Plasma yog lub ntsiab tiv thaiv ntshav thiab feem ntau yog dej, nrog cov protein, ions, cov as -ham, thiab cov khib nyiab sib xyaw ua ke. Liab ntshav cov cell muaj lub luag haujlwm nqa cov pa oxygen thiab cov pa roj carbon dioxide.
Tom qab ntawd, cov ntshav hauv lub cev yog dab tsi?
Ntshav yog lub cev tshwj xeeb kua. Nws muaj plaub yam tseem ceeb: ntshav , cov qe ntshav liab , cov qe ntshav dawb , thiab cov platelets . Ntshav muaj ntau txoj haujlwm sib txawv, suav nrog: thauj cov pa thiab cov as -ham rau lub ntsws thiab cov ntaub so ntswg.
Kuj Paub, cov pa roj carbon dioxide nqa mus rau hauv cov ntshav li cas? Cov pa roj carbon dioxide molecules yog thauj hauv cov ntshav los ntawm cov ntaub so ntswg hauv lub cev mus rau lub ntsws los ntawm ib ntawm peb txoj hauv kev: kev sib cais ncaj qha rau hauv ntshav , khi rau hemoglobin, lossis nqa raws li bicarbonate ion. Thib ob, cov pa roj carbon dioxide tuaj yeem khi rau cov protein ntshav lossis tuaj yeem nkag liab ntshav cell thiab khi rau hemoglobin.
Tsis tas li, qhov 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%.
Dab tsi yog cov khoom siv tsis yog ntawm tes ntawm cov ntshav?
Cov tsis -muaj sia nyob tivthaiv ntawm peb ntshav yog lub npe hu ua extracellular matrix, hu ua plasma, thiab nws ua rau 55% ntawm peb ntshav muaj pes tsawg leeg thiab ua ntshav tshwj xeeb ntawm cov ntaub so ntswg sib txuas vim nws muaj kua.

Cov pa thiab cov pa roj carbon dioxide thauj hauv cov ntshav li cas?
Cov pa nkag mus rau hauv cov ntshav los ntawm lub ntsws thiab cov pa roj carbon dioxide raug tshem tawm ntawm cov ntshav mus rau hauv lub ntsws. Cov ntshav ua haujlwm thauj ob lub nkev. Cov pa tau nqa mus rau cov cell. Cov pa roj carbon dioxide raug tshem tawm ntawm cov cell
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
Dab tsi tshwm sim rau cov pa roj carbon dioxide ua ntej cov ntshav nkag mus rau sab laug ntawm lub plawv?
Nyob rau tib lub sijhawm, cov pa roj carbon dioxide, cov khoom pov tseg ntawm cov metabolism, kis los ntawm cov ntshav mus rau hauv cov hnab cua. Cov pa roj carbon dioxide tawm ntawm lub cev thaum koj nqus pa. Thaum cov ntshav tau lim thiab oxygenated, nws rov qab mus rau sab laug atrium los ntawm cov hlab ntsws
Puas yog carbon dioxide thauj hauv cov qe ntshav liab?
Cov pa roj carbon dioxide tau thauj hauv cov ntshav los ntawm cov ntaub so ntswg mus rau lub ntsws hauv peb txoj hauv kev: 1 (i) yaj hauv kev daws; (ii) buffered nrog dej ua carbonic acid; (iii) khi rau cov protein, tshwj xeeb tshaj yog hemoglobin. Kwv yees li 75% ntawm cov pa roj carbon dioxide yog thauj hauv cov ntshav liab thiab 25% hauv cov ntshav
Puas yog cov hnab pa me me los ntawm cov pa oxygen thiab carbon dioxide nkag mus rau hauv thiab tawm ntawm cov hlab ntsha?
Cov pa roj carbon dioxide hauv cov ntshav yog pauv rau cov pa oxygen hauv alveoli. Cov hnab cua me me hauv lub ntsws tsuas yog ib lub cell tuab thiab lawv nyob ib puag ncig los ntawm cov hlab ntshav uas tseem muaj ib lub cell tuab xwb. Ntshav los ntawm lub plawv ntws los ntawm cov capillaries thiab khaws cov pa oxygen los ntawm alveoli
