The cardiovascular system of a mouse works like that of a human.A mouse is moved from sea level (low altitude)to the top of a mountain (high altitude).How could this mouse's cardiovascular system maintain a similar rate of oxygen delivery to its tissues now that the mouse is at the top of the mountain?
A)Decrease breathing rate.
B)Decrease heart rate.
C)Increase the depth of ventilation.
D)Increase lung pressure.

Quizplus · Accepted Answer

Increasing the depth of ventilation would allow the mouse's lungs to take in more oxygen with each breath and thus maintain a similar rate of oxygen delivery to its tissues despite the decrease in atmospheric oxygen levels at high altitude. Decreasing breathing rate or lung pressure would not necessarily increase the amount of oxygen taken in with each breath, and decreasing heart rate could actually result in a decrease in oxygen delivery to the tissues.
