The term yardstick refers to what is a normal response. It really has nothing to do with a yardstick and can be used in many situations. A yardstick is a measurement that has been tested over and over and than that measurement becomes the standard.

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.
Therefore, a defect in the atrioventricular valve is found when Dennis suffers from a defect in the valve between an upper and lower chamber of his heart.
