Cov circulatory system ntawm lub ntsws yog ib feem ntawm qhov cov hlab plawv nyob rau hauv uas cov ntshav-ua kom cov ntshav raug tshem tawm ntawm lub plawv, ntawm cov hlab ntsws, mus rau lub ntsws thiab rov qab, oxygenated, rau lub plawv ntawm pulmonary leeg. 2 yog tso tawm los ntawm cov ntshav, thiab oxygen absorbed.
Yog li ntawd, dab tsi yog lub luag haujlwm ntawm lub ntsws hauv cov hlab ntshav?
Cov lub ntsws 'lub ntsiab luag hauj lwm yog nqa tawm hauv huab cua los ntawm huab cua thiab kis oxygen mus rau hauv cov hlab ntsha. Los ntawm qhov ntawd, nws nthuav mus rau tag nrho lub cev.
Qhov thib ob, txoj kev ncig ua haujlwm zoo li cas? Cov circulatory system yog tsim los ntawm cov hlab ntshav uas nqa ntshav tawm ntawm thiab mus rau lub plawv. Cov hlab ntsha nqa ntshav tawm ntawm lub plawv thiab cov hlab ntsha nqa ntshav rov qab mus rau lub plawv. Cov circulatory system nqa cov pa oxygen, cov as -ham, thiab cov tshuaj hormones rau cov cell, thiab tshem tawm cov khoom pov tseg, xws li cov pa roj carbon dioxide.
Yog li ntawd, lub ntsws puas yog ib feem ntawm lub circulatory system?
Cov circulatory system muaj peb tus neeg ywj pheej tshuab uas ua haujlwm ua ke: lub plawv ( plawv ), lub ntsws (pulmonary), thiab cov hlab ntsha, hlab ntsha, coronary thiab portal hlab ntsha (systemic). Cov lawv yog lub luag haujlwm rau cov ntshav, cov khoom noj khoom haus, cov pa oxygen thiab lwm yam roj cua, thiab ntxiv rau cov tshuaj hormones rau thiab los ntawm cov cell.
Lub luag haujlwm tseem ceeb ntawm cov hlab ntshav yog dab tsi?
Cov cov hlab plawv muaj lub plawv, cov hlab ntsha, thiab cov ntshav. Qhov no lawv muaj peb lub luag haujlwm tseem ceeb : Thauj cov as -ham, oxygen, thiab cov tshuaj hormones mus rau cov cell thoob plaws lub cev thiab tshem tawm cov zom zaub mov pov tseg (carbon dioxide, nitrogenous pov tseg).

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 twg tuaj yeem khaws cov qog ntshav los ntawm lub hauv siab thiab hauv qab hauv lub cev?
Cev thoracic
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
Cov hlab ntsha hauv lub ntsws txawv li cas ntawm cov hlab ntsha hauv nruab nrog cev?
Cov hlab ntsha. Cov hlab ntsha hauv lub ntsws nqa cov ntshav oxygen tsawg los ntawm txoj hlab ntshav ntawm lub plawv mus rau lub ntsws. Cov hlab ntsha hauv lub cev thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Cov leeg
