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
Puas yog cov hlab ntsha uas muaj oxygenated ntshav lossis cov hlab ntsha?
