Ob leeg urea thiab NaCl muaj tib lub osmolarity, muaj tib tus lej tag nrho ntawm osmolyte hais; txawm li cas los xij, cov daim nyias nyias yog permeable mus rau urea, uas yuav dawb diffuse thoob plaws lub cell membrane , thiab impermeable rau NaCl . Nyob rau hauv cov ntaub ntawv ntawm cov qe ntshav liab , qhov no yog hu ua hemolysis (4).
Tsis tas li ntawd, NaCl ua dab tsi rau cov qe ntshav liab?
Osmosis Ib Ntshav Ntshav Ntshav . Tsiaj txhu cov qe ntshav liab muaj ib tug biconcave (doughnut zoo li). Yog cov qe ntshav liab yog tso rau hauv 0.3 M NaCl daws, muaj yog me ntsis net osmotic txav ntawm dej, qhov loj thiab cov duab ntawm cov hlwb nyob zoo ib yam; cov NaCl daws yog isotonic rau cov ntawm tes.
Tsis tas li ntawd, yuav ua li cas thaum cov qe ntshav liab muab tso rau hauv 10 NaCl? Cov teebmeem ntawm hypertonic NaCl . Thaum twg cov ntshav liab muab tso rau Hauv kev daws teeb meem hypertonic, qhov ua tau zoo dua osmotic siab ntawm cov tshuaj da dej piv nrog cov kua dej intracellular ua rau cov dej txav mus rau nws cov osmotic gradient thiab cov dej ntws tawm ntawm cov dej. ntawm tes ntawm osmosis ( 10 ).
Tsis tas li, cov qe ntshav liab nkag mus rau ntsev?
IB QHOV CHAW UA HAUJ LWM Ntshav liab PERMEABILITY . Lawv pom tias thaum lub electrolyte equilibriun cuam tshuam los ntawm qhov sib ntxiv ntawm ntsev los yog dej rau ntshav txawm dhau qhov txwv tsis pub dhau qhov kev hloov pauv tau sau tseg hauv tib neeg ntshav , cov ntshav liab Membrane pom tau tias nyob twj ywm impermeable rau cations sodium thiab potassium.
Yuav ua li cas rau cov qe ntshav liab tso rau hauv 0.9 NaCl daws?
0.9 % ntawm NaCl daws isotonic rau RBC. Yog li 0.1% Rov qab daws ua hypotonic dej yuav nkag mus rau RBC ua rau o thiab tawg ntawm RBC. Raws li qhov concentration ntawm cov dej yog tsawg tshaj li qhov NaCl daws yog li dej yuav nkag rau hauv RBC.

Puas yog lub teeb liab hluav taws xob uas feem ntau txav los ntawm lub cev ntawm tes mus rau lub axon mus rau lub dav hlau axon?
Qhov txiaj ntsig zoo no suav nrog qhov muaj peev xwm ua tau: lub teeb liab hluav taws xob uas ib txwm txav los ntawm lub cev ntawm tes los ntawm lub axon mus rau lub dav hlau axon
Puas yog qos liab liab zoo rau cov neeg mob ntshav qab zib?
Cov qos yaj ywm qab zib muaj cov GL qis dua cov txiv kab ntxwv qab zib. Ntxiv nrog rau cov as -ham, qos liab qab zib kuj muaj anthocyanins. Anthocyanins yog cov tshuaj polyphenolic uas tshawb fawb qhia tias yuav thim rov qab lossis tiv thaiv kev rog thiab hom 2 mob ntshav qab zib los ntawm kev txhim kho insulin tsis kam
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
Puas yog cov qe ntshav liab nkag mus rau urea?
Tib neeg cov ntshav liab (hRBC) muaj qhov tshwj xeeb permeability rau dej (Pf) thiab urea (Purea). Txawm li cas los xij, kev koom tes ntawm ob peb pawg ntshav protein kom nkag mus tau yooj yim ntawm ob qho tib si tseem yog qhov teeb meem ntawm kev sib cav
