Muaj peb hom tseem ceeb ntawm cov hlab ntsha:
- Cov hlab ntsha . Lawv nqa cov ntshav uas muaj pa oxygen tawm ntawm lub plawv mus rau tag nrho lub cev nqaij daim tawv.
- Capillaries . Cov no yog cov hlab ntsha me me, nyias uas txuas rau cov hlab ntsha thiab cov leeg .
- Cov leeg .
Los ntawm qhov ntawd, lub luag haujlwm ntawm 3 hom hlab ntshav yog dab tsi?
Lub ntsiab muaj nuj nqi ntawm cov hlab ntsha yog nqa ntshav dhau lub cev. Cov ntshav nqa cov pa oxygen, cov as -ham, thiab pov tseg uas yuav tsum tau txav mus los thoob plaws lub cev. Muaj peb hom hlab ntsha : cov hlab ntsha, leeg, thiab capillaries.
Tsis tas li, peb hom tseem ceeb ntawm cov hlab ntsha loj tshaj plaws mus rau qhov tsawg tshaj plaws yog dab tsi? Cov hlab ntsha suav nrog cov hlab ntsha, cov leeg ntshav, thiab cov hlab ntsha.
- Arteries yog cov leeg nqaij uas nqa 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.
Kuj nug, cov hom hlab ntsha yog dab tsi?
Muaj ntau hom hlab ntsha:
- Cov hlab ntsha.
- Elastic hlab ntsha.
- Kev faib cov hlab ntsha.
- Arterioles.
- Capillaries (cov hlab ntsha me tshaj)
- Venules.
- Cov leeg. Cov nkoj loj sau, xws li cov leeg subclavian, cov hlab ntshav jugular, lub raum leeg thiab cov leeg leeg.
- Sinusoids.
Muaj pes tsawg cov hlab ntsha hauv lub cev?
Tab sis yog tias koj coj tag nrho cov cov hlab ntsha tawm ntawm tus menyuam nruab nrab thiab tso lawv tawm hauv ib kab, kab yuav nthuav dav ntau dua 60, 000 mais. Ib tus neeg laus yuav nyob ze dua 100,000 mais ntev. Muaj peb hom cov hlab ntsha : cov hlab ntsha, leeg, thiab 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
Vim li cas peb thiaj sau cov ntshav los ntawm cov hlab ntsha thiab tsis yog los ntawm cov hlab ntsha?
Cov leeg yuav tsum tau li qub kom cov ntshav ntws mus rau lub plawv. Theses li qub yog qhov tshwj xeeb hauv ob txhais ceg thiab caj npab. Lawv tawm tsam lub ntiajteb txawj nqus los tiv thaiv cov ntshav rov qab los. Cov hlab ntsha tsis xav tau li qub vim tias lub siab los ntawm lub plawv ua kom cov ntshav ntws los ntawm lawv mus rau ib qho
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
