Question 1

What happens during Respiration

Answer 1

oxygen and carbon dioxide are exchanged

Question 2

What does Oxygen help sustain?

Answer 2

helps to sustain our body’s cells

Question 3

How is air pressure measured as?

Answer 3

as the force exerted on a chamber by air molecules

Question 4

What is the formula for pressure ?

Answer 4

Pressure = Force/Area; P = F/A

Question 5

BOYLE’S LA

Answer 5

if A ↑ then P ↓ and if A ↓ then P ↑
When applied to the lungs this means that as the lungs expand (and their volume ↑) then the air pressure in the lungs ↓
If you increase the volume then the pressure will decrease

Question 6

Piston Analogy

Answer 6

hypodermic needle

Question 7

What happens if we decrease in pressure?

Answer 7

itll cause air to enter in the lungs to balance it out

Question 8

in nature what is the spontaneous tendency we seek?

Answer 8

there exists a spontaneous tendency to seek equilibrium

Question 9

What happens when the lungs expand?

Answer 9

as the lungs expand they create a difference in air pressure between the region internal and the region external to the lungs
then Air then rushes into the lungs in order to stabilize the difference in air pressure

Question 10

ribcage

Answer 10

Is where the lungs are situated and ribcage serve to protect and support them
