MICROANATOMY

Detailed explanation-1: -Shivering-nerve impulses are sent by the hypothalamus to the skeletal muscles to bring about rapid contractions that generate heat. Shivering therefore helps raise the body temperature. Increase in metabolic rate-the liver produces extra heat in order to raise the temperature of the body.

Detailed explanation-2: -When the air is super cold, it will take away your body heat, leaving you feeling – you guessed it – cold! As part of the process of homeostasis, shivering is one way that your body tries to produce more warmth and make up for all the heat it’s losing to the cold air.

Detailed explanation-3: -Shivering is muscle activity that generates heat and warms the body. Similarly, some insects vibrate their wings for a while before flight, heating the muscles to the temperature at which they work best. When an animal shivers in the cold, a large amount of heat is generated in the muscles.

Detailed explanation-4: -When exposed to cold temperatures, your body begins to lose heat faster than it is produced. Prolonged exposure to cold will eventually use up your body’s stored energy. The result is hypothermia, or abnormally low body temperature.
