Cov kua dej tshwj xeeb, hauv biology, cov kua dej hauv lub cev uas tsis muaj nyob hauv cov hlwb. Nws muaj nyob rau hauvntshav, hauv cov qog ntshav, hauv lub cev kab noj hniav lined nrog serous (moisture-exuding) daim nyias nyias, hauv cov kab noj hniav thiab cov kab ntawm lub hlwb thiab qaum qaum, thiab hauv cov leeg thiab lwm lub cev. ntaub so ntswg.
Cov kua dej hauv nruab nrog cev nyob qhov twg?
The intracellular kua yog cov kua uas muaj nyob rau hauv hlwb. Cov kua dej extracellular-cov kua dej sab nraud ntawm cov hlwb-yog muab faib rau hauv cov ntshav thiab pom sab nraum cov ntshav; Cov kua dej tom kawg yog lub npe hu ua cov kua nruab nrab.
Dab tsi yog nyob rau hauv cov kua dej ntxiv?
Cov kua dej tawm sab nraud, dhau los, yog tsim los ntawm ntshav ntshav, cov kua nruab nrog cev, cov qog ntshav thiab cov kua dej hloov pauv (xws li cov kua cerebrospinal, kua synovial, aqueous lom zem, kua dej, plab hnyuv. dej, thiab lwm yam). Cov kua nruab nrog cev thiab cov ntshav ntshav yog cov khoom tseem ceeb ntawm cov kua dej ntxiv.
Yuav ua li cas piv txwv ntawm cov kua dej ntxiv?
Piv txwv ntawm cov kua dej no yog cerebrospinal kua, aqueous lom zem nyob rau hauv lub qhov muag, serous kua nyob rau hauv lub serous membranes nyob rau hauv lub cev kab noj hniav, perilymph thiab endolymph nyob rau hauv lub puab pob ntseg, thiab cov kua dej sib koom.. Vim qhov chaw sib txawv ntawm cov kua dej transcellular, cov muaj pes tsawg leeg hloov pauv ntau.
feem ntau ntawm cov kua dej tawm sab nraud nyob qhov twg?
Feem ntau ntawm cov kua dej tawm sab nraud muaj nyob hauv theinterstitium. Ib txwm txav ntawm cov kua nruab nrab ntawm cov compartments yog tswj hwm los ntawm permeability ntawm cov ntaub so ntswg tshwj xeeb thiab cov concentration ntawm molecules nyob thoob plaws lub membrane barrier. Tag nrho cov compartments muaj cov solutes yaj nyob rau hauv dej.

Puas yog cov kua dej nres lub hwj chim tswj cov kua dej?
Cov kua nplaum thiab lub hwj chim tswj cov kua dej yogob lub kua siv hauv lub tshuab hydraulic hauv cov tsheb niaj hnub, tab sis qhov zoo sib xws tsis mus deb tshaj qhov ntawd. Nres thiab lub hwj chim tswj cov kua dej tau tsim thiab ua kom zoo nyob rau ntau xyoo los ua haujlwm sib txawv hauv cov tsheb, thiab lawv tsis hloov pauv.
Puas yog cov roj cholesterol ua kom cov kua dej ua kua dej?
Thaum qhov kub thiab txias, cov roj cholesterol ua rau cov kua dej ua kom cov kua dej ntau dualos ntawm kev tiv thaiv cov lipids los ntawm kev ntim khoom sib ze. Thaum qhov kub thiab txias, cov roj (cholesterol) yuav txo qis hauv daim nyias nyias.
