Qhov sib txawv tseem ceeb ntawm kev nce thiab nqis aorta yog qhov ascending aorta yog sab saud ntawm lub koov thiab ntu aortic ze tshaj plaws rau lub plawv thaum nqis aorta yog qhov qis qis ntawm lub koov uas txuas nrog lub network ntawm cov hlab ntsha. thiab muab feem ntau ntawm lub cev nrog cov ntshav uas muaj oxygen.
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 lwm qhov ntawm lub cev tsuas yog lub ntsws. Nws nyob saum lub plawv. Nws tshwm sim los ntawm sab laug ventricle ntawm lub plawv thiab yog ib feem ntawm lub systemic ncig. Muaj ob peb ntu ntawm lub aorta. Lawv yog cov ascending aorta, aortic arch, descending thoracic aorta thiab lub plab aorta. Ascending aorta yog ntu uas ze tshaj plaws rau lub plawv. Yog li ntawd, nws yog qhov sab saud ntawm lub koov thaum nqes aorta yog qhov qis ntawm lub koov.
Ascending Aorta yog dab tsi?
Ascending aorta yog thawj feem ntawm lub aorta, thiab nws tshwm sim los ntawm lub aortic orifice los ntawm sab laug ventricle thiab txuas mus rau lub aortic arch. Yog li ntawd, ascending aorta yog qhov ze tshaj plaws ntawm aorta rau lub plawv. Nws yog sab saum toj ntawm lub arch. Nws yog 2 ntiv tes ntev thiab taug kev nrog lub ntsws ntsws. Ob txoj hlab ntsha coronary (txoj cai coronary artery thiab sab laug coronary hlab ntsha) yog tib ceg ntawm ascending aorta. Ob txoj hlab ntsha no muab ntshav rau cov leeg plawv.

Dab tsi yog Descending Aorta?
Txog aorta lossis thoracic aorta yog ntu thib peb ntawm aorta. Nws kis tau los ntawm theem ntawm T4 (thib plaub thoracic vertebra) mus rau T12 (kaum ob thoracic vertebra). Lub aorta descending khiav inferiorly. Nws txuas ntxiv los ntawm lub aortic koov thiab nqis los rau hauv cov kab noj hniav thiab tom qab ntawd dhau los ua lub plab aorta.
Daim duab 02: Descending Aorta
Lub vertebral kem yog nyob tom qab ntawm lub thoracic aorta. Cov hlab ntsha bronchial, cov hlab ntsha mediastinal, cov hlab ntsha esophagal, cov hlab ntsha pericardial, cov hlab ntsha zoo tshaj phrenic, cov hlab ntsha intercostal thiab cov hlab ntsha subcostal yog cov ceg ntoo uas tshwm sim los ntawm qhov qis aorta.
Dab tsi zoo sib xws ntawm Ascending thiab Descending Aorta?
- Ascending thiab nqis aorta yog ob ntawm plaub ntu ntawm aorta.
- Ob leeg nqa oxygenated ntshav.
- Ascending aorta ua lub aortic arch thaum nqis aorta txuas ntxiv los ntawm aortic arch.
- Ob leeg muaj ceg los ntawm lawv.
Qhov txawv ntawm Ascending thiab Descending Aorta yog dab tsi?
Ascending aorta yog thawj feem ntawm lub aorta uas pib ntawm lub aortic valve, ncua 2 ntiv tes thiab dhau los ua lub aortic koov thaum nqis aorta yog qhov thib peb ntawm lub aorta uas nthuav tawm ntawm qib T4 mus rau T12 thiab dhau los ua lub plab aorta. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ascending thiab descending aorta.
Ntxiv mus, nce aorta ceg tawm mus rau ob txoj hlab ntsha coronary thaum nqis aorta ceg tawm mus rau cov hlab ntsha bronchial, cov hlab ntsha mediastinal, cov hlab ntsha oesophageal, pericardial arteries, superior phrenic hlab ntsha, intercostal thiab subcostal arteries.
Hauv qab infographic qhia qhov sib txawv ntawm ascending thiab descending aorta hauv daim ntawv tabular.
Summary – Ascending vs Descending Aorta
Ascending thiab descending aorta yog thawj thiab thib peb ntawm aorta, feem. Ascending aorta sawv ntawm lub plawv thiab yog li 2 ntiv tes ntev. Cov hlab ntsha coronary ceg tawm ntawm ascending aorta los muab lub plawv nrog cov ntshav. Qhov qis aorta khiav qis dua thiab nws txuas ntxiv los ntawm lub aortic koov thiab nqis mus rau hauv cov kab noj hniav thoracic thiab tom qab ntawd dhau los ua lub plab aorta. Nws ceg tawm mus rau ntau cov hlab ntsha uas muab ntshav rau tav thiab qee lub hauv siab. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm ascending thiab descending aorta.
