Laws
Boyle's Law
Henry's Law
Dalton's Law
At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.
The total pressure of a mixture of gases is the sum of the partial pressures of each gas in the mixture; it is only true for ideal gases.
volume increases pressure decreases when temperature is consistant

Gas Transport
Carbon Dioxide
Oxygen
Medullary Respiration Centers
- oxygen is inhaled and goes to alveoli
- goes to capillaries via diffusion
- transported within blood throughout body
- moves to systematic cells
- moves from systematic cells to blood via diffusion
2.transported in blood to lungs
3.diffuses into aveoli
- exhaled out of body
VRG
DRG
sends signals to diaphragm to change breathing rate
detect increase in blood ph
proprioceptors
muscles and joints activated by movement
baroeceptors
respond to stretch in lungs
