Arterioles nqa ntshav thiab oxygen mus rau hauv cov hlab ntsha me tshaj plaws, cov hlab ntsha. Capillaries yog li ntawd small lawv tsuas pom tau nyob hauv lub tshuab tsom. Cov phab ntsa ntawm capillaries yog permeable rau oxygen thiab carbon dioxide.
Puas arterioles loj dua cov leeg?
Ntau hom hlab ntsha sib txawv me ntsis hauv lawv cov qauv, tab sis lawv qhia tib yam dav dav. Cov hlab ntsha thiab cov hlab ntsha muaj cov phab ntsa tuab dua cov leegthiab cov venules vim lawv nyob ze rau lub plawv thiab tau txais cov ntshav uas nce siab dua (Daim duab 2).
Puas capillaries yog cov hlab ntsha loj tshaj plaws?
Capillaries, tsawg tshaj plaws thiab feem ntau ntawm cov hlab ntsha, tsim kev sib txuas ntawm cov hlab ntsha uas nqa cov ntshav tawm ntawm lub plawv (cov hlab ntsha) thiab cov hlab ntsha uas rov qab mus rau cov ntshav. lub plawv (veins). Lub luag haujlwm tseem ceeb ntawm capillaries yog kev sib pauv khoom ntawm cov ntshav thiab cov ntaub so ntswg.
Puas arterioles yog cov hlab ntsha loj tshaj plaws?
Cov hlab ntsha loj tshaj plaws yog lub aorta, lub ntsiab lus siab siab txuas nrog lub plawv sab laug ventricle. Cov ceg aorta mus rau hauv lub network ntawm cov hlab ntsha me me uas txuas mus thoob plaws lub cev. Cov hlab ntsha me me yog hu ua arterioles thiab capillaries.
3 hom hlab ntsha yog dab tsi?
Muaj peb hom hlab ntsha loj:
- Elastic hlab ntsha.
- Cov hlab ntsha.
- Arterioles.
