Q

What happens at stage 2 of journey of air to the body?

A

(Gaseous exchange in the lungs)

Capillaries -> oxygenated blood circulated from the lungs to the heart -> pulmonary vein enters left atrium, moves to left ventricle -> circulated to body via aorta, arteries,arterioles, capillaries.

17
Q

What happens at stage 3 of the journey of air to the the body?

A

Oxygen reaches the cells

18
Q

What happens at stage 4 of the journey of air to the body?

A

(Gaseous exchange -body cells)

Cells receive oxygen and release carbon dioxide into capillaries -> deoxygenated blood travels to the heart (venues, veins, vena cava) -> enters the right atrium, moves to the right ventricle -> circulated to the lungs (pulmonary artery, arterioles, capillaries)

19
Q

What happens stage 5 of journey of air to the body?

A

(Gaseous exchange in the lungs)

Alveoli receive carbon dioxide from capillaries and releases oxygen into capillaries -> bronchioles, bronchus -> larynx, pharynx -> nose, mouth.

20
Q

What happens at stage 6 of the journey of air to the body?

A

Breathe out
