Cov khoom xws li hydrogen ions, penicillin, thiab histamine yog zais los ntawm kev thauj mus los. Potassium thiab ammonium ions yog zais ob qho tib si passively thiab nquag.
Cov tshuaj twg uas nquag tso tawm tsis pub dhau qhov zais cia ua li cas lub reabsorption ntawm sodium cuam tshuam rau kev tso tawm ntawm poov tshuaj?
Passively secreted? Yuav ua li cas reabsorption ntawm sodium cuam tshuam rau kev tso tawm ntawm poov tshuaj? Feem ntau ntawm potassium ions nyob rau hauv glomerular filtrateyog nquag reabsorbed nyob rau hauv lub proximal convoluted tubule, tab sis ib txhia yuav secreted nyob rau hauv lub distal convoluted tubule thiab sau duct.
Yuav ua li cas cov tshuaj nquag zais cia?
Cov tshuaj zais cia ntau suav nrog hydrogen, creatinine, ions, thiab lwm yam khoom pov tseg, xws li tshuaj. Tubular secretion yog kev hloov ntawm cov ntaub ntawv los ntawm peritubular capillaries mus rau lub raum tubular lumen thiab tshwm sim tsuas yog los ntawm active thauj thiab passive diffusion.
Puas zais zais qhov txheej txheem passive?
Cov tshuaj zais cia feem ntau suav nrog hydrogen, creatinine, ions, thiab lwm yam khoom pov tseg, xws li tshuaj. Tubular secretion yog kev hloov ntawm cov ntaub ntawv los ntawm peritubular capillaries mus rau lub raum tubular lumen thiab tshwm sim tsuas yog los ntawm kev thauj mus los thiab passive diffusion.
Yuav ua li cas yog cov tshuaj uas nquag nquag thiab nquag reabsorbed hauv txhua ntu ntawm nephron?
Ntau tus Ca++, Na+, qabzib, thiab amino acids yuav tsum tau rov qab 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.
