Respiratory Quiz

Which is the correct order of the respiratory pathway?

• Mouth/Nose- Trachea-Bronchioles-Bronchi-Alveoli

• Mouth/Nose-Trachea-Bronchi-Bronchioles-Alveoli

• Mouth/Nose-Trachea-Bronchi-Cilia-Alveoli

• Mouth/Nose-Trachea-Bronchi-Cilia-Diaphragam

What traps and filters dust particles that enter the trachea?

What happens during gaseous exchange?

• Carbon dioxide and oxygen move down a concentration gradient.

• Oxygen diffuses into the capillaries

• Carbon dioxide diffuse into the alveoli to be taken away and expired

• Trachea is stopped from collapsing by rings of cartillage.

• Intercostal muscles relax and diaphragm returns to starting position.

Oxygen = Haemoglobin =

Which of these are factors that affect diffusion?

• Alveoli are small in size and large in quantity.

• Alveoli and capillaries are very thick.

• Alveoli and capillaries are touching each other so little distance to travel.

• Alveoli are dry so diffusion is easier
