Glucagon yog ib yam tshuaj uas koom nrog hauv kev tswj cov ntshav qab zib (glucose) qib. Cov glucagon - zais cia alpha cells nyob ib puag ncig cov insulin- zais cia beta hlwb, uas qhia txog kev sib raug zoo ntawm ob qho tshuaj hormones. Glucagon lub luag haujlwm hauv lub cev yog txhawm rau tiv thaiv cov ntshav qabzib poob qis dhau.
Ib yam li ntawd, nws tau nug, dab tsi ua rau lub zais zais ntawm glucagon?
Glucagon secretion yog txhawb nqa los ntawm kev noj cov protein, los ntawm cov ntshav qabzib tsawg (hypoglycemia), thiab kev tawm dag zog. Nws raug txwv los ntawm kev noj cov carbohydrates, cov txiaj ntsig uas tuaj yeem cuam tshuam los ntawm qhov nce ntawm cov ntshav qabzib ntau thiab insulin zais zis.
Vim li cas glucagon txhawb nqa los ntawm cov amino acids? Ib qho kev nce hauv amino acid Kev sib txuas nrog pancreatic A-hlwb yog ua raws li a kev txhawb nqa ntawm glucagon tso tawm. Thaum B-cells ua haujlwm tsis zoo thiab teb ua ke rau qhov amino acid , cov piam thaj hloov pauv tau nce ntxiv thiab cov ntshav glycose concentration tseem nyob li qub.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi tshwm sim nce ntxiv ntawm glucagon thiab insulin tso tawm?
Ob leeg glucagon thiab insulin tso tawm yog txhawb nqa los ntawm kev noj cov amino acids, xav tias yuav txo qis hypoglycemia yog tias noj cov protein ntshiab. Hauv cov tib neeg ib txwm muaj, glucagon tso tawm yog txhawb los ntawm hypoglycemia, cov txheej txheem tiv thaiv kom tswj ntshav qabzib concentration homeostasis.
Puas yog insulin txo qis glucagon secretion?
Hauv kev xaus, cov ntaub ntawv no qhia tias cov tshuaj insulin rau nws suppresses glucagon tso tawm thaum lub sijhawm euglycemia thiab a txo hauv cov tshuaj insulin per se, nyob rau hauv kev hais kwv txhiaj nrog tsawg qabzib, taw qhia ib tug nce nyob rau hauv glucagon tso tawm thaum lub sij hawm hypoglycemia.

Dab tsi yog lub zais zis zais zis qhia?
Abdominal ultrasound: Ultrasound tsim cov duab ntawm lub zais zis thiab cov kua tsib ducts. Nws qhia pom cov tsos mob ntawm tus kab mob los yog qhia tias muaj qhov txhaws ntawm cov kua tsib ntws. Ultrasound yog qhov kev kuaj pom feem ntau ua los ntsuas qhov txawv txav ntawm lub zais zis
Lub zais pa sawv cev dab tsi lub raj mis sawv cev yog lub zais pa sab hauv lossis sab nraum lub raj mis?
Yam twg ntawm tus qauv lub ntsws sawv cev rau lub ntsws, kab noj hauv siab, tav tav, thiab daim diaphragm? (Lub zais pa me me sab hauv lub raj mis yog lub ntsws
Dab tsi yog cov enzymes ua rau lub zais zis zais?
Bile yog lub zog enzyme uas pab txhawm rau zom cov rog. Thaum cov zaub mov koj noj muaj roj, lub plab thiab duodenum zais ib yam khoom uas txhawb lub zais zis kom sib cog lus, yog li ua rau cov kua tsib nkag mus rau hauv txoj hnyuv. Bile emulsifies cov rog, ua rau nws muaj zog rau kev tsim khoom
Peb yog vim li cas vim li cas lub cell faib?
Nov yog cov laj thawj vim li cas cov cell faib. Vim li cas 1: Mitosis thiab meiosis yog cov txheej txheem tseem ceeb. Vim li cas 2: Cell faib rau lub cev kev loj hlob thiab kev loj hlob. Yog vim li cas 3: Cov cell faib los kho peb lub cev. Kev faib tawm ntawm tes yog qhov tseem ceeb rau peb lub cev kev loj hlob thiab kev loj hlob
Vim li cas koj thiaj nyob tsis muaj lub zais zis?
Nyob tsis muaj lub zais zis Koj tuaj yeem ua lub neej zoo ib yam tsis muaj lub zais zis. Koj lub siab tseem yuav ua kom cov kua tsib txaus los zom koj cov zaub mov, tab sis tsis txhob khaws cia rau hauv lub zais zis, nws ntws mus tas li rau hauv koj lub plab zom mov
