Appendicular hlab ntsha . Cov appendicular hlab ntsha yog ib kawg hlab ntsha uas tsis koom nrog lwm tus, thiab nws tsis muaj npe hu ua ceg ntawm nws tus kheej.
Ib qho ntxiv, puas yog cov hlab ntsha splenic yog cov hlab ntsha kawg?
Ib kawg leeg (los yog terminal cov leeg ) yog ib cov leeg uas tsuas yog muab cov ntshav oxygenated rau ib feem ntawm cov ntaub so ntswg. Piv txwv ntawm ib kawg hlab ntsha suav nrog cov hlab ntsha splenic uas muab cov tus po thiab lub raum cov leeg uas muab lub raum.
Kuj Paub, yog cov hlab ntsha coronary kawg cov hlab ntsha? Cov coronary hlab ntsha raug cais raws li " kawg ncig ", txij li lawv sawv cev tsuas yog lub hauv paus ntawm cov ntshav xa mus rau myocardium; muaj qhov tsis txaus cov ntshav ntxiv, yog vim li cas txhav ntawm cov hlab ntsha tuaj yeem yog qhov tseem ceeb.
Ib qho yooj yim, puas yog brachial artery yog cov hlab ntsha kawg?
Cov brachial leeg yog cov hlab ntsha loj ntawm lub caj npab (sab sauv). Nws yog qhov txuas ntxiv ntawm axillary cov leeg dhau ntawm qhov qis ntawm cov leeg teres loj. Nws txuas ntxiv mus rau sab nraub qaum ntawm caj npab kom txog thaum nws mus txog qhov cub fossa ntawm lub luj tshib.
Dab tsi cov hlab ntsha muab cov ntawv ntxiv?
appendicular hlab ntsha
Pom zoo:
Cov hlab ntsha lossis cov hlab ntsha puas khov dua?
Cov hlab ntsha muaj cov leeg ntau dua thiab muaj me dua, puag ncig lub lumens (qhov chaw sab hauv) dua li cov leeg. Nws yog tsim los ntawm cov leeg nqaij du thiab elastic fibers hu ua elastin. Cov txheej ntawm elastin cais cov tunica media los ntawm lwm cov txheej. Tunica media yog txheej tuab tshaj plaws hauv cov hlab ntsha
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
Puas yog cov hlab ntsha uas muaj oxygenated ntshav lossis cov hlab ntsha?
Cov hlab ntsha tau pom tias yog nqa cov ntshav oxygenated mus rau cov ntaub so ntswg, thaum cov leeg nqa cov ntshav deoxygenated rov qab mus rau lub plawv. Txawm li cas los xij, hauv txoj hlab ntsws, cov hlab ntsha nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws, thiab cov hlab ntshav rov qab ntshav los ntawm lub ntsws mus rau lub plawv
