MICROANATOMY

Detailed explanation-1: -Endotherms have various ways of increasing metabolic heat production, or thermogenesis, in response to cold environments. One way to produce metabolic heat is through muscle contraction-for example, if you shiver uncontrollably when you’re very cold.

Detailed explanation-2: -Another adaptation to control body temperature that endotherms have is the ability to shiver. This involuntary movement of your muscles when you get cold Page 2 burns calories. Heat is released. Shivering helps keep your body warm.

Detailed explanation-3: -Endotherms generate heat within themselves through metabolic processes. This allows their body temperature to stay constant, even when the temperature of their environment fluctuates. This is why endotherms are known as, “warm-blooded:” because their warmth comes from within themselves.
