which belongs to each sentence?
In [external/ or cellular] respiration, these
gases are exchanged between the body's tissues and the outside
environment by way of the respiratory system. In [
external/ or cellular] respiration, these gases are used
and created by the metabolic processes of the cells.
[alveolar capillary membranes, type 2 alveolar cells,
type 1 alveolar cells] make up the main structure of the
alveolar wall. The walls of the alveoli are very thin,
separated from the capillary vessels by...

A mountain climber ascends to an altitude where the partial
pressure of oxygen in the atmosphere is very low.
a. What happens to the climber’s ventilation rate?
b. Which chemoreceptor (oxygen or carbon dioxide/pH) would cause
this change in ventilation rate at high altitude? Your answer
should reflect that you know the stimuli for change in ventilation
rate under different conditions

The
atmosphere is a giant sedimentation equilibrium experiment.
Nitrogen and oxygen are pulled down by the gravitational potential,
and diffuse back upwards due to entropy. Assuming the earth’s
gravitational acceleration is uniform and 9.802 m s–2, and the
average temperature of the atmosphere is –20°C, and the pressure of
N2 and O2 at sea-level are 0.79 and 0.20 bar respectively,
calculate the pressure of nitrogen and oxygen at the elevation of a
transatlantic airplane flight (10 km).
