During exercise, your body releases heat by a) using stored energy b) increasing breathing c) deceasing heart rate d) dilating blood vessels

Step 1: Define the Problem

Identify which mechanism the body uses to release heat during exercise.

Step 2: Break Down the Problem

Evaluate each option to determine how it contributes to heat release:

• a) Using stored energy
• b) Increasing breathing
• c) Decreasing heart rate
• d) Dilating blood vessels

Step 3: Apply Relevant Concepts

• Using stored energy: This is primarily for fueling exercise, not directly for heat release.
• Increasing breathing: Helps in oxygen exchange but not directly related to heat release.
• Decreasing heart rate: This would reduce blood flow, not aiding in heat release.
• Dilating blood vessels: Known as vasodilation, this increases blood flow to the skin, facilitating heat loss.

Step 4: Analysis, Verify and Summarize

• Dilating blood vessels (vasodilation) is a physiological response to increase heat dissipation by allowing more blood to flow near the skin's surface, where heat can be released into the environment.

Final Answer

d) dilating blood vessels
