1

What are the 4 gas laws?

Boyle's law

Dalton's law

Charles' law

Henry's law

2

What does Boyle's law state?

Pressure exerted by a gas is inversely proptional to its volume (P = 1/V)

3

What does Dalton's law state?

Total pressure of a gas mixture is the sum of the pressures of the individual gases

4

What does Charles' law state?

Volume occupied by a gas is sirected related to the absolute temperature (V directly proportional to T)

5

What does Henry's law state?

Amount of gas dissolved in a liquid is determined by the pressure of the gas and its solubility in the liquid

6

When talking about the pressure and volumes of gas, what does the volume refer to?

The volume of the container that the gas is in

7

What is core body temperature?

37oC

8

What is ventilation?

Movement of air in and out of the lungs

9

In terms of pressure, where does air always move?

From areas of high pressure to areas of low pressure

10

If the pressure in the lungs is more than the atmosphere, where does the air move?

From the lungs to the atmosphere (out of the body)

11

What shape is the diaphragm?

Domed shaped

12

What happens when the diaphragm contracts?

It flattens which increases the volume of the thoracic cavity

13

How many lobes does the right and left lung have?

Right has 3 lobes

Left has 2 lobes

14

What are the lobes in the right lung called?

Superior lobe

Middle lobe

Inferior lobe

15

What are the lobes of the left lung called?

Superior lobe

Inferior lobe

16

What is the pleural cavity critical for?

Maintaining the inflation state of our lungs

17

What is A?

Aorta

18

What is B?

Left lung

19

What is C?

Pleural membranes

20

What is D?

Left pleural cavity

21

What is E?

Pericardial cavity

22

What is F?

Right pleural cavity

23

What is G?

Right lung

24

What is H?

Esophagus

25

What does the pleural cavity contain?

5mm of pleural fluid

26

What is the pleural cavity unique to?

Each lung, they do not join

27

What does the inside and outside of the pleural membrane line?

Ribs and outer tissue of the lungs

28

What are the 2 pleural membranes called?

Visceral pleural membrane (lines lungs)

Parietal pleural membrane (lines ribs)

29

What does the visceral pleural membrane line?

Lungs

30

What does the parietal pleural membrane line?

Ribs
