Respiration

Question 1

What is respiration

Answer 1

Controlled release of energy from food

Question 2

What are the two types of respiration

Answer 2

Aerobic - requires oxygen

Anaerobic- doesn’t require oxygen

Question 3

Release of energy

Answer 3

1) breathing - air in carbon dioxide out

2) respiration energy released from food

Question 4

Aerobic respiration

Answer 4

Glucose (from food) and oxygen (from air) in

Energy, carbon dioxide and water vapour out

Question 5

Answer 6

Nitrogen
Oxygen
Carbon dioxide
Other gases

Question 7

Lungs

Answer 7

Pleura 
Bronchioles 
Trachea 
Bronchus 
Ribs 
Alveoli 
Diaphragm

Question 8

Pleura

Answer 8

Keeps lung lubricated to aid movement

Question 9

Bronchioles

Answer 9

Carries air to and from alveoli

Question 10

Trachea

Answer 10

Carries air between windpipe and lungs

Question 11

Ribs

Answer 11

Protects heart and lungs

Question 12

Alveoli

Answer 12

Gas exchange

Question 13

Diaphragm

Answer 13

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

Question 14

Breathing

Answer 14

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

Question 15

Gas exchange- inhaling

Answer 15

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

Question 16

Gas exchange - exhaling

Answer 16

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