Final answer:
The statement is false because hyperpnea and hyperventilation are different; hyperpnea matches oxygen demand without altering blood gases significantly, whereas hyperventilation exceeds oxygen needs and can alter blood pH.
Step-by-step explanation:
True or false: hyperpnea is another name for hyperventilation. The statement is false. While both hyperpnea and hyperventilation involve an increase in ventilation, they are distinctly different physiological processes. Hyperpnea is the increase in both rate and depth of breathing due to an increased demand for oxygen, such as during exercise or in response to certain diseases.
This adjustment does not necessarily lead to significant changes in blood oxygen or carbon dioxide levels. On the other hand, hyperventilation is characterized by an increased breathing rate that exceeds the body's requirement for oxygen, which results in lower carbon dioxide levels in the blood and could cause an increase in blood pH, making it more alkaline.
