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.

Mike's intrapulmonary pressure must be lower than atmospheric pressure when he inhales and greater than atmospheric pressure when he exhales in order to maintain normal air flow during inhalation and exhalation when he is having one of his asthma attacks.
The pressure exerted by gases within the alveoli of the lungs is called as intrapulmonary pressure.
To secure the normal air flow, the pressure gradient increases as airway resistance also increases. The pressure gradient is the difference between intrapulmonary and atmospheric pressures.
During inhalation, the intrapulmonary pressure must decrease more than average so that air is carried into the lungs against a greater resistance. However, during exhalation, the intrapulmonary pressure must increase more than normal to move out the air against the same resistance.

Answer:
lower than Ray's
Explanation:
The reason while Louisa's recommendations will be lower than that of Ray's is because after evaluating the amount of recess time that should be given for the next school year, as a new combined school from school A and school B, Louisa has a report which shows over the previous years, children have no recess time in school, while Ray has a report that shows each day children have 60 minutes of research. This will be the reason why her report will be lower than that of Ray's.
