Momwe Dongosolo la Endocrine Limayendetsera Kagayidwe ka Metabolism
Kagayidwe kachakudya ndi mndandanda wa zinthu zomwe zimachitika m'thupi zomwe zimathandiza maselo kupeza mphamvu, kumanga ndi kukonza minofu, komanso kuchita ntchito zina zofunika kwambiri. Dongosolo la endocrine limagwira ntchito yofunika kwambiri pankhaniyi potulutsa mahomoni omwe amawongolera mbali zosiyanasiyana za kagayidwe kachakudya. M'nkhaniyi, tikambirana momwe dongosolo la endocrine limagwirira ntchito komanso momwe mahomoni omwe limapanga amawongolera kagayidwe kachakudya.
Chiyambi cha Dongosolo la Endocrine
Dongosolo la endocrine limapangidwa ndi tiziwalo ndi minofu yomwe imapanga mahomoni. Tizilombo tating'onoting'ono timeneti tikuphatikizapo hypothalamus, pituitary gland, thyroid gland, parathyroid glands, adrenal glands, kapamba, mazira mwa akazi, ndi ma testes mwa amuna. Chilichonse mwa tizilomboti chimapanga mahomoni enaake omwe amatulutsidwa mwachindunji m'magazi kuti akafike ku maselo kapena ziwalo zomwe akufuna.
Mahomoni amagwira ntchito ngati mankhwala omwe amawongolera ntchito zambiri za thupi, kuphatikizapo kukula ndi chitukuko, kagayidwe ka mphamvu, ntchito yogonana, kubereka, kugona, ndi malingaliro.
Kulamulira kwa Kagayidwe ka Endocrine System
Chithokomiro ndi Thyroxine
Chimodzi mwa tiziwalo timene timathandiza kwambiri pakulamulira kagayidwe ka thupi ndi chithokomiro. Chithokomirochi chili m'khosi ndipo chimapanga mahomoni a chithokomiro, omwe ndi thyroxine (T4) ndi triiodothyronine (T3).
Mahomoni a chithokomiro amalimbikitsa mphamvu ya kagayidwe kachakudya (BMR), kuchuluka kwa mphamvu zomwe thupi limafunikira popuma kuti ligwire ntchito zoyambira monga kupuma ndi kuyenda kwa magazi. Thyroxine imawonjezera mphamvu ya kagayidwe kachakudya mwa kuwonjezera mpweya womwe maselo amthupi amagwiritsa ntchito komanso kuyambitsa kutentha. Zotsatira zake, anthu omwe ali ndi mahomoni ambiri a chithokomiro nthawi zambiri amakhala ndi mphamvu zambiri komanso kagayidwe kachakudya, pomwe omwe ali ndi mahomoni ochepa a chithokomiro nthawi zambiri amakhala ndi kagayidwe kachakudya pang'onopang'ono ndipo amatha kunenepa.
Pancreas ndi Insulin
Pancreas ndi chiwalo china chofunikira chomwe chimagwira ntchito yolamulira kagayidwe kachakudya, makamaka kagayidwe ka shuga m'thupi. Chimapanga mahomoni otchedwa insulin ndi glucagon. Insulin imatulutsidwa shuga m'magazi akakwera, mwachitsanzo mutatha kudya. Insulin imathandiza maselo kutenga shuga m'magazi kuti igwiritsidwe ntchito ngati mphamvu kapena kusungidwa ngati glycogen m'chiwindi ndi minofu kuti igwiritsidwe ntchito pambuyo pake.
Makamaka, insulin imagwira ntchito powonjezera kulowa kwa shuga m'maselo, zomwe zimathandiza kuti shuga alowe m'maselo. Motero, insulin imachepetsa shuga m'magazi. Anthu omwe ali ndi matenda a shuga amtundu woyamba, omwe sapanga insulin yokwanira, kapena matenda a shuga amtundu wachiwiri, omwe sagwira ntchito ndi insulin, amavutika kuwongolera kuchuluka kwa shuga m'magazi mwawo, zomwe zingayambitse mavuto osiyanasiyana a kagayidwe kachakudya m'thupi.
Adrenal Glands ndi Cortisol
Ma adrenal glands, omwe ali pamwamba pa impso, amapanga mahomoni osiyanasiyana omwe amakhudza kagayidwe kachakudya. Limodzi mwa mahomoni akuluakulu omwe amapangidwa ndi cortisol, lomwe limatulutsidwa chifukwa cha kupsinjika maganizo komanso kuchuluka kwa shuga m'magazi.
Cortisol imathandiza kukweza shuga m'magazi kudzera mu njira yotchedwa gluconeogenesis, momwe thupi limapanga shuga kuchokera ku mapuloteni ndi mafuta. Kuphatikiza apo, cortisol imayang'anira kagayidwe ka mafuta ndi mapuloteni. Mwachitsanzo, cortisol imawonjezera kuwonongeka kwa mapuloteni m'minofu kuti apange ma amino acid , omwe amatha kusinthidwa kukhala shuga.
