Verified step by step guidance

Understand the function of the scrotum: The scrotum is responsible for regulating the temperature of the testes, which is crucial for sperm production and overall reproductive health.

Consider the effect of warmth: When exposed to warmth, the scrotum needs to ensure that the testes remain at an optimal temperature, which is slightly cooler than the body's core temperature.

Analyze the physiological response: In response to warmth, the scrotum will increase its surface area to dissipate heat more effectively. This is achieved by relaxing the muscles within the scrotum, allowing it to become less wrinkled and more stretched out.

Evaluate the options: The correct physiological response to warmth is to increase the surface area, which helps in cooling down the testes. This is contrary to pulling the testes closer to the body, which would occur in response to cold.

Conclude the reasoning: The scrotum increases its surface area in response to warmth to maintain the optimal temperature for the testes, ensuring proper function and health.
