| Lub sij hawm Ntshav | Kev Txhais Lus Cov kua dej hauv lub cev |
|---|---|
| Lub sij hawm Hematocrit | Txhais cov feem pua ntawm tag nrho cov ntshav ntim los ntawm cov xov tooj ntawm tes |
| Lub sij hawm Hemoglobin | Cov Lus Txhais Nyiaj Txiag rau ntau dua 95% ntawm RBC cov kab mob intracellular; lub luag haujlwm ntawm tes muaj peev xwm thauj |
Ib sab ntawm qhov no, pes tsawg feem pua ntawm cov ntshav ntim nrog cov khoom tsim?
Cov tsim ntsiab ntawm ntshav yog liab ntshav hlwb (erythrocytes), dawb ntshav cell (leukocytes), thiab platelets (thrombocytes). Ntshav cell thiab platelets ua kwv yees li 45% ntawm tag nrho ntshav ntim . Hematocrit yog feem pua ntawm tag nrho ntshav ntim uas yog nyob nrog liab ntshav hlwb.
puas yog cov neeg nyob coob tshaj plaws ntawm cov neeg tsim cov ntshav? Erythrocytes (liab cov qe ntshav ) Erythrocytes, lossis liab cov qe ntshav , yog tshaj plaws ntau ntawm cov tsim ntsiab.
Qhov thib ob, lub cev twg tsim tawm thiab tshaj tawm ntau dua 90% ntawm cov protein ntshav?
Cov no ntshav protein yog tso tawm rau hauv ntshav los ntawm cov cell uas lawv nyob synthesized . Ntau ntawm protein ntau ntawm ntshav yog tsim tawm hauv lub siab. Qhov loj ntshav protein yog serum cov albumin , ib qho piv txwv me me, lub luag haujlwm tseem ceeb ntawm uas yog khaws cov dej hauv cov ntshav los ntawm nws cov txiaj ntsig osmotic.
Dab tsi yog qhov feem ntau tshaj ntawm cov ntshav?
*Ntau lub qia hlwb muab nce rau txhua qhov tsim los ntawm cov ntshav. Cov feem ntau muaj feem ntawm ntshav yog dej. *Dej ua rau 91% ntawm ntshav.

Qhov twg ntawm tsib lub ntsiab lus ua rau feem pua ntau tshaj hauv tib neeg cov plaub hau?
Tshooj 11 Cov Khoom Ntawm Cov Plaub Hau thiab Cov Khaub Ncaws (Phau Ntawv #3) AB Tsib lub ntsiab lus tseem ceeb uas tsim cov tshuaj lom neeg muaj pes tsawg leeg yog cov pa roj carbon, oxygen, hydrogen, thiab nitrogen thiab sulfur Cov tshuaj sib txuas uas tuav cov amino acid molecules hu ua peptide daim ntawv cog lus
Puas yog tag nrho cov hlab ntsha nqa cov ntshav oxygenated thiab cov leeg nqa cov ntshav deoxygenated?
Cov hlab ntsha ua ib feem ntawm lub circulatory system. Cov hlab ntsha nqa cov ntshav oxygenated tawm ntawm lub plawv mus rau cov ntaub so ntswg, tshwj tsis yog cov hlab ntshav hauv lub ntsws, uas nqa ntshav mus rau lub ntsws rau cov pa oxygen (feem ntau cov leeg ntshav nqa cov ntshav deoxygenated mus rau lub plawv tab sis cov leeg hauv ntsws nqa cov ntshav oxygenated ib yam)
Dab tsi yog qhov kev phais tshem tawm tag nrho lossis ib feem ntawm lub ntsws?
Lobectomy: yog txheej txheem phais feem ntau uas cuam tshuam nrog kev tshem tawm ntawm ib leeg ntawm lub ntsws. Pneumonectomy: yog hais txog kev tshem tawm tag nrho lub ntsws
Qhov feem pua ntawm cov pa oxygen hauv cov ntshav yog dab tsi?
Cov pa oxygen arterial li ib txwm yog kwv yees li 75 txog 100 millimeters mercury (mm Hg). Cov nqi qis dua 60 mm Hg feem ntau qhia tias xav tau cov pa oxygen ntxiv. Kev nyeem ntawv mem tes oximeter feem ntau yog li ntawm 95 txog 100 feem pua. Cov txiaj ntsig qis dua 90 feem pua suav tias yog qis
Dab tsi yog qhov feem ntau ntawm tag nrho cov qog metastatic?
Yuav luag txhua cov qog nqaij hlav, suav nrog qog noj ntshav ntawm cov ntshav thiab cov kab mob qog ntshav (mob qog ntshav, ntau yam mob qog noj ntshav, thiab qog ntshav qog ntshav), tuaj yeem tsim cov qog nqaij hlav. Txawm hais tias tsis tshua muaj, qhov metastasis ntawm cov ntshav thiab lymphatic system mob qog noj ntshav rau lub ntsws, lub plawv, lub paj hlwb, thiab lwm yam ntaub so ntswg tau raug tshaj tawm
