Question
From what structure/vessel do the left and right coronary arteries arise?
- pulmonary trunk
- left atrium
- right atrium
- aorta
Solution
To answer the question about the origin of the left and right coronary arteries, let’s analyze the options provided:
-
Pulmonary trunk: This vessel carries deoxygenated blood from the right ventricle to the lungs and is not involved in supplying blood to the heart itself.
-
Left atrium: This chamber receives oxygenated blood from the lungs but does not give rise to the coronary arteries.
-
Right atrium: Similar to the left atrium, this chamber is involved in receiving deoxygenated blood but does not supply the coronary arteries.
-
Aorta: The left and right coronary arteries arise from the aorta, specifically from the aortic sinus just above the aortic valve.
Final Answer
The left and right coronary arteries arise from the aorta.
