Cov ntawm tes yog hloov tau thiab xav tias lub tswb zoo li nws hla dhau qhov me me ntshav cov nkoj. Nws yog them nrog ib daim nyias nyias uas muaj lipids thiab proteins, tsis muaj ib tug nucleus, thiab muaj hemoglobin-a. liab , hlau-nplua nuj protein uas khi oxygen.
Ua li no, tus qauv ntawm cov qe ntshav liab yog dab tsi?
Vertebrate cov qe ntshav liab suav nrog feem ntau ntawm hemoglobin, cov metalloprotein nyuaj uas muaj cov pab pawg heme uas nws cov hlau atoms khi ib ntus rau cov pa oxygen (O2) nyob rau hauv lub ntsws lossis cov pos hniav thiab tso tawm thoob plaws lub cev. Oxygen tuaj yeem yooj yim diffuse los ntawm cov qe ntshav liab liab daim nyias nyias.
Ib yam li ntawd, cov qe ntshav liab txhais li cas hauv biology? Cov qe ntshav liab : Cov cov qe ntshav uas nqa oxygen. Cov hlwb liab muaj hemoglobin thiab nws yog hemoglobin uas tso cai rau lawv thauj oxygen (thiab carbon dioxide). Cov qe ntshav liab yog tej lub sij hawm tsuas hu liab liab . Lawv yog tseem hu ua erythrocytes lossis, tsis tshua muaj hnub no, ntshav liab lub cev.
Hais txog qhov no, dab tsi yog cov organelles hauv cov qe ntshav liab?
Txawm hais tias RBCs suav hais tias yog cov hlwb, lawv tsis muaj ib qho cev , nuclear DNA, thiab feem ntau organelles, suav nrog endoplasmic reticulum thiab mitochondria.
Lub luag haujlwm tseem ceeb ntawm cov qe ntshav liab yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm cov qe ntshav liab, lossis erythrocytes, yog nqa oxygen los ntawm lub cev lub ntsws mus rau lub cev cov ntaub so ntswg thiab carbon dioxide raws li cov khoom pov tseg, deb ntawm cov ntaub so ntswg thiab rov qab mus rau lub lub ntsws . Hemoglobin (Hgb) yog cov protein tseem ceeb hauv cov qe ntshav liab uas nqa oxygen los ntawm lub cev lub ntsws rau txhua qhov ntawm peb 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
Cov qe ntshav liab liab hemolysis yog dab tsi?
Hemolysis yog kev puas tsuaj ntawm cov qe ntshav liab. Hemolysis tuaj yeem tshwm sim los ntawm ntau yam ua rau thiab ua rau tso hemoglobin rau hauv cov ntshav. Cov qe ntshav liab ib txwm muaj (erythrocytes) muaj lub neej nyob ntev txog 120 hnub. Tom qab lawv tuag lawv tawg thiab raug tshem tawm ntawm kev ncig los ntawm tus po
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
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?
