Chapter 38, Problem 10SQ
Summary Introduction
Concept introduction: The delivery of oxygen to the cells plummets when the people who live at low altitude ascend too fast to a high altitude. Cellular oxygen deficiency or hypoxia is the result of this case. The people who stay in high altitudes for a long time have adaptations that allow them to function in a low-oxygen environment. The physiological change that occurs in response to high altitude is called acclimatization.

Students have asked these similar questions
Some deep diving mammal compress their lungs to remove air. What is FALSE about this
situation?
A. Some whales have ribs with joints that help the compression.
B. Removing air from lungs prevents lethal nitrogen bubbles (the bends).
C. The animals store 02 in their blood and muscles during dives
D. The air goes from their lungs into tiny spaces within their bones.
Which is biggest?
A. hemoglobin
B. iron
C. heme
oxygen binding to hemoglobin has what affect on additional molecule of oxygen binding to the dame molecule of hemoglobin?
a. decreases teh binding of more oxygen to that molecule of hemoglobin.
b. increases the binding of more oxygen to that molecule of hemoglobin.
c. has no effect on the ninding ofm ore oxygen to that molecule of hemoglobin
d. this is a trick question becuase only one oxygen can bind to a molecule of hemoglobin.
Pulmonary edema can occur at high altitude this is happening because
a. Of the swelling of the brain
b. Of the leakage of fluid out of capillaries in the lung
c. The blood pressure has dropped to low
d. Of the shortage of breath
