Kev tshem tawm cov kua qaub (los yog tsim ntawm bicarbonate) los ntawm ob lub raum yog tsim nyog rau acid-base homeostasis. Phosphate yog qhov tseem ceeb tshaj plaws tso zis tsis muaj ; nws tso zis excretion nce nrog acidosis.
Ua li no, dab tsi yog qhov tsis nyob hauv cov zis?
PHOSPHATE BUFFER hauv cov zis Feem ntau phosphate tsuas yog tsis nyob hauv cov zis Txawm hais tias carbonic acid / bicarbonate kuj tseem muaj. Kev loj hlob tso zis muaj NaH2PO4/Na2HPO4 nyob rau hauv tib lub concentration raws li tam sim no nyob rau hauv cov ntshav plasma.
Tsis tas li ntawd, cov tshuab tsis siv neeg ua haujlwm li cas? A tsis pub Nws yog ib qho kev sib xyaw ntawm cov kua qaub tsis muaj zog thiab nws lub hauv paus conjugate los yog lub hauv paus tsis muaj zog thiab nws cov kua qaub conjugate. Buffers ua haujlwm los ntawm reacting nrog ib qho ntxiv acid los yog hauv paus los tswj pH. Raws li cov piv txwv saum toj no qhia, a tsis ua haujlwm los ntawm kev hloov lub zog acid lossis lub hauv paus nrog ib qho tsis muaj zog.
Yog li ntawd, dab tsi yog qhov tseem ceeb ntawm cov kab mob urinary?
Cov bicarbonate tsis pub yog cov thawj buffering system ntawm IF nyob ib puag ncig cov hlwb hauv cov ntaub so ntswg thoob plaws lub cev. Cov ua pa thiab lub raum systems kuj ua si loj Lub luag haujlwm hauv acid-base homeostasis los ntawm kev tshem tawm CO2 thiab hydrogen ions, feem, los ntawm lub cev.
Yuav ua li cas hydrogen tawm ntawm lub cev?
2. Kev tso tawm ntawm Hydrogen Ions (H+) los ntawm lub raum. Thaum cov ntshav ua kua qaub dhau lawm, nws lub raum tshem tawm H+ ions los ntawm lub cev thiab tso tawm lawv nyob rau hauv cov zis. Hydrogen ions raug tshem tawm los ntawm cov tubules sib thooj (PCTs) thiab khaws cov tubules (CTs) uas yog ib feem ntawm cov nephrons ntawm ob lub raum.

Qhov zoo thiab qhov tsis zoo ntawm Mercator projection yog dab tsi?
Disadvantages: Mercator projection distorts qhov loj ntawm cov khoom raws li lub latitude nce los ntawm Equator mus rau tus ncej, qhov twg lub teev yuav infinite. Yog li, piv txwv li, Greenland thiab Antarctica tshwm sim ntau dua qhov txheeb ze rau thaj av loj nyob ze ntawm txoj kab nruab nrab tshaj li qhov lawv muaj tiag
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov tsiaj cloning?
Daim ntawv teev cov Disadvantages ntawm Cloning Tsiaj Cloning tsiaj yog qhov tsawg kawg nkaus txoj kev tsim cov me nyuam. Cloning tsiaj yog kim. Cloning tsiaj txo cov noob caj noob ces ntawm cov tsiaj ntawd. Cloning tsiaj thaum kawg yuav qeeb tus nqi ntawm kev yug me nyuam
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm AC tshaj DC?
Nyob rau hauv AC kis tau tus mob system, lub hwj chim yuav kis tau nyob rau hauv ntev nyob deb thiab nyob rau hauv DC transmisson system, qhov poob yog tsawg. Nyob rau hauv AC kis tau tus mob system, lub hwj chim yuav kis tau nyob rau hauv ntev nyob deb thiab nyob rau hauv DC transmisson system, qhov poob yog tsawg
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Dab tsi yog qhov cuam tshuam ntawm qhov inductance ntawm cov zis hluav taws xob ntawm lub rectifier?
Qhov chaw inductance muaj qhov cuam tshuam loj heev rau kev ua haujlwm ntawm lub converter vim tias nws lub xub ntiag hloov cov zis voltage ntawm lub converter. Raws li qhov tshwm sim, cov zis hluav taws xob txo qis raws li cov khoom thauj tam sim no txo. Tsis tas li ntawd, cov input tam sim no thiab cov zis voltage waveforms hloov pauv loj heev
