The answer to both questions is yes.
Explanation:
The heart has two atria that receive blood returning to the heart:
- left atrium: receives blood from the lung circulation
- right atrium: receives blood from the body circulation
The coronary arteries are branches of the aorta and supply the myocardium (heart muscle) with oxygen rich blood.
