Tsis zoo tswv yim yog ib qho tshuaj tiv thaiv uas ua rau txo qis hauv kev ua haujlwm. Nws tshwm sim los teb rau qee yam kev txhawb siab. Feem ntau nws ua rau kev tso tawm ntawm a lawv kom tsawg; yog li, cov tawm tswv yim nyhav kom ruaj khov lawv . Qhov no tuaj yeem raug hu ua homeostatis, zoo li hauv biology, lossis sib npaug, zoo li hauv tshuab.
Ua qhov no hauv kev txiav txim siab, dab tsi yog qhov piv txwv ntawm cov tswv yim tsis zoo?
Piv txwv ntawm cov txheej txheem uas siv tsis zoo tswv yim loops suav nrog cov tshuab homeostatic, xws li: Thermoregulation (yog tias lub cev hloov pauv kub, cov tswv yim Cov tshuaj insulin txo qis ntshav qabzib thaum qib siab; glucagon nce ntshav qabzib thaum qib qis).
Tsis tas li ntawd, dab tsi ua rau kev tawm tswv yim tsis zoo? Hauv a tsis zoo tswv yim system qee yam, xws li ntshav siab, hloov pauv. Qhov kev hloov no yog kuaj los ntawm lub sensor. Lub sensor xa lus mus rau ib qho chaw sib koom ua ke uas ua rau muaj kev cuam tshuam rau ib qho effector. Lub hlwb yuav ua lub plawv dhia qeeb thiab yog li txo cov ntshav siab.
Los ntawm qhov ntawd, qhov tseem ceeb ntawm kev tawm tswv yim tsis zoo yog dab tsi?
Tsis zoo tswv yim tshwm sim thaum lub kaw lus tsim tawm los txo lossis txo cov txheej txheem uas ua rau cov txheej txheem tsim tawm, uas ua rau cov khoom tso tawm tsawg dua. Feem ntau, tsis zoo tswv yim loops tso cai rau lawv tus kheej stabilize. Tsis zoo tswv yim yog ib qho tseem ceeb tswj tshuab rau lub cev homeostasis.
Cov tswv yim tsis zoo ua haujlwm li cas los tswj lub cev kub?
Kev saib xyuas ntawm homeostasis feem ntau cuam tshuam nrog tsis zoo tawm tswv yim loops . Cov no loops ua los tawm tsam qhov stimulus, lossis cue, uas ua rau lawv. Piv txwv li, yog tias koj lub cev kub siab heev, a negative feedback loop yuav ua kom coj nws rov qab los ntawm qhov teeb tsa, lossis lub hom phiaj tus nqi, ntawm 98.6 ∘ F 98.6, ^circ ext F 98.

Dab tsi yog qhov piv txwv ntawm kev tawm tswv yim tsis zoo hauv cov kab ke endocrine?
Kev tawm tswv yim txog kab mob Endocrine Piv txwv li, koj lub txiav txiav (lub qog tseem ceeb hauv koj cov kab ke endocrine) tso siab rau cov lus tsis zoo los tswj cov ntshav qabzib. Cov lus tsis zoo kuj tseem pab koj yog tias koj cov ntshav qab zib qis dhau. Thaum qhov no tshwm sim, koj lub txiav txiav tawm cov tshuaj sib txawv hu ua glucagon
Thaum ib tus tswv ntiav haujlwm tau txais OSHA qhov kev hais tawm Qhov twg lawv yuav tsum tshaj tawm daim ntawv theej ntawm qhov kev hais tawm?
Yuav Tsum Tau Xa Ntawv Thaum koj tau txais OSHA Daim Ntawv Ceeb Toom, koj yuav tsum tshaj tawm nws (lossis daim ntawv theej ntawm nws) ntawm lossis ze qhov chaw uas txhua qhov kev ua txhaum tshwm sim los ua rau cov neeg ua haujlwm paub txog qhov phom sij uas lawv yuav raug nthuav tawm. Tsab ntawv ceeb toom OSHA yuav tsum tau tshaj tawm rau 3 hnub ua haujlwm lossis kom txog thaum qhov kev phom sij raug txo, qhov twg yog qhov ntev dua
Vim li cas thiaj tsis tuaj yeem siv adrenaline hauv cov lus tawm tswv yim tsis zoo?
Nws lub hom phiaj tseem ceeb hauv lub cev, ua rau lub plawv dhia nce ntxiv thiab xa cov pa oxygen thiab piam thaj mus rau lub hlwb thiab cov leeg, npaj lub cev rau 'ya dav hlau lossis sib ntaus'. Adrenaline tsis tswj hwm los ntawm kev tawm tswv yim tsis zoo. nws hloov cov ntshav kom deb ntawm thaj chaw, xws li lub plab zom mov, mus rau cov leeg
Dab tsi yog qhov kev tawm tswv yim tsis zoo?
Kev tawm tswv yim tsis zoo yog cov tshuaj tiv thaiv uas ua rau kev ua haujlwm poob qis. Nws tshwm sim los teb rau qee yam kev txhawb siab. Feem ntau nws ua rau cov txiaj ntsig ntawm cov kab ke kom tsawg dua; yog li ntawd, cov lus tawm tswv yim zoo li stabilize lub system. Qhov no tuaj yeem raug xa mus rau homeostatis, xws li hauv biology, lossis kev sib npaug, xws li hauv mechanics
Dab tsi yog qhov txawv ntawm qhov zoo thiab tsis zoo tawm tswv yim homeostasis?
Nrog kev tawm tswv yim zoo, tus ua kom lub zog nce ntxiv uas ua rau ntau tus tsim tawm los tsim. Nrog kev tawm tswv yim tsis zoo, tus effector txo qhov kev txhawb nqa thiab ua rau cov khoom lag luam raug tso tseg. Cov kev tawm tswv yim tsis zoo yog tsim los tswj hwm homeostasis
