What does the marginal artery supply?

Answer 12

Lateral side of heart including right atrium and ventricle

Question 13

What is meant by the term end artery?

Answer 13

An artery that is the only supply of oxygenated blood to a portion of tissue.

Answer 25

The tracheobronchial, bronchopulmonary and paratracheal lymph nodes (same as lungs)
