Q

Why is it hard to breathe at the top of a mountain?

A

Because the air pressure is lowe4

Hence, the partial pressure is lower

The same partial pressure already inside your lungs.

Making gas exchange difficult

17
Q

Which process does the respiratory system use to facilitate gas exchange in and out of the lungs

A

Ventilation

18
Q

External respiration is …..

Internal respiration is….

A

Between the lungs and the environment

Between the blood vessels and the cells

19
Q

Inhaled oxygen travels down through the trachea, into the right and left bronchus, then into the Segmental Bronchi which branches further into the Lobar Bronchi.

A

False

Travels down through the Trachea, into the right and left Bronchus, then into Lobar Bronchi which branches even further into Segmental Bronchi

A

Pharynx & Nasal Cavities

21
Q

T or F

A

F

Inhalation: the diaphragm contracts Downwards to create Negative pressure
