1

What is respiration

Controlled release of energy from food

2

What are the two types of respiration

Aerobic - requires oxygen
Anaerobic- doesn't require oxygen

3

Release of energy

1) breathing - air in carbon dioxide out
2) respiration energy released from food

4

Aerobic respiration

Glucose (from food) and oxygen (from air) in
Energy, carbon dioxide and water vapour out

5

Test for CO2

Limewater
Turns from clear to milky

6

Air

Nitrogen
Oxygen
Carbon dioxide
Other gases

7

Lungs

Pleura
Bronchioles
Trachea
Bronchus
Ribs
Alveoli
Diaphragm

8

Pleura

Keeps lung lubricated to aid movement

9

Bronchioles

Carries air to and from alveoli

10

Trachea

Carries air between windpipe and lungs

11

Ribs

Protects heart and lungs

12

Alveoli

Gas exchange

13

Diaphragm

It's contacting and relaxing allows lungs to inflate and deflate

14

Breathing

1) diaphragm contracts pulling rib cage down
2) air is taken in nasal passage or mouth
3) diaphragm relaxes pushing rib cage up, air will escape

15

Gas exchange- inhaling

Oxygen removed from air in alveoli and passed to the bloodstream via capillaries

16

Gas exchange - exhaling

Carbon dioxide is exchanged from blood via capillaries into alveoli
Lungs will deflate pushing CO2 and water vapour out
