Answer 4

Occurs at the surface of the alveoli in the lungs. The walls of the alveoli are moist and only one cell thick, gases can diffuse and move easily across them

• oxygen is absorbed into the blood from
• inhaled air
• carbon dioxide leaves the blood and to leave in exhaled air

Question 5

Question 7

Diaphragm location

Answer 7

Is under lungs and stretch across chest cavity

The intercostal muscles are attached to rib cage

Question 8

Breathing in

Answer 8

Diaphragm and intercostal muscles contract causing the ribs to rise and expand and gut to drop
Low pressure forms in lungs sucking air into lungs

Question 9

Breathing out

Answer 9

Diaphragm and intercostal muscles relax allowing ribs to decrease and gut to life
High pressure pushes air out of lungs

Question 10

Inhaled and exhaled air

Answer 10

Inhaled contains more oxygen

Exhaled contains more carbon dioxide
