Gas Pressures
DALTON'S LAW
the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual component gases.
BOYLE'S LAW
There is an inverse relationship exists between pressure and volume.
As volume increases, the pressure of the gas decreases in proportion.
As volume decreases, the pressure of the gas increases in proportion.
GAS PRESSURES & HOW THEY ARE RELATED TO BREATHING
BLUE COLORED SIDE IS O2 POOR
Blood from capillaries to heart which transports to alveoli for exchange
RED SIDE IS O2 RICH
Blood from alveoli returns to heart which transports to tissues
Gas exchange via diffusion across a pressure gradient
Air is a mix of gases with pressure
Each type of gas contributes a partial pressure
