Insulin thiab glucagon yog cov tshuaj hormones zais los ntawm cov islet cells hauv txiav txiav . Lawv ob leeg tau zais rau hauv cov lus teb rau cov ntshav qab zib, tab sis nyob rau qhov tsis sib xws! Insulin feem ntau secreted los ntawm tus beta hlwb (ib hom islet cell) ntawm txiav txiav.
Tsis tas li ntawd, lub hom phiaj ntawm cov hlwb ntawm insulin thiab glucagon yog dab tsi?
Cov lub hom phiaj ntawm cov tshuaj insulin yog daim siab, nqaij, thiab cov nqaij adipose. 4. Hauv lub xeev yoo mov, glucagon tswj kev txav ntawm cov khoom noj uas khaws cia rau hauv cov ntshav. Lub siab yog lub ntsiab physiological lub hom phiaj ntawm glucagon.
cov cell twg tsim cov tshuaj insulin hauv lub txiav? Pancreatic islets tsev peb loj ntawm tes hom, txhua tus uas tsim tawm Lwm yam khoom endocrine: Alpha hlwb (A hlwb ) tso cov tshuaj hormone glucagon. Beta hlwb (B hlwb ) tsim cov tshuaj insulin thiab yog cov nplua nuj tshaj plaws ntawm cov islet hlwb.
Ib yam li ib tus yuav nug, yuav ua li cas thiaj li tso cov tshuaj insulin thiab glucagon tswj hwm?
Pancreatic secretes insulin thiab glucagon . Ob qho tshuaj hormones ua haujlwm sib npaug los ua lub luag haujlwm tseem ceeb hauv tswj ntshav qab zib. Thaum cov ntshav qab zib ntau dhau, cov txiav ua zais zais ntau cov tshuaj insulin . Thaum cov piam thaj hauv cov ntshav poob qis, cov txiav txiav tawm glucagon tsa lawv.
Dab tsi ua rau insulin?
Cov tshuaj insulin yog ib yam tshuaj uas ua los ntawm cov txiav ua rau lub cev tso cai rau koj lub cev siv cov piam thaj (glucose) los ntawm cov carbohydrates hauv cov zaub mov uas koj noj kom muaj zog lossis khaws cov piam thaj rau yav tom ntej. Cov tshuaj insulin pab ua kom koj cov ntshav qab zib tsis txhob siab dhau (hyperglycemia) lossis qis heev (hypoglycemia).

Cov cell twg tsim cov tshuaj interferons?
Hom I interferon (IFN-alpha thiab IFN-beta) yog zais los ntawm cov kab mob sib kis hauv lub cev thaum hom II, tiv thaiv kab mob lossis gamma interferon (IFN-gamma) feem ntau yog zais los ntawm T cells, cov neeg tua neeg (NK) hlwb thiab macrophages
Cov ntsiav tshuaj daim ntawv twg muaj cov txheej tshwj xeeb uas tiv thaiv lub plab acid thiab ua rau cov tshuaj yaj hauv cov hnyuv?
Cov txheej txheej enteric yog cov txheej txheem polymer siv rau ntawm cov tshuaj hauv qhov ncauj uas tiv thaiv nws txoj kev tawg lossis tsis tawg hauv ib puag ncig lub plab
Cov kab mob hauv qhov ncauj dab tsi metabolize sucrose tsim cov nplaum glucans thiab tsim cov quav hniav?
GTF yog qhov tseem ceeb enzyme uas catalyzes sucrose rau nplaum glucans thiab pab txhawb kev tsim cov hniav plaque nyob rau hauv uas lub tsub zuj zuj ntawm metabolic acids uas ua los ntawm cov kab mob colonies ua rau lub zos demineralization ntawm cov enamel nto (Loesche, 1986)
Thaum sib xyaw cov tshuaj insulin luv luv thiab cov tshuaj insulin nruab nrab hauv tib lub koob txhaj tshuaj insulin yuav tsum tau kos ua ntej?
Thaum koj sib xyaw cov tshuaj insulin tsis tu ncua nrog lwm hom insulin, ib txwm kos cov insulin tsis tu ncua rau hauv rab koob ua ntej. Thaum koj sib xyaw ob hom tshuaj insulin uas tsis yog cov tshuaj insulin ib txwm, nws tsis muaj teeb meem dab tsi xaj koj coj lawv mus rau hauv lub raj mis
Dab tsi yog qhov sib txawv ntawm cov tshuaj yuav tshuaj thiab cov lus nug ntawm cov tshuaj hauv khw muag tshuaj?
Cov tshuaj yuav yog cov tshuaj uas xav kom kws kho mob sau tseg kom muab faib tawm. Hauv lub txee, cov tshuaj yog cov tshuaj zoo li Advil lossis Tylenol uas koj tsis xav tau kws kho mob sau tseg los yuav. Qhov sib txawv tseem ceeb ntawm ob yog tias koj yuav tsum muaj daim ntawv yuav tshuaj tshuaj yog tias nws yog tshuaj yuav tshuaj
