Ntshav siab tuaj yeem txhais raws li qhov siab ntawm ntshav ntawm phab ntsa ntawm cov hlab ntsha thaum nws nthuav dav thoob plaws lub cev. Ntshav siab yog siab tshaj raws li nws tawm hauv plawv los ntawm aorta thiab maj mam txo qis thaum nws nkag mus me dua thiab me dua cov hlab ntsha (cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha).
Raws li txoj cai, hauv cov hlab ntsha dab tsi yog ntshav siab siab tshaj thiab qis tshaj?
Ntshav siab yog siab tshaj hauv cov hlab ntsha thiab qis tshaj hauv cov leeg.
Tom qab ntawd, lo lus nug yog, qhov twg hauv cov hlab ntshav yog ntshav siab qis tshaj? Siab yog siab tshaj thaum pib ntawm cov hlab ntsha thiab qis tshaj ntawm qhov nkag mus rau atrium. Ntshav siab Nws yog ntau dua nyob rau hauv lub aorta tshaj nyob rau hauv cov hlab ntsha pulmonary.
Zoo ib yam tuaj yeem nug, cov hlab ntshav twg muaj cov ntshav siab tshaj?
Tseem ceeb: Qhov siab tshaj siab ntawm circulating ntshav tau pom hauv cov hlab ntsha, thiab kawm tiav qis dua li qhov ntshav ntws los ntawm cov hlab ntsha, cov hlab ntsha, cov hlab ntshav, thiab cov leeg (qhov uas nws yog qis tshaj ). Qhov loj tshaj poob rau hauv ntshav siab tshwm sim ntawm kev hloov ntawm cov hlab ntsha mus rau arterioles.
Dab tsi yog cov hlab ntsha me tshaj plaws hauv lub cev?
Capillaries
Pom zoo:
Hom hlab ntshav twg txuas cov hlab ntsha thiab cov hlab ntshav?
Hom hlab ntsha Capillaries yog feeb nyias-walled hlab ntsha uas txuas cov hlab ntsha thiab venules; Nws yog los ntawm cov capillaries uas cov as-ham thiab cov pov tseg tau pauv ntawm cov ntshav thiab cov ntaub so ntswg ntawm lub cev
Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Cov hlab ntsha twg cov ntshav siab mus txog qhov ntsuas siab tshaj plaws?
Cov hlab ntsha loj tau txais lub siab tshaj plaws ntawm cov ntshav ntws thiab ntau tuab thiab ywj kom haum rau qhov siab. Cov hlab ntsha me, xws li arterioles, muaj cov leeg du uas sib cog lus lossis so kom tswj cov ntshav ntws mus rau qee qhov ntawm lub cev
Qhov twg yuav ua rau qhov txo qis tshaj plaws hauv lub siab ntawm cov hlab ntsha?
Arterioles muaj qhov nce siab tshaj plaws hauv kev tiv thaiv thiab ua rau cov ntshav siab poob qis tshaj plaws. Kev txwv ntawm cov hlab ntsha ua rau muaj zog tiv thaiv uas ua rau txo qis cov ntshav ntws mus rau cov hlab ntsha hauv qab thiab txo qis ntshav siab
