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.

A myocardial infarction (2) has occurred with blockage of a branch of the left coronary artery (1). Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.

Answer:
Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, it's estimated that you need to burn about 3,500 calories to lose 1 pound. So, in general, if you cut about 500 to 1,000 calories a day from your typical diet, you'd lose about 1 to 2 pounds a week.
That hormone would be glucagon
