At high altitudes, the partial pressure of oxygen is lower. How might you expect this lower oxygen level to affect the ability of the blood to transport respiratory gases, and what would be the effect on respiring tissues?
Jumping into cold water may initiate the “diving reflex,” during which blood is shunted toward the head and away from the limbs. Under these conditions, why might you be able to hold your breath for an extended period?
The following diagram shows a lung with a large shunt
in which mixed venous bypasses the oxygen exchange
areas of the lung. Breathing room air produces the
oxygen partial pressures shown on the diagram. What
is the oxygen tension of the arterial blood (in mm Hg)
when the person breathes 100% oxygen and the
inspired oxygen tension is over 600 mm Hg?
PO₂ = 40 mm Hg
A) 40
B) 55
C) 60
D) 175
E) 200
F) 400
G) 600
PO₂ = 104 mm Hg
PO₂ = 55 mm Hg
