Respiratory Laws and other crap

Question 1

Dalton’s law

Answer 1

Each gas in a mixture of gases exerts a pressure proportional to the percentage of the gas.
Independently of the other gases present

Because gas molecules are so far away from each other

Question 2

How would you figure out the total pressure of a mixture of gases?

Answer 2

Add all the partial pressures of each gas up

Question 3

Boyle’s law

Answer 3

Pressure exerted by a constant number of gas molecules (at a constant temperature) is inversely proportional to the volume of the container

AKA
As container decreases in volume, pressure increases

Question 4

Henry’s law

Answer 4

Solubility of a gas dissolved in a liquid is directly proportional to the partial pressure of the gas not in the liquid

Question 5

Alveolar gas equation

Answer 5

Measures alveolar partial pressure

Question 6

Laplace’s law

Answer 6

Describes relationship between pressure (P), surface tension (T) and radius of an alveolus (r).

P = 2T/r

Surfactant ensures that small alveoli don’t collapse into bigger ones
