Full Question:

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.

Explanation:

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.

The average resting heart rate (hrrest) for a 34 year old is 73 beats per minute2. 34 year old males average heart rates of 71 bpm while females average slightly higher at 76 bpm2. the normal resting heart rate range for all adults and children 10 and over is between 60 and 100 beats per minute3. 90% of 34 year olds resting pulses fall within the range of 54 to 92 bpm. in general, an adult's resting heart rate will be lower for those in better athletic condition.
