Fill in the blank: The diagonal branches arise from the ________ artery.
left anterior descending.
Which artery supplies the posterior part of the interventricular septum?

Fill in the blank: The ________ artery runs in the interventricular groove.
left anterior descending.
Short Answer: What is the significance of collateral circulation in coronary arteries?
It provides alternative pathways for blood flow in case of blockage.
