A mountain climber ascends to a very high altitude where the atmospheric pressure is significantly lower. How does this situation primarily threaten their survival?
A mountain climber ascends to a very high altitude where the atmospheric pressure is significantly lower. How does this situation primarily threaten their survival?
- Dehydration due to rapid water loss
- Impaired oxygen intake (correct)
- Reduced nutrient absorption
- Inability to regulate body temperature

Study Notes
- Survival needs are essential requirements for the body to stay alive.
Nutrients
- Nutrients from food provide energy and help build cells.
- Proteins aid in muscle development.
- Carbohydrates are a source of energy.
Oxygen
- Oxygen is needed to break down food and release energy.
- Cells cannot function without oxygen.
Water
- The body is mostly water.
- Water facilitates chemical reactions.
- Water helps transport nutrients and waste.
Normal Body Temperature
- A body temperature of about 98.6°F (37°C) is needed for chemical reactions to occur correctly.
- The body may not function correctly if it is too hot or too cold.
Atmospheric Pressure
- Atmospheric pressure refers to the air pressure.
- The lungs require the right pressure to take in oxygen and remove carbon dioxide.