Hypothalamus ndi Pituitary Gland
Hypothalamus ndi pituitary gland muubongo zimakhala malo olumikizirana a dongosolo la endocrine. Hypothalamus imatumiza zizindikiro ku pituitary gland kuti itulutse kapena kuletsa mahomoni ena, omwe kenako amawongolera ma endocrine gland ena. Mwachitsanzo, hypothalamus imatulutsa thyrotropin-releasing hormone (TRH), yomwe imalimbikitsa pituitary gland kuti itulutse thyroid-stimulating hormone (TSH). Kenako TSH imagwira ntchito pa thyroid gland kuti ilimbikitse kupanga mahomoni a thyroid.
Kuphatikiza apo, hypothalamus imayang'aniranso mahomoni otulutsa corticotropin (CRH), omwe amalimbikitsa pituitary gland kutulutsa adrenocorticotropic hormone (ACTH), omwe amalimbikitsa adrenal glands kuti apange cortisol. Njira yobwezera magazi iyi imatsimikizira kuti kuchuluka kwa mahomoni m'magazi kumakhala koyenera komanso koyenera zosowa za thupi.
Hormone Yokula
Homoni ya kukula (GH) imapangidwa ndi pituitary gland ndipo imakhudza kwambiri kukula ndi chitukuko , komanso kagayidwe kachakudya. GH imalimbikitsa kukula kwa minofu ndi mafupa ndikuwonjezera kusweka kwa mafuta kuti apeze mphamvu. GH imakhalanso ndi zotsatira za anabolic, zomwe zikutanthauza kuti imathandizira kupanga mapuloteni ndi kukula kwa maselo.
Muubwana ndi unyamata, GH ndi yofunika kwambiri pakukula ndi kukula kwa thupi. Kwa akuluakulu, GH imathandiza kusunga minofu ndi mafupa ndipo imathandizanso pakuwongolera kapangidwe ka thupi ndi kagayidwe kachakudya m'thupi.
Mahomoni Ogonana
Mazira a akazi ndi ma testes mwa amuna nawonso amachita gawo pa kagayidwe kachakudya kudzera mu kupanga mahomoni ogonana monga estrogen, progesterone, ndi testosterone. Ma mahomoni awa samangowongolera ntchito yobereka komanso amakhudza kagayidwe kachakudya ka mphamvu.
Kwa akazi, estrogen imathandiza kulamulira kugawa kwa mafuta m'thupi komanso imakhudzanso kukhudzidwa kwa insulin, motero imakhudza kagayidwe ka shuga m'thupi. Progesterone imatha kuwonjezera kutentha kwa thupi ndikukhudza kagayidwe ka shuga.
Mwa amuna, testosterone imalimbikitsa kukula kwa minofu ndi kagayidwe ka mapuloteni, ndipo imawonjezera kutentha kwa mafuta, motero imakhudza kapangidwe ka thupi.
Mahomoni a Leptin ndi Ghrelin
Leptin ndi ghrelin ndi mahomoni opangidwa ndi minofu ya mafuta ndi m'mimba omwe amagwira ntchito yofunika kwambiri pakulamulira chilakolako cha chakudya ndi mphamvu. Leptin imauza ubongo kuti uchepetse chilakolako cha chakudya pamene mafuta akusungidwa mokwanira. Mosiyana ndi zimenezi, ghrelin imawonjezera chilakolako cha chakudya podziwitsa ubongo pamene m'mimba mulibe kanthu.
Kulamulira mahomoni amenewa kungakhudze kulemera kwa thupi ndi kapangidwe ka thupi. Mwachitsanzo, kukana leptin kungayambitse kunenepa kwambiri chifukwa ubongo sulandira chizindikiro choti usiye kudya ngakhale kuti mafuta osungidwa m'thupi ndi okwanira.
Mapeto
Dongosolo la endocrine limagwira ntchito yofunika kwambiri polamulira mbali zonse za kagayidwe kachakudya. Kuyambira kulamulira kuchuluka kwa shuga m'magazi ndi insulin ndi glucagon mpaka kusintha kagayidwe kachakudya ndi mahomoni a chithokomiro, mahomoni aliwonse amagwira ntchito mogwirizana kuti atsimikizire kuti thupi likugwira ntchito bwino. Kusokonezeka kwa magwiridwe antchito a dongosolo la endocrine kungayambitse mavuto osiyanasiyana azaumoyo, kuphatikizapo matenda a shuga, hypothyroidism, ndi metabolic syndrome.
Kumvetsetsa momwe dongosolo la endocrine limayendetsera kagayidwe kachakudya sikuti kokha ndikofunikira kumvetsetsa kagayidwe ka thupi la munthu komanso kumapereka chidziwitso cha momwe njira zamankhwala ndi kusintha kwa moyo zingagwiritsidwire ntchito poyang'anira matenda a kagayidwe kachakudya. Kudzera mu kafukufuku wowonjezereka ndi maphunziro opitilira, titha kukonza njira yathu yopezera thanzi la kagayidwe kachakudya.
