Cov dermis muaj ntau ntawm lub cev cov dej haus thiab nws muaj lub luag haujlwm tseem ceeb hauv ob qho tib si tswj qhov kub thiab txias ntshav mus rau epidermis. Cov qauv pom nyob hauv dermis suav nrog: cov ntaub so ntswg sib txuas, tshwj xeeb yog collagen thiab elastin. Ntshav capillaries (qhov tsawg tshaj plaws ntawm cov hlab ntsha ) thiab lwm yam me me cov nkoj.
Hauv qhov no, txheej txheej ntawm daim tawv nqaij puas muaj cov hlab ntshav?
Qhov no ob txheej so ntawm lwm cov ntaub so ntswg sib txuas txheej hu ua Hypodermis los yog cov ntaub so ntswg subcutaneous. Cov ntaub so ntswg sib txuas txheej ntawm daim tawv nqaij ( dermis ) muaj ib tug nplua nuj network ntawm ntshav thiab lymphatic cov nkoj . Epidermis tsis muaj cov hlab ntsha.
Ib yam nkaus, txheej tawv nqaij twg tsis muaj cov hlab ntshav? Cov epidermis yog pom qhov muag thiab ua haujlwm los muab kev tiv thaiv rau lub cev. Nws tsis muaj ib yam cov hlab ntsha thiab yog li ntawd, nyob ntawm daim tawv nqaij, tus txheej ntawm daim tawv nqaij hauv qab nws, txhawm rau nkag mus rau cov as -ham thiab pov tseg pov tseg.
Ib yam nkaus, puas yog cov hlab ntsha hauv lub dermis lossis epidermis?
Tsis muaj cov hlab ntsha nyob rau hauv daim tawv nqaij , thiab cov hlwb nyob rau hauv cov khaubncaws sab nraud povtseg yog nourished los ntawm diffusion los ntawm ntshav capillaries txuas mus rau sab sauv txheej dermis 15. Cov cov hlab ntsha hauv dermis muab khoom noj khoom haus thiab pov tseg ntawm nws tus kheej lub hlwb raws li zoo raws li los ntawm lub stratum basale ntawm lub daim tawv nqaij 16.
Cov hlab ntsha pom nyob qhov twg ntawm daim tawv nqaij?
Lub dermis yog txheej nruab nrab ntawm tawv nqaij , pom hauv qab lub epidermis. Nws yog cov txheej tuab tshaj plaws ntawm tawv nqaij thiab muaj qab haus huv thiab cov hlab ntsha . Nws tseem yog lub tsev rau cov qog hws, qog roj ntsha thiab cov hauv paus plaub hau.
Pom zoo:
Dab tsi tsuas yog lim los ntawm cov hlab ntshav los ntawm glomerulus thiab tsis rov qab nqus mus rau hauv cov hlab ntshav tab sis tawm los ntawm cov zis?
Creatinine yog cov khoom pov tseg los ntawm cov leeg tawg thiab raug tshem tawm los ntawm cov ntshav los ntawm glomerulus ntawm nephron. Nws tsuas yog cov khoom uas tsuas yog lim tawm ntawm cov ntshav tab sis TSIS tau rov ua dua rau hauv lub cev. Nws raug tso tawm los ntawm cov zis
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
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
