AP PSYCHOLOGY

Detailed explanation-1: -The blood flow to your skin decreases, and you might start shivering so that your muscles generate more heat. You may also get goose bumps-so that the hair on your body stands on end and traps a layer of air near your skin-and increase the release of hormones that act to increase heat production.

Detailed explanation-2: -When the hypothalamus senses that you’re too cold, it sends signals to your muscles that make your shiver and create warmth. This is called maintaining homeostasis. The hypothalamus also maintains homeostasis in lots of other ways, such as by controlling your blood pressure.

Detailed explanation-3: -A Thing Called Homeostasis 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-4: -If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body.

Detailed explanation-5: -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.
