Gas exchange, hemoglobin and the delivery of Oxygen to the tissues of the body.

Explore conditions where atmospheric pressures are changed, learn about breathing under the ocean or on top of Mt. Everest, then teach your peers about what you learned Explain the problem or perhaps a unique advantage that an animal may have to deal with different partial pressures of oxygen that occur at higher elevations, or when breathing compressed air under water or in space, or when a marine mammal dives deep into the ocean.
