Cov tshuaj reabsorbed hauv PCT suav nrog urea, dej, potassium, sodium, chloride, qabzib, amino acids, lactate, phosphate, thiab bicarbonate. Txij li cov dej kuj tseem rov nqus cov kua hauv lub voj voog ntawm Henle tsawg dua li PCT, kwv yees li ib feem peb ntawm cov khoom qub.
Cov kuab tshuaj reabsorbed nyob rau hauv lub nephron nyob qhov twg?
Cov Tubule Proximal Reabsorbs Cov Khoom Lim Lim. Tus nqi ntawm reabsorption thiab tso tawm ntawm cov khoom lim dej sib txawv ntawm ntu ntawm lub raum tubule. Feem ntau, cov tubule proximal reabsorbs ntau ntawm cov ultrafiltrate dua li lwm cov tubule ntu ua ke, tsawg kawg yog 60% ntawm cov lim dej feem ntau.
Yuav ua li cas cov tshuaj reabsorbed hauv nephron?
NaNtau Ca++, Na+, qabzib, thiab amino acids yuav tsum tau reabsorbed los ntawm nephron kom tswj tau homeostatic plasma concentrations. Lwm yam tshuaj xws li urea, K+, ammonia (NH3), creatinine, thiab qee qhov Cov tshuaj tau muab zais rau hauv cov lim raws li cov khoom pov tseg.
Sodium reabsorbed nyob rau hauv lub voj nephron nyob qhov twg?
Sodium reabsorbed nyob rau hauv lub tuab ascending limb ntawm lub voj ntawm Henle, los ntawm Na-K-2Cl symporter thiab Na-H antiporter.
Puas nephron voj reabsorb urea?
Urea yog lim dawb, 50% yog reabsorbednyob rau hauv lub tubule ze nrog lub reabsorption ntawmdej (kwv yees rub). Urea yog secreted nyob rau hauv nyias ascending limb ntawm Henle voj, yog li cov nyiaj tseem ceeb ntawm urea ncav cuag lub distal nephron. Hauv cov ducts sau, urea yog reabsorbed ua ke nrog dej.

Cov piv txwv ntawm cov kuab tshuaj thiab cov kuab tshuaj yog dab tsi?
Solutes yog cov khoom uas yaj rau hauv cov kuab tshuaj thiab peb xaus nrog kev daws. Qee qhov piv txwv ntawm cov kuab tshuaj yog dej, ethanol, toluene, chloroform, acetone, mis nyuj, thiab lwm yam. Piv txwv ntawm cov kuab tshuaj muaj xws li, qab zib, ntsev, oxygen, thiab lwm yam … Cov dej dej muaj dej (kua kua) thiab yaj oxygen (solute).
Hauv kev tshuaj ntsuam organoleptic cov tshuaj raug tshuaj xyuas los ntawm?
Kev ntsuas tshuaj muaj ntau txoj hauv kev uas yuav raug cais raws li hauv qab no: Organoleptic thiab morphological kev ntsuam xyuas: Kev ntsuam xyuas los ntawm txhais tau tias ntawm lub cev ntawm kev nkag siab paubxim, tsw, saj, qhov loj me, cov duab thiab cov yam ntxwv tshwj xeeb xws li kev ntxhib los mos.
Puas muaj cov kuab tshuaj ntau dua li cov kuab tshuaj?
Ib tshuaj yog ib homogeneous sib tov ntawm ob los yog ntau tshaj tshuaj. Cov khoom uas muaj nyob rau hauv qhov loj tshaj plaws yog hu ua cov kuab tshuaj thiab ib qho tam sim no nyob rau hauv lub me me yog hu ua ib tug solute. Tsuas muaj ib qho kuab tshuaj xwb, tab sis muaj peev xwm ua tau ntau yam.
Vim li cas dej yog cov kuab tshuaj zoo rau recrystallization ntawm acetanilide?
Vim li cas dej yog cov kuab tshuaj zoo rau recrystallization ntawm acetanilide? Acetanilide nkag tau yooj yim yaj hauv dej kub, tab sis yog insoluble ntawm qis temps. Yog li, nws dissolves hauv dej kub tab sis crystalizes yooj yim thaum txias.
Lub voj sib txawv ntawm lub voj voog thaum lub sijhawm ntawd?
Qhov txawv nyob ntawm qhov chaw kuaj mob. The while loop test the condition ua ntej executing any of the statement in the while loop where the do-while loop tests tus mob tom qab cov nqe lus tau ua tiav hauv lub voj. Dab tsi txawv ntawm thaum thiab ua-thaum lub voj hauv C?
