Muaj peb hom hlab ntsha : cov hlab ntsha, leeg, thiab capillaries. Cov hlab ntsha muaj phab ntsa tuab thiab me me hauv lub qhov dua li cov leeg. Yog vim li cas rau qhov no yog cov hlab ntsha nqa ntshav uas yog nqus tag nrho lub cev. Lub tshuab nqus dej ntawd yuav tsum muaj lub zog ntau ntawm lub siab.
Hauv qhov no, qhov sib txawv ntawm cov hlab ntshav yog dab tsi?
Cov hlab ntsha yog cov hlab ntsha lub luag haujlwm rau nqa cov pa oxygen ntau ntshav deb ntawm lub siab mus rau lub cev. Cov leeg yog cov hlab ntsha uas nqa ntshav qis nyob rau hauv oxygen los ntawm lub cev rov qab mus rau lub plawv rau reoxygenation. Cov hlab ntsha thiab cov hlab ntsha yog ob ntawm lub cev hom loj ntawm cov hlab ntsha.
Kuj Paub, 3 hom capillaries yog dab tsi? Capillaries txuas cov hlab ntsha thiab cov hlab ntshav thiab pab kom sib pauv dej, oxygen, carbon dioxide, thiab ntau lwm yam khoom noj thiab cov khoom pov tseg ntawm cov ntshav thiab cov nqaij ib puag ncig. Muaj peb lub ntsiab hom ntawm capillaries : nruam, fenestrated, thiab sinusoidal.
Ntxiv mus, peb hom nkoj yog dab tsi thiab txhua tus ua li cas?
Cov Peb Hom Loj ntawm Ntshav Cov nkoj : Arteries, Veins, thiab Capillaries. Ntshav cov nkoj ntws ntshav thoob plaws lub cev. Cov hlab ntsha thauj cov ntshav tawm ntawm lub plawv. Cov leeg ntshav rov qab mus rau lub plawv.
Peb yam tseem ceeb ntawm cov hlab ntsha loj tshaj plaws mus rau qhov tsawg tshaj plaws yog dab tsi?
Cov hlab ntsha muaj xws li cov hlab ntsha, cov hlab ntsha, thiab capillaries
- Cov hlab ntsha yog cov hlab ntsha uas nqa cov ntshav tawm ntawm lub plawv.
- Cov leeg ntshav yog cov hlab ntshav uas nqa ntshav mus rau lub plawv.
- Capillaries yog cov hlab ntsha me tshaj plaws.

Dab tsi yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha capillaries?
Piav qhia: Cov hlab ntshav nqa ntshav nyob hauv siab los ntawm lub plawv mus rau cov kabmob thiab cov nqaij. Lawv cov phab ntsa feem ntau yog tuab dua li cov leeg. Capillaries yog qhov sib txuas ntawm cov hlab ntsha thiab cov leeg thiab me me heev, Cov ntaub so ntswg qee zaum pom tawm thiab rov nco qab los ntawm cov qog ntshav thiab rov qab los rau cov leeg ntshav
Dab tsi yog qhov txawv ntawm qhov mob hlab ntsha tawg thiab mob hlab ntsha tawg stasis?
Arterial ulcers tsim los ntawm kev puas tsuaj rau cov hlab ntsha vim tsis muaj cov ntshav ntws mus rau cov ntaub so ntswg. Venous ulcers tsim los ntawm kev puas tsuaj rau cov hlab ntsha uas tshwm sim los ntawm cov ntshav tsis txaus rov qab mus rau lub plawv. Tsis zoo li lwm qhov txhab, cov ceg mob no tuaj yeem siv sijhawm ntau lub hlis los kho, yog tias lawv zoo txhua lub sijhawm
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
Koj tuaj yeem qhia qhov sib txawv ntawm cov hlab ntsha thiab cov hlab ntsha li cas?
Cov hlab ntshav yog cov hlab ntshav ua lub luag haujlwm nqa cov pa oxygen ntau ntawm lub plawv mus rau lub cev.Cov leeg ntshav yog cov hlab ntshav uas nqa cov ntshav qis inoxygen los ntawm lub cev rov mus rau lub plawv forreoxygenation
Dab tsi yog peb hom hlab ntsha hauv cov hlab ntsha?
Muaj peb yam tseem ceeb ntawm cov hlab ntsha: cov hlab ntsha. Lawv nqa cov ntshav uas muaj oxygen tawm ntawm lub plawv mus rau tag nrho lub cev cov ntaub so ntswg. Capillaries. Cov no yog cov hlab ntshav me me, uas txuas cov hlab ntsha thiab cov leeg. Cov leeg
