Qhov sib txawv tseem ceeb ntawm aorta thiab pulmonary artery yog aorta yog cov hlab ntsha loj tshaj plaws uas xa cov ntshav oxygenated los ntawm lub ntsws mus rau lwm lub cev thaum cov hlab ntsha pulmonary yog cov hlab ntsha uas xa cov ntshav deoxygenated mus rau lub ntsws kom huv.
Lub Plawv yog plaub-chambered leeg nqaij uas tso ntshav thoob plaws hauv lub cev. Nws muaj lub network ntawm cov hlab ntsha - cov hlab ntsha, cov hlab ntsha thiab capillaries. Aorta thiab pulmonary artery yog ob ntawm tsib lub nkoj loj uas nkag los lossis tawm hauv lub siab ncaj qha. Aorta yog cov hlab ntsha loj tshaj plaws. Nws nqa cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Pulmonary artery yog cov hlab ntsha uas pib los ntawm txoj cai ventricle thiab nqa cov ntshav deoxygenated mus rau lub ntsws kom huv.
Aorta yog dab tsi?
Aorta yog cov hlab ntsha loj tshaj plaws hauv tib neeg lub cev. Nws nqa cov ntshav oxygenated los ntawm lub plawv mus rau tag nrho tib neeg lub cev. Txij li thaum nws thauj cov ntshav aerated mus rau tag nrho lub cev, muaj ntshav siab nyob rau hauv lub aorta. Yog li ntawd, nws yog ua los ntawm cov phab ntsa tuab. Ntxiv mus, nws yog ib tug heev elastic hlab ntsha. Nws nyob rau saum lub plawv. Muaj lub aortic valve ntawm qhov nkag ntawm lub aorta los ntawm sab laug ventricle. Ntxiv mus, aorta yog ib feem ntawm cov kab ke hauv lub cev.
Daim duab 01: Aorta
Aorta faib ua ob peb cov hlab ntsha me. Cov hlab ntsha hauv qab no yog ascending thiab descending aorta, aortic arch, thiab thoracic thiab plab aorta. Ntawm lub aortic arch, muaj baroreceptors thiab chemoreceptors los saib xyuas ntshav siab. Aortic dissection, aortic aneurysm, atherosclerosis, aortic o thiab connective cov ntaub so ntswg mob yog ob peb kab mob aortic artery.
Pulmonary Artery yog dab tsi?
Cov hlab ntsha pulmonary yog cov hlab ntsha loj uas nqa cov ntshav deoxygenated los ntawm txoj hlab ntshav mus rau lub ntsws kom huv. Nws pib los ntawm txoj cai ventricle, thiab muaj pulmonary tus nqi ntawm qhov pib ntawm cov hlab ntsha. Feem ntau, cov hlab ntsha nqa cov ntshav oxygenated. Txawm li cas los xij, cov hlab ntsha pulmonary yog tib leeg hlab ntsha uas nqa cov ntshav deoxygenated.
Daim duab 02: Lub Plawv
Tsis tas li ntawd, cov hlab ntsha pulmonary nyob hauv qab lub aorta. Nws ceg mus rau sab laug thiab txoj cai tseem ceeb pulmonary hlab ntsha. Cov hlab ntsha no faib ua cov hlab ntsha me, tom qab ntawd mus rau hauv cov hlab ntsha thiab nws thiaj li mus rau hauv cov hlab ntsha. Lawv yog ib feem ntawm pulmonary ncig. Pulmonary embolisms thiab pulmonary hypertension yog ob yam kab mob pulmonary artery.
Dab tsi zoo sib xws ntawm Aorta thiab Pulmonary Artery?
- Aorta thiab pulmonary artery yog ob txoj hlab ntsha loj hauv tib neeg lub cev.
- Lawv yog ib feem tseem ceeb ntawm cov hlab ntsha.
- Ob leeg hlab ntsha nqa ntshav tawm ntawm lub siab.
- Ob leeg pib ntawm ventricles.
- Lawv tawm mus rau hauv cov hlab ntsha me me.
- Muaj kab mob aortic thiab pulmonary.
Qhov txawv ntawm Aorta thiab Pulmonary Artery yog dab tsi?
Aorta yog ib qho ntawm cov hlab ntsha loj uas nqa cov ntshav oxygenated ntawm lub plawv mus rau lwm lub cev thaum cov hlab ntsha pulmonary yog cov hlab ntsha loj uas nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws kom huv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm aorta thiab pulmonary artery. Tsis tas li ntawd, lub aorta muaj ntshav siab dua li cov hlab ntsha pulmonary.
Tsis tas li ntawd, lub aorta nyob rau saum lub plawv thaum cov hlab ntsha pulmonary nyob ncaj qha hauv qab aorta.
Cov ntawv qhia hauv qab no qhia ntau qhov sib txawv ntawm aorta thiab pulmonary artery.
Summary – Aorta vs Pulmonary Artery
Aorta thiab pulmonary artery yog ob txoj hlab ntsha tseem ceeb hauv peb lub cev. Ob leeg nqa ntshav tawm ntawm lub plawv. Txawm li cas los xij, aorta nqa cov ntshav oxygenated los ntawm lub plawv mus rau tag nrho lub cev thaum cov hlab ntsha pulmonary nqa cov ntshav deoxygenated los ntawm txoj cai ventricle mus rau lub ntsws kom huv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm aorta thiab pulmonary artery. Ntxiv mus, aorta originates los ntawm sab laug ventricle, thiab nws ceg mus rau tsib cov hlab ntsha me me thaum cov hlab ntsha pulmonary pib los ntawm txoj cai ventricle thiab nws ceg mus rau hauv ob lub ntsiab pulmonary hlab ntsha. Tsis tas li ntawd, aorta nyob rau sab saum toj ntawm lub plawv thaum cov hlab ntsha pulmonary nyob ncaj qha hauv qab lub aorta. Tsis tas li ntawd, lub aorta muaj phab ntsa tuab piv rau cov hlab ntsha pulmonary. Tsis tas li ntawd, muaj ntshav siab nyob rau hauv lub aorta. Yog li, qhov no qhia txog qhov txawv ntawm aorta thiab pulmonary artery.
