Question

A person who travels from sea level to a high elevation will initially experience bouts of increased ventilation followed by periods of suppressed ventilation. After a day or two, ventilation will be increased without suppression. The best explanation for the initial events is

A.Arteriolaris decreased, which initiates reflexes leading to increased ventilation. Increased ventilation causes an increase in blood, which initiates reflexes leading to decreased ventilation
B.Arteriolaris decreased, which initiates reflexes leading to increased ventilation. Increased ventilation causes an increase in blood, which initiates reflexes leading to decreased ventilation
C.Arteriolaris decreased, which initiates reflexes leading to increased ventilation. Increased ventilation causes a decrease in blood, which initiates reflexes leading to decreased ventilation
D.Arteriolaris increased, which initiates reflexes leading to increased ventilation. Increased ventilation causes an increase in bloodwhich initiates reflexes leading to decreased ventilation
E.Arteriolaris increased, which initiates reflexes leading to increased ventilation. Increased ventilation causes a decrease in blood, which initiates reflexes leading to decreased ventilation

Answer 1

When traveling to high elevation, a person may initially experience increased ventilation followed by suppressed ventilation. The explanation for this is that arteriolaris decreases, which initiates reflexes leading to increased ventilation. However, increased ventilation causes a decrease in blood, which then initiates reflexes leading to decreased ventilation.

Step-by-step explanation:

When a person travels from sea level to a high elevation, they initially experience bouts of increased ventilation followed by periods of suppressed ventilation.

The best explanation for these initial events is that arteriolaris decreases, which initiates reflexes leading to increased ventilation. Increased ventilation causes a decrease in blood, which then initiates reflexes leading to decreased ventilation.
