Final answer:
High Altitude Cerebral Edema (HACE) primarily affects the brain, not the heart. HACE is a severe form of altitude sickness that occurs when there is a swelling or edema in the brain due to exposure to high altitudes with low oxygen levels.
Step-by-step explanation:
False. High Altitude Cerebral Edema (HACE) primarily affects the brain, not the heart. HACE is a severe form of altitude sickness that occurs when there is a swelling or edema in the brain due to exposure to high altitudes with low oxygen levels. The lack of oxygen can cause fluid to accumulate in the brain, leading to symptoms such as headache, confusion, loss of coordination, and in severe cases, coma and death.
