What do the coronary arteries supply?Multiple choice question.aortaheart myocardiumlung tissue

Breaking Down the Problem

1. We need to identify which option correctly describes what the coronary arteries supply.

Relevant Concepts

2. Coronary arteries are responsible for supplying blood to the heart muscle (myocardium). They originate from the base of the aorta and branch out to deliver oxygen-rich blood to the myocardium.

Analysis and Detail

3. Let's analyze the options provided:
   • Aorta: This is the main artery that carries blood away from the heart, not supplied by the coronary arteries.
   • Heart: The heart itself is an organ, but the specific part supplied by the coronary arteries is the myocardium.
   • Myocardium: This is the actual heart muscle that contracts to pump blood; it is indeed supplied by the coronary arteries.
   • Lung tissue: The lungs receive blood through the pulmonary arteries, not the coronary arteries.

Verify and Summarize

4. The correct answer is related specifically to the heart muscle. The coronary arteries play a crucial role in supplying oxygenated blood to the myocardium, essential for proper heart functioning.

Final Answer

The coronary arteries supply myocardium (the heart muscle).
