altitude and diving

there is less partial pressure of oxygen at

• harder for oxygen to move into your body

higher altitude

what are the short term or early adaptations to elevation change (2)

1. increased HR

2. increased RR

• because there’s less gas exchange so body makes you breath faster

what are the long term adaptations to elevation change

increased hematocrit (% of RBC’s in blood)

hematocrit increases at higher elevation becuase your making more RBC’s, so _ also increases

EPO

• this is what tells red bone marrow to make more RBC’s

_ goes into tissues at depths

nitrogen

this is what happens when you surface from diving too quickly and nitrogen in blood become out of solution (bubbly)

decompression sickness (the bends)
