Cov peripheral chemoreceptors yog ncaj qha rhiab heev rau ib nrab ntawm cov pa oxygen thiab cov pa roj carbon dioxide nrog rau Ntshav pH; Txawm li cas los xij, cov txheej txheem uas cov ntsiab lus ntawm cov molecules no txuas nrog chemoreceptor kev ua haujlwm tsis nkag siab zoo.
Thiaj li, cov khoom siv tshuaj lom neeg sab nraud teb rau dab tsi?
Peripheral chemoreceptors . Peripheral chemoreceptors yog extensions ntawm ib puag ncig lub paj hlwb teb rau hloov pauv cov ntshav cov ntshav ntau (xws li oxygen lossis carbon dioxide) thiab pab tswj kev mob plawv hauv tsev. Lawv yog feem ntau nyob hauv lub cev carotid thiab aortic.
Ib yam li ntawd, Chemoreceptors rhiab rau dab tsi? Chemoreceptors nyob rau hauv lub cev carotid thiab aortic koov yog rhiab rau hloov pauv ntawm cov pa roj carbon dioxide, oxygen, thiab pH. Lub cev carotid feem ntau tseem ceeb dua hauv kev kho kom haum cov lus teb no thiab muab cov txheej txheem tseem ceeb uas cov tsiaj xav tau qis dua cov pa.
Ua qhov no hauv kev txiav txim siab, dab tsi yog ib puag ncig Chemoreceptors nkag siab tshaj rau cov lus nug?
Lawv yog rhiab heev rau PO2. O2 thiab CO2 ua rau kis mus rau CSF. Siab CO2 qib nce H+ ion concentration hauv CSF uas ua rau lub hauv paus chemoreceptors.
Dab tsi yog qhov cuam tshuam loj ntawm ib puag ncig Chemoreceptor txhawb?
Lub cev cov teebmeem ntawm kev siv tshuaj tua kab mob hauv lub cev suav nrog cov hlab ntshav vasodilation thiab vasoconstriction hauv cov leeg pob txha thiab thaj chaw splanchnic.

Feem ntau, cov kev ntsuam xyuas rhiab heev muaj qhov tshwj xeeb tsawg. Hauv lwm lo lus, lawv yog qhov zoo rau kev kis tus mob tiag tiag tab sis lawv kuj tuaj nrog qhov ua tau zoo ntawm qhov ua tsis raug. Mammograms yog ib qho piv txwv ntawm kev ntsuam xyuas uas feem ntau muaj qhov rhiab heev (txog 70-80%) thiab qhov tshwj xeeb tsawg
Post hoc rhiab heev tsom xam yog dab tsi?

Kev soj ntsuam rhiab heev yog kev tshuaj xyuas tom qab uas qhia peb tias peb cov txiaj ntsig zoo li cas. Nws tuaj yeem muab cov ntaub ntawv tshwj xeeb ntawm: Cov kev xav twg yog qhov tseem ceeb, thiab lawv cuam tshuam rau kev tshawb fawb ntau npaum li cas, Cov kev hloov pauv hauv cov qauv, cov qauv, lossis cov txiaj ntsig ntawm qhov ntsuas tsis tau ntsuas cuam tshuam rau cov txiaj ntsig

Kev kuaj tshuaj tua kab mob rhiab heev (lossis susceptibility) yog ua los pab xaiv cov tshuaj tua kab mob uas yuav ua tau zoo tshaj plaws tiv thaiv cov kab mob tshwj xeeb lossis cov kab mob fungus kis rau ib tus neeg. Cov kab mob tshwm sim los ntawm cov kab mob tiv taus kab mob los yog cov kab mob tsis kho los ntawm kev kho nrog cov tshuaj tua kab mob no
