Question

Pick 7 factors from the list below that can raise respiratory
rate:

Answer 1

Factors that can increase the respiratory rate include metabolic acidosis, exercise, hyperventilation, high altitude conditions, psychological stress, increased body temperature, and hyperpnea related to exercise. These factors stimulate the respiratory centers of the medulla oblongata and pons to meet the body's oxygen demands and carbon dioxide removal needs.

Step-by-step explanation:

The question asks us to identify factors that can raise the respiratory rate. The respiratory rate is the number of breaths taken per minute, and is an important measure of pulmonary function. From the provided list, seven factors that can increase respiratory rate are:

1. Metabolic acidosis which leads to an increase in carbon dioxide.
2. Exercise, which increases oxygen demand and carbon dioxide production.
3. Hyperventilation, where there is an increased depth and rate of breathing.
4. High altitude conditions, which may lead to a higher respiratory rate to compensate for lower oxygen levels.
5. Psychological stress, often increasing the rate of breathing.
6. Increased body temperature, as the metabolic rate increases, so does the need for oxygen and removal of carbon dioxide.
7. Hyperpnea related to exercise, which is an increase in the depth and rate of breathing.

These factors influence the mechanism of breathing, which is controlled by the respiratory centers of the medulla oblongata and pons. The increased stimuli received by these centers result in an increase in respiratory rate to meet the body's demand for oxygen and necessity for carbon dioxide removal.
