiav polypeptide.
Tib neeg tseem nug, dab tsi yog cov qog endocrine ntawm tus txiav?
Cov islets ntawm Langerhans yog cov endocrine (endo = hauv) cov hlwb ntawm cov txiav uas tsim thiab zais cov tshuaj hormones xws li insulin thiab glucagon rau hauv cov hlab ntshav. Cov txiav cov tshuaj hormones, insulin thiab glucagon, ua haujlwm ua ke kom tswj tau qib qab zib (piam thaj) hauv cov ntshav.
Vim li cas tus txiav txiav hu ua exo endocrine gland?
Cov qog endocrine yog cov qog uas tso lawv cov zais cia ncaj qha rau hauv cov ntshav uas nqa nws mus rau qhov chaw. Txij li thaum pancreas secretes ob qho tib si digestive kua txiv thiab cov tshuaj hormones thiab muaj exocrine thiab endocrine qhov chaw, nws yog lub npe hu ua ib exo ua - endocrine qog.
