Reabsorption yog thaum cov dej thiab cov tshuaj nyob hauv PCT raug tshem tawm thiab rov qab mus rau hauv cov ntshav. Hauv PCT txheej txheem no tshwm sim ntawm kev thauj mus los ntau. Cov tshuaj thiab dej txav los ntawm PCT mus rau interstitium thiab tom qab ntawd nkag mus rau peri-tubular capillaries. Cov reabsorption hauv cev proximal yog isosmotic.
Yooj yim li ntawd, dab tsi yog reabsorbed nyob rau hauv qhov sib thooj convoluted tubule?
Dej hauv cov lim dej nkag mus rau hauv proximal convoluted tubule yog reabsorbed nyob rau hauv lub peritubular capillaries. Sodium reabsorption Feem ntau yog tsav los ntawm P-hom ATPase no. 60-70% ntawm cov lim dej lim dej yog reabsorbed nyob rau hauv lub tubules sib thooj los ntawm kev thauj mus los, hnyav hnyav, thiab paracellular electrodiffusion.
Qhov thib ob, vim li cas xaiv xaiv rov tshwm sim ntawm qhov sib thooj sib sib zog nqus tubule? Xaiv reabsorption tshwm sim vim tias thaum lub sijhawm ultrafiltration, cov khoom tseem ceeb ntawm cov ntshav raug lim tawm thiab lawv yuav tsum tau ua reabsorbed rau hauv lub cev. Qhov no tshwm sim los ntawm lawv diffusing los ntawm cov lim mus rau hauv cov cell hauv ob sab phlu proximal convoluted tubule.
Ntxiv rau qhov no, qhov twg reabsorption tshwm sim hauv nephron?
Reabsorption . Reabsorption Nws yuav siv sij hawm qhov chaw nyob rau hauv lub proximal convoluted tubule ntawm lub 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 tubules.
Yuav 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 txawv degrees tshaj tag nrho qhov ntev ntawm lub lub raum cev. Tej reabsorption , uas tsis nyob hauv kev tswj hwm hormonal, tshwm sim feem ntau nyob rau hauv lub cev tubular.

Dab tsi yog qhov sib thooj thiab qhov sib thooj?
Contiguity vs. Contingency nyob rau hauv txias. Qhov sib thooj: CS sib koom ua ke nrog Asmeskas: lawv tsis sib xws, lossis nyob ze ua ke, hauv qhov chaw thiab sijhawm. Kev Cuam Tshuam: CS kwv yees Asmeskas: qhov tshwm sim ntawm Asmeskas yog nyob ntawm qhov tshwm sim ua ntej ntawm CS
Yuav ua li cas cov leeg sib zog tshwm sim ntawm ib leeg cov qib fiber ntau?
Kev Sib Cais ntawm Cov Nqaij Nqaij. Tus ntoo khaub lig sib txuas ntawm cov actin thiab lub taub hau myosin ua rau muaj kev sib zog. Tsuav ntev li Ca ++ ions nyob hauv sarcoplasm los khi rau troponin, thiab tsuav yog ATP muaj, cov leeg nqaij yuav txuas ntxiv kom luv
Dab tsi tau nqus rau hauv qhov sib thooj sib sib zog nqus tubule?
Kev nqus. Cov tubular sib thooj ua tau zoo tswj hwm pH ntawm cov lim dej los ntawm kev sib pauv hydrogen ions hauv cov interstitium rau bicarbonate ions hauv cov lim dej; nws tseem yog lub luag haujlwm rau zais cov organic acids, xws li creatinine thiab lwm lub hauv paus, rau hauv cov lim dej
Yuav ua li cas tshwm sim rau lub plab thaum lub nqus dej thiab nqus pa?
Kev nqus pa thiab Ua pa Thaum lub sijhawm nqus pa, lub ntsws lub ntsws nthuav dav los ntawm kev sib cais ntawm lub diaphragm thiab cov leeg nqaij sib txuas (cov leeg uas txuas nrog rau kab tav tav), yog li nthuav dav kab noj hniav. Thaum exhalation, lub ntsws rov qab los yuam huab cua tawm ntawm lub ntsws
Yuav tsum sib sib zog nqus hauv siab li cas hauv CM?
Yam tsawg kawg ntawm lub hauv siab compression: compression qhov tob rau cov neeg laus yog tsawg kawg yog 5 cm / 2 nyob rau hauv. Compression qhov tob rau tus me nyuam yog tsawg kawg yog ? qhov tob ntawm lub hauv siab loj, los yog 5 cm rau ib tug me nyuam thiab 4 cm rau tus me nyuam mos
