Qhov sib txawv tseem ceeb ntawm cov hlab ntsha thiab cov hlab ntsha carotid yog cov hlab ntsha coronary yog cov hlab ntsha uas muab cov ntshav oxygenated rau cov leeg plawv thaum cov hlab ntsha carotid yog cov hlab ntsha loj hauv caj dab uas muab cov ntshav oxygenated rau lub hlwb thiab lub taub hau.
Cov hlab ntsha thiab cov hlab ntsha carotid yog ob lub hlab ntsha tseem ceeb uas tawm ntawm aorta. Lub plawv xav tau cov ntshav uas muaj oxygen kom muaj sia nyob thiab ua haujlwm. Coronary hlab ntsha yog cov hlab ntsha uas muab ntshav, oxygen thiab khoom noj rau lub plawv. Cov hlab ntsha carotid yog ob lub hlab ntsha loj hauv peb lub caj dab uas muab lub hlwb thiab lub taub hau nrog cov ntshav. Ob leeg coronary artery thiab carotid hlab ntsha nqa oxygen-nplua nuj ntshav. Plaque tsub zuj zuj hauv ob lub hlab ntsha ua rau muaj kab mob loj.
Cov hlab ntsha Coronary yog dab tsi?
Zoo ib yam li lwm yam kabmob, lub siab kuj xav tau cov pa oxygen thiab cov as-ham rau nws txoj haujlwm. Cov hlab ntsha coronary yog cov hlab ntsha uas muab cov ntshav oxygenated rau cov leeg plawv. Hauv lwm lo lus, cov hlab ntsha coronary yog cov hlab ntsha uas muab cov ntshav, oxygen thiab cov as-ham rau peb lub plawv. Coronary hlab ntsha qhwv ib ncig ntawm lub plawv. Yog li ntawd, cov hlab ntsha coronary yog nyob rau hauv cov hlab ntsha. Lub aorta ceg mus rau hauv ob lub loj coronary hlab ntsha raws li txoj cai coronary hlab ntsha thiab sab laug coronary hlab ntsha. Txoj cai coronary artery muab ntshav feem ntau rau sab xis ntawm lub plawv. Nws ceg mus rau txoj cai marginal hlab ntsha thiab posterior descending hlab ntsha. Sab laug coronary artery muab cov ntshav mus rau sab laug ntawm lub plawv. Nws ceg mus rau hauv ob txoj hlab ntsha raws li cov hlab ntsha circumflex thiab sab laug anterior descending artery.
Daim duab 01: Cov hlab ntsha tawg
Thaum cov hlab ntsha hauv cov hlab ntsha nqaim qis, nws txo qis cov pa oxygen thiab cov as-ham rau lub plawv cov leeg. Tus mob no hu ua kab mob coronary artery thiab nws tuaj yeem ua rau angina, plawv nres thiab txawm tuag. Cov roj (cholesterol) uas muaj cov quav hniav (plaques) thiab o yog qhov ua rau muaj kab mob coronary artery.
Carotid Artery yog dab tsi?
Cov hlab ntsha carotid yog ib qho ntawm ob txoj hlab ntsha loj uas khiav raws ob sab ntawm caj dab. Nws yog ib txoj hlab ntsha loj uas mus ntawm lub plawv mus rau lub hlwb. Nws nqa cov ntshav uas muaj oxygen rau lub hlwb, lub taub hau thiab lub ntsej muag. Zoo ib yam li cov hlab ntsha coronary, cov hlab ntsha carotid tawm ntawm lub aorta. Muaj cov hlab ntsha carotid sab laug thiab sab xis. Txhua cov hlab ntsha carotid ceg tawm mus rau hauv ob qho kev faib ua cov hlab ntsha hauv carotid thiab sab nraud carotid hlab ntsha. Cov hlab ntsha sab hauv carotid muab cov ntshav mus rau lub hlwb thaum cov hlab ntsha sab nraud carotid muab cov ntshav mus rau lub ntsej muag thiab caj dab.
Daim duab 02: Carotid Artery
Carotid noob lossis qhov txhab yog qhov nthuav dav ntawm cov hlab ntsha carotid ntawm nws cov ceg taw tes tseem ceeb. Muaj cov hlwb xws li baroreceptors thiab chemoreceptors ntawm carotid sinus. Lawv tswj cov ntshav siab. Thaum cov roj deposits txhaws cov hlab ntsha carotid, cov kab mob carotid artery tshwm sim. Nws cuam tshuam cov ntshav xa mus rau lub hlwb thiab lub taub hau. Nws ua rau muaj kev pheej hmoo mob stroke.
Dab tsi zoo sib xws ntawm Coronary thiab Carotid Artery?
- Cov hlab ntsha thiab cov hlab ntsha carotid yog ob lub hlab ntsha tseem ceeb tawm ntawm lub aorta.
- Lawv nqa thiab muab cov pa oxygenated (oxygen-nplua nuj) ntshav.
- Lawv yog ua los ntawm peb txheej ntawm cov ntaub so ntswg: intima, media thiab adventitia.
- Plaques (fatty deposits) tuaj yeem thaiv cov hlab ntsha thiab cov hlab ntsha carotid thiab thaiv cov ntshav.
Qhov txawv ntawm Coronary thiab Carotid Artery yog dab tsi?
Cov hlab ntsha muab ntshav, oxygen thiab cov as-ham rau lub plawv thaum cov hlab ntsha carotid muab cov ntshav ntau oxygen rau lub hlwb thiab lub taub hau. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm coronary thiab carotid artery. Tsis tas li ntawd, tus kab mob coronary artery yog tus kab mob cuam tshuam nrog kev nqaim ntawm cov hlab ntsha hauv lub plawv thaum cov kab mob carotid artery yog tus kab mob cuam tshuam nrog kev nqaim ntawm cov hlab ntsha carotid.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov hlab ntsha thiab cov hlab ntsha carotid.
Summary – Coronary vs Carotid Artery
Cov hlab ntsha thiab cov hlab ntsha carotid yog ob lub hlab ntsha tseem ceeb uas tawm ntawm aorta. Coronary artery muab cov ntshav uas muaj oxygen rau lub plawv thaum cov hlab ntsha carotid muab cov ntshav uas muaj oxygen rau cov bran thiab lub taub hau. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm coronary thiab carotid artery. Ob leeg nqa cov ntshav oxygenated thiab nqaim ntawm ob leeg hlab ntsha ua rau muaj kab mob vim yog kev thaiv cov ntshav rau txhua lub cev. Plaque tsim thiab o yog ob qho ua rau muaj kab mob coronary artery thiab kab mob carotid artery.
