Quizplus · Accepted Answer

Apnea is typically caused by a malfunction in the brain's respiratory control center, which is located in the medulla oblongata. A tumor in this area can disrupt the brain's ability to regulate breathing, leading to apnea. Lung cancer, high altitude sickness, and low red blood cell count may cause breathing difficulties, but they are not typically associated with apnea.
