Reabsorption . Reabsorption yuav siv qhov chaw feem ntau nyob hauv qhov sib thooj sib sib zog nqus tubule ntawm nephron. Yuav luag tag nrho cov dej, piam thaj, potassium, thiab cov amino acids poob thaum lub sijhawm glomerular pom rov ua cov ntshav los ntawm lub raum cev.
Khaws qhov no saib, ua li cas reabsorption tshwm sim hauv lub raum?
Reabsorption yog kev txav ntawm cov dej thiab daws los ntawm tubule rov qab rau hauv cov ntshav. Reabsorption ntawm cov dej thiab cov kev daws teeb meem tshwj xeeb tshwm sim mus rau qib sib txawv ntawm tag nrho qhov ntev ntawm lub raum cev. Tej reabsorption , uas tsis nyob hauv kev tswj hwm hormonal, tshwm sim feem ntau nyob rau hauv lub cev tubular.
Kuj Paub, hauv qhov twg ntawm lub raum feem ntau ntawm cov dej reabsorption tshwm sim? Feem ntau dej reabsorption tshwm sim nyob rau hauv qhov sib thooj convoluted tubules, ib feem ntawm nephrons hauv raum . Dej yog reabsorbed los ntawm tus txheej txheem hu ua osmosis; diffusion ntawm dej los ntawm thaj chaw siab dej muaj peev xwm mus rau thaj tsam ntawm qis dej muaj peev xwm dhau los ntawm qee qhov permeable membrane.
Kuj nug, qhov sib txawv ntawm reabsorption thiab tso zis hauv lub raum yog dab tsi?
Lub raum zais zis yog txawv los ntawm reabsorption vim nws cuam tshuam nrog kev lim thiab ntxuav cov tshuaj los ntawm cov ntshav, tsis yog khaws cia. Cov tshuaj uas yog zais rau hauv cov kua tubular kom tshem tawm ntawm lub cev suav nrog: Potassium ions (K+) Hydrogen ions (H+)
Puas yog cov piam thaj reabsorbed hauv lub raum?
Hauv qhov xwm txheej ib txwm, txog li 180 g/hnub qab zib tau lim los ntawm lub raum glomerulus thiab yuav luag txhua qhov nws yog tom qab reabsorbed nyob rau hauv qhov sib thooj convoluted tubule.
