Height I believe is the correct answer
When the physician tells Dennis there may be a defect in the valve between an upper and lower chamber of his heart, he knows for sure that the defect is in the atrioventricular valve.
<h3>What are the two functions of the heart?</h3>
The two functions of the heart are as follows:
- It helps in the movement of blood throughout the body.
- It controls the rhythm and speed of the heart rate as well as blood pressure.
The Atrioventricular valve typically functions in order to prevent the blood from flowing back into the region of the atria. They are just located between the atria and the ventricles.

Mechanoreceptors
Mechanoreceptors are sensory receptors that respond to physical formations of membrane generated by touch, stretch, pressure, motion and sound. The mechanoreceptors in the cochlea of the inner ear are the most sensitive in the human body. The mechanosensory stereocilia vibrates when sound waves pass the cochlear fluid and transduce sound into nervous signal.
