A nursing instructor asks a nursing student to describe the structure and function of the coronary arteries. Which response by the student indicates a need for further research on the anatomy and physiology of the heart?

1. "The coronary arteries branch from the aorta."

2. "The coronary arteries supply the heart muscle with blood."

3. "The left coronary artery provides blood for the left atrium and the left ventricle."

4. "The left coronary artery supplies the right atrium and right ventricle with blood."

"The left coronary artery supplies the right atrium and right ventricle with blood.""The left coronary artery supplies the right atrium and right ventricle with blood." indicates a need for further teaching on the anatomy and physiology of the heart.

Heart plays a major role in the survival of humans. A muscular organ that is around the closed fist size is the heart. The heart helps in pumping blood to various human parts. When the contraction of the heart occurs, the blood will be pumped to various parts of the human body.

The deoxygenated blood is carried to the lungs where it includes oxygen and excludes carbo dioxide. This carbon dioxide is considered as the waste product obtained from metabolism. The anterior descending artery and the circumflex artery that provides blood to the left atrium and left ventricle is divided by the left coronary artery. The right atrium and the right ventricle is supplied by the right coronary artery.
