Question 1

What is Boyles Law? What is its equation?

Answer 1

Boyles law states that in a closed system, air pressure and volume are inversely proportional, represented by the equation P1 (initial pressure) x P2 = P2 x sV2

Question 2

increase in volume = a …

Answer 2

decrease in pressure

Question 3

decrease in volume = a …

Answer 3

increase in pressure

Question 4

What is the principle of equalization?

Answer 4

the principle states that air flows from a region of higher pressure to a region of lower pressure

Question 5

what happens if we create a low pressure in our thoracic cavity?

Answer 5

air will draw in unless we have the cavity is closed via the glottis

Question 6

how is low pressure created in the thoracic cavity?

Answer 6

during inhalation, lung volume increases, creating pressure lower than atmospheric pressure, causing air to flow into the lungs.

Question 7

why do the lungs not move themselves?

Answer 7

there are no muscles in the lungs. there are no connections between the lungs and the ribcage via muscles ligaments etc.

Question 8

What is tidal breathing? how much of our lung capactiy do we inhale and exhale?

Answer 8

when you arent talking or focusing on your breathing. normal shallow breathing. we inhale and exhale about 40% of our capacity.

Question 9

what is IRV (inspiratory reserve volume)

Answer 9

this is the maximum amount of air you can take at a time after yout tidal breath is inhaled.
