Kev ncig ua haujlwm muaj peb yam kev ywj pheej uas ua haujlwm ua ke: lub plawv (kab mob plawv), ntsws (pulmonary), thiab cov hlab ntsha, leeg, coronary thiab portal cov nkoj (systemic). Lub kaw lus yog lub luag haujlwm rau kev khiav ntawm cov ntshav, cov as-ham, oxygen thiab lwm yam gases, thiab nrog rau cov tshuaj hormones mus rau thiab los ntawm cov hlwb.
Hauv txoj kev no, 5 qhov tseem ceeb ntawm txoj kev ncig ua haujlwm yog dab tsi?
Cov no yog lub luag haujlwm tseem ceeb ntawm cov hlab ntsha. Cov plawv , cov ntshav thiab cov hlab ntsha ua haujlwm ua ke los pab cov hlwb ntawm lub cev.
Hauv nplooj ntawv no:
- Ntshav.
- Lub siab.
- Sab xis ntawm lub plawv.
- Sab laug ntawm lub plawv.
- Cov hlab ntsha.
- Cov hlab ntsha.
- Capillaries.
- Cov leeg.
Tsis tas li ntawd, txhua feem ntawm lub circulatory system ua dab tsi? 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.
Dhau li ntawm saum toj no, dab tsi yog hom circulatory system?
Muaj ob lub ntsiab hom kev ncig ua haujlwm : qhib circulatory systems thiab kaw circulatory systems . Qhib circulatory systems yog tshuab qhov twg sab hauv nruab nrog cev thiab cov nqaij hauv lub cev nyob ib puag ncig ntshav ncig kua.
4 lub luag haujlwm ntawm cov hlab ntshav yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm Cardiovascular System. Ntawm nplooj ntawv no peb ua tib zoo saib plaub lub luag haujlwm tseem ceeb ntawm daim cardiovascualr system - kev thauj mus los , kev tiv thaiv, dej tshuav nyiaj li cas thiab thermoregulation.

Dab tsi yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha capillaries?
Piav qhia: Cov hlab ntshav nqa ntshav nyob hauv siab los ntawm lub plawv mus rau cov kabmob thiab cov nqaij. Lawv cov phab ntsa feem ntau yog tuab dua li cov leeg. Capillaries yog qhov sib txuas ntawm cov hlab ntsha thiab cov leeg thiab me me heev, Cov ntaub so ntswg qee zaum pom tawm thiab rov nco qab los ntawm cov qog ntshav thiab rov qab los rau cov leeg ntshav
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
Dab tsi yog ob txoj hlab ntsha tseem ceeb ntawm cov hlab ntsha?
Lub aorta (lub ntsiab cov ntshav muab rau lub cev) ceg tawm mus rau hauv ob lub ntsiab coronary hlab ntsha (tseem hu ua cov hlab ntsha). Cov hlab ntsha coronary no tawm mus rau hauv cov hlab ntsha me, uas muab cov ntshav oxygen nplua nuj rau tag nrho lub plawv cov leeg. Txoj cai coronary artery muab cov ntshav tsuas yog rau sab xis ntawm lub plawv
Dab tsi yog cov hlab ntsha tseem ceeb ntawm cov hlab ntsha?
Cov hlab ntsha, cov hlab ntsha thiab lymphatic system yog cov hlab ntsha tseem ceeb hauv lub cev circulating system. parasympathetic - lub luag haujlwm rau vasoconstriction
