Question

Boyles law can be used to explain part of the process by which air enters and leaves the lungs during breathing. Which of the following statements are true?
a. During exhalation, the diaphragm is raised, increasing the pressure in the lungs and resulting in air being forced out of the lungs.
b.A decrease in volume results in an increase in pressure.
c. During inhalation, the diaphragm is raised, increasing the pressure in the lungs and allowing air to flow into the lungs.
d. When the diaphragm is lowered, volume decreases and pressure increases.

Answer 1

The answer iiiis...C: During inhalation, the diaphragm is raised, increasing the pressure in the lungs and allowing air to flow into the lungs.

Here's Why:

When we breathe in, we're taking air from the room and temporarily storing it in our lungs. As the air is inhaled, our lungs expand; when air is exhaled, our lungs shrink back to their original state.

Answer 2

Answer:

Option (C)

Explanation:

According to Boyle's law, in any ideal gas, the pressure exerted by the gas and its volume is inversely proportional to one another, considering it to be at a constant temperature.

This law is applicable in case of respiration also. When the air is inhaled, the diaphragm is raised, as a result of which the pressure exerted on the lungs increases and eventually allows the air to flow into the lungs.

Thus, the correct answer is option (C).
