Lub hauv paus tseem ceeb ntawm cov ntshav yog: Cov qe ntshav liab -Cov no hlwb thauj oxygen thiab hemoglobin. Cov qe ntshav dawb - Cov no hlwb tiv thaiv lub cev los ntawm kab mob. Ntshav - Nws thauj khoom noj, carbon dioxide thiab nitrogenous pov tseg hauv daim ntawv yaj.
Yog li ntawd, dab tsi yog cov khoom ntawm cov ntshav?
Ntshav yog cov kua dej tshwj xeeb hauv lub cev. Nws muaj plaub yam tseem ceeb: ntshav ntshav , cov qe ntshav liab , cov qe ntshav dawb , thiab cov platelets . Ntshav muaj ntau yam haujlwm, suav nrog: thauj cov pa oxygen thiab cov as-ham mus rau lub ntsws thiab cov ntaub so ntswg.
ob lub ntsiab ntawm cov ntshav yog dab tsi? Cov khoom sib txawv uas ua rau ntshav. Plasma , cov qe ntshav dawb , cov qe ntshav liab , cov platelets.
Ntawm no, ob yam tseem ceeb ntawm cov ntshav yog dab tsi thiab lawv cov feem pua yog dab tsi?
Cov ntshav yog tsim los ntawm cov khoom tsim - erythrocytes, leukocytes, thiab cell fragments hu ua cov platelets -thiab cov kua extracellular matrix hu ua plasma. Ntau tshaj 90 feem pua ntawm cov ntshav ntshav yog dej.
Cov feem pua ntawm cov ntshav sib xyaw yog dab tsi?
Cov no ntshav hlwb (uas tseem hu ua corpuscles lossis "tsim cov ntsiab lus") suav nrog erythrocytes (liab ntshav hlwb, RBCs), leukocytes (dawb ntshav cell), thiab thrombocytes (platelets). Los ntawm ntim, liab ntshav cell tsim txog 45% ntawm tag nrho ntshav , ntshav txog 54.3%, thiab cov qe dawb txog 0.7%.

Cov kab mob tseem ceeb ntawm kev txhawj xeeb thaum tham txog cov txheej txheem cov kab mob hauv cov ntshav yog dab tsi?
Cov kab mob tseem ceeb ntawm kev txhawj xeeb yog tib neeg kev tiv thaiv kab mob tsis zoo (HIV), kab mob siab B (HBV), thiab kab mob siab C (HCV). Cov neeg ua haujlwm thiab cov tswv ntiav haujlwm yuav tsum ua kom muaj txiaj ntsig ntawm kev tswj hwm kev tsim vaj tsev thiab kev ua haujlwm txhawm rau tiv thaiv kom tsis txhob muaj ntshav thiab lwm yam kua hauv lub cev
Dab tsi tsuas yog lim los ntawm cov hlab ntshav los ntawm glomerulus thiab tsis rov qab nqus mus rau hauv cov hlab ntshav tab sis tawm los ntawm cov zis?
Creatinine yog cov khoom pov tseg los ntawm cov leeg tawg thiab raug tshem tawm los ntawm cov ntshav los ntawm glomerulus ntawm nephron. Nws tsuas yog cov khoom uas tsuas yog lim tawm ntawm cov ntshav tab sis TSIS tau rov ua dua rau hauv lub cev. Nws raug tso tawm los ntawm cov zis
Dab tsi yog qee yam ntawm cov kab mob loj hauv kev cuam tshuam nrog cov hlab ntshav ncig?

Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
Dab tsi yog lub npe ntawm cov hlab ntshav uas nqa ntshav ntshav los ntawm lub taub hau caj dab thiab caj npab mus rau sab xis atrium?
