Flashcards in Gas Exchange Deck (15):
1

Describe the differences between inhaled and exhaled air, ( inhaled air)

More oxygen - 21%
Less carbon dioxide - 0.04%
Nitrogen- 78%
Argon+ other gases 0.96

2

Describe the differences between inhaled air and exhaled air( exhaled )

Less oxygen 16%
More carbon dioxide 504%
Nitrogen 78%
Argon + other gases 0.96

3

Exhaled+ inhaled air word equation

Glucose+ oxygen ------ carbon dioxide+ water + energy

4

Describe the movement of ribs during inhaling and exhaling.
Air in ( active )

Rib cage moves upwards + outwards

Diaphragm moves downwards

5

Describe the movement of ribs during inhaling and exhaling.
Air out ( passive )

Rib cage moves downwards + inwards

Diaphragm moves upwards

6

Explain why these differences force air in and out ( ribs and diaphragm)

Changing the volume and pressure of the chest cavity

7

Describe features of the alveolus that make it good at its job.

1 cell thick - this allows diffusion to happen easily.

Close blood supply

8

Explain how gases move across the alveolus l/ capillary

Diffusion from high concentration to low concentration

9

Describe how to measure lung volume and which factors might affect it.

After you exercise your tidal volume will increase because your muscles work harder, your heart beats faster and you will increase the volume of air going into your lungs.

10

Write the word equation for aerobic respiration.

Glucose+ oxygen----- carbon dioxide + water

11

Write the balanced chemical equation for aerobic respiration

C6 H12 06 + 602 ---- 6C02 + 6H20

12

Describe the function of respiration

To make energy
In all cells
All the time
In all living things

13

State where in a cell aerobic respiration happens

Mitochondria

14

Explain how oxygen gets to respiring cells

By red blood cells containing harmoglobin

15

Describe the pathway of air as it moves into the lungs.

Nose
Mouth
Trachea
Bronchi tubes
Lungs
Bronchioles
Alveoli
