Qhov sib txawv tseem ceeb ntawm aorta thiab cov hlab ntsha yog tias lub aorta yog cov hlab ntsha loj tshaj plaws uas nqa cov ntshav oxygenated los ntawm lub plawv, thaum cov hlab ntsha yog cov hlab ntsha uas nqa cov ntshav oxygenated mus rau lwm lub cev, cov ntaub so ntswg, thiab cov hlwb hauv peb lub cev.
Lub siab yog ib qho tseem ceeb hauv peb lub cev. Nws muab oxygen thiab tag nrho lwm yam khoom noj uas tsim nyog rau peb lub cev. Yog li, lub plawv tso ntshav los ntawm cov hlab ntsha, thiab tag nrho lub cev tau txais kev noj haus los ntawm cov kab mob no. Cov hlab ntsha muaj peb hom; cov hlab ntsha, cov hlab ntsha thiab capillaries. Cov hlab ntsha nqa cov ntshav tawm ntawm lub plawv, feem ntau yog cov ntshav oxygenated los ntawm lub plawv. Capillaries pab txhawb kev sib pauv dej thiab tshuaj ntawm cov ntshav thiab cov ntaub so ntswg. Cov leeg nqa ntshav los ntawm cov hlab ntsha rov qab mus rau lub plawv. Aorta thiab pulmonary artery yog ob txoj hlab ntsha loj txuas nrog lub plawv.
Aorta yog dab tsi?
Aorta yog ib qho ntawm cov hlab ntsha tseem ceeb tshaj plaws hauv peb lub cev. Nws yog cov hlab ntsha loj tshaj plaws uas peb muaj. Aorta yog lub luag haujlwm tseem ceeb ntawm cov hlab ntsha. Nws pib los ntawm sab laug ventricle thiab nqa cov ntshav oxygenated mus rau tag nrho lub cev. Nyob rau ntawm qhov chaw uas nws pib los ntawm sab laug ventricle, muaj lub plawv valve hu ua aortic valve. Nws yog peb daim ntawv uas tuav lub valve, thiab nws tiv thaiv qhov rov qab ntawm cov ntshav oxygenated los ntawm lub aorta mus rau sab laug ventricle.
Daim duab 01: Aorta thiab nws cov ceg
Thaum lub aorta pib los ntawm sab laug ventricle, nws txuas mus rau hauv lub plab thiab faib ua ob txoj hlab ntsha me thiab muab cov ntshav mus rau txhua qhov ntawm peb lub cev tsuas yog rau lub ntsws ntawm lub cev. Ascending ceg ntawm aorta muab ntshav rau lub plawv thaum aortic arch muab ntshav rau lub taub hau, caj dab thiab caj npab. Cov ceg uas tshwm sim los ntawm thoracic descending aorta muab cov ntshav oxygenated rau hauv siab thaum ceg ntawm lub plab aorta muab lub plab. Common iliac hlab ntsha muab ntshav rau ob txhais ceg thiab pelvis.
Dab tsi yog Artery?
Artery yog ib hom hlab ntsha uas nqa cov ntshav oxygenated los ntawm lub plawv mus rau cov ntaub so ntswg ntawm peb lub cev. Txawm li cas los xij, muaj kev zam rau qhov kev txhais no. Cov hlab ntsha pulmonary nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws rau cov pa oxygenation lossis kev ua kom huv.
Daim duab 02: Artery
Vim cov hlab ntsha nqa cov ntshav uas muaj oxygen, cov ntshav zoo li xim liab. Thiab muaj hemoglobin ntau dua. Artery phab ntsa tsim nrog peb txheej ntawm cov leeg nqaij du. Lawv yog intima, media thiab adventitiia. Cov hlab ntsha loj tshaj plaws lossis lub cev loj ntawm cov hlab ntsha yog lub aorta uas tshwm sim los ntawm sab laug ventricle ntawm peb lub siab. Aorta faib ua cov hlab ntsha me thiab faib cov pa oxygen thiab lwm yam khoom noj thoob plaws hauv lub cev tshwj tsis yog lub ntsws.
Dab tsi yog qhov zoo sib xws ntawm Aorta thiab Artery?
- Ob lub aorta thiab hlab ntsha, nqa ntshav tawm ntawm lub siab.
- Ntshav zoo li ci liab xim hauv ob lub nkoj.
- Ob Aorta thiab Artery muaj ntshav nrog oxygen siab
- Lawv yog ib feem ntawm cov hlab ntsha ntawm cov hlab ntsha.
- Cov hlab ntsha no yog tsim los ntawm cov leeg nqaij du thiab muaj peb txheej; intima, media thiab adventitiia.
- Ob leeg yog cov hlab ntsha.
Qhov txawv ntawm Aorta thiab Artery yog dab tsi?
Aorta yog cov hlab ntsha loj tshaj plaws uas nqa cov ntshav los ntawm sab laug ventricle ntawm lub plawv mus rau txhua qhov ntawm lub cev tsuas yog mus rau lub ntsws thaum cov hlab ntsha yog cov hlab ntsha uas nqa cov ntshav oxygenated thoob plaws hauv lub cev. Tsis tas li ntawd, aorta nqa cov ntshav oxygenated nkaus xwb, tab sis cov hlab ntsha pulmonary nqa oxygen-depleted carbon dioxide-nplua nuj ntshav los ntawm lub plawv. Qhov no yog qhov sib txawv tseem ceeb ntawm aorta thiab artery.
Summary – Aorta vs Artery
Ntshav circulatory system muaj lub cev (lub plawv) thiab cov hlab ntsha. Ntawm peb hom hlab ntsha, cov hlab ntsha yog ib hom. Cov hlab ntsha yog cov hlab ntsha uas nqa cov ntshav oxygenated los ntawm lub plawv mus rau lwm qhov ntawm lub cev. Txawm li cas los xij, cov hlab ntsha hu ua pulmonary artery nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws kom oxygenation thiab purification. Aorta thiab pulmonary artery yog cov hlab ntsha tseem ceeb tshaj plaws. Aorta yog cov hlab ntsha loj thiab loj tshaj plaws hauv peb lub cev. Nws pib los ntawm sab laug ventricle thiab thauj cov ntshav oxygenated mus rau tag nrho lub cev los ntawm kev ua haujlwm. Qhov no yog qhov txawv ntawm aorta thiab artery.
