Dab tsi tsis tshwm sim rau cov pa roj carbon dioxide thaum nws nkag mus rau hauv cov hlab ntshav ? Nws khi rau heme pawg hauv hemoglobin. Ua kom qhov kub thiab txias qis dua pH tsim los ntawm cov leeg pob txha nquag ua rau hemoglobin tso pa ntau dua thaum tawm dag zog thaum twg cov leeg tau so.
Tsis tas li ntawd, carbon dioxide tawm hauv cov ntshav li cas?
Thaum cov pa oxygen nkag mus rau hauv cov ntshav , carbon dioxide tawm nws. Cov pa roj carbon dioxide ( CO2 ) yog cov khoom pov tseg ntawm cov metabolism hauv cellular. Cov pa roj no yog thauj mus rau qhov sib txawv ntawm cov pa oxygen: Nws kis tau los ntawm cov cov ntshav - hla cov kab ntawm cov hnab cua - rau hauv lub ntsws thiab tawm mus rau qhov qhib.
Tseem Paub, peb puas nqus pa carbon dioxide? Thaum twg peb exhale, peb ua pa tawm tsawg dua oxygen tab sis ntau dua carbon dioxide tshaj peb nqus tau. Cov carbon peb ua pa tawm raws li carbon dioxide los ntawm cov pa roj carbon hauv cov zaub mov peb noj. Cov carbon dioxide yog yaj nyob rau hauv cov ntshav, nqa mus rau lub ntsws los ntawm kev ncig, thiab ua pa tawm.
Cov lus nug tseem yog, yuav muaj dab tsi tshwm sim rau carbon dioxide hauv alveoli?
Cov alveoli khaws lub zog tuaj (oxygen) uas koj nqus tau thiab tso cov khoom pov tseg tawm ( carbon dioxide ) koj exhale. Raws li nws txav los ntawm cov hlab ntsha (capillaries) hauv alveoli phab ntsa, koj cov ntshav coj cov pa oxygen los ntawm alveoli thiab muab tawm carbon dioxide mus rau alveoli.
Cov pa ya mus thoob lub cev li cas?
Cov pa koj ua pa hauv los ntawm huab cua hla dhau koj lub ntsws rau hauv koj cov ntshav dhau ntau capillaries hauv lub ntsws. Cov pa - nplua nuj ntshav txav dhau koj cov hlab ntsha pulmonary mus rau sab laug ntawm koj lub siab thiab tawm ntawm lub aorta mus rau tag nrho koj lub cev.

Thaum cov ntshav tawm ntawm txoj hlab ntshav sab xis nkag mus rau dab tsi?
Deoxygenated ntshav tawm hauv plawv, mus rau hauv lub ntsws, thiab tom qab ntawd rov nkag rau hauv lub plawv; Deoxygenated ntshav tawm los ntawm txoj hlab ntshav sab xis los ntawm cov hlab ntsws. Los ntawm txoj cai atrium, cov ntshav raug tso los ntawm tricuspid valve (lossis txoj cai atrioventricular valve), mus rau hauv lub ventricle sab xis
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 yuav ua rau hyperventilation muaj rau cov ntshav cov pa roj carbon dioxide?
Thaum lub sijhawm ua pa ntau dhau qhov kev tshem tawm cov pa roj carbon dioxide los ntawm cov ntshav tau nce. Raws li ib feem ntawm cov pa roj carbon dioxide nyob rau hauv cov ntshav txo qis, ua pa alkalosis, uas tshwm sim los ntawm kev txo acidity los yog nce alkalinity ntawm cov ntshav
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 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
