How does the body react to cold temperature?
Options:
Your body sweats to help it maintain homeostasis
Your body shivers to make the internal temperature balanced with the external environment
You body sweats to make the internal temperature balanced with the external environment
Your body shivers to help it maintain homeostasis
Your body shivers to help it maintain homeostasis
The correct option is: Your body shivers to help it maintain homeostasis.
When the body is exposed to cold temperatures, it initiates several physiological responses to help maintain internal body temperature. One of these responses is shivering. Shivering is an involuntary reflex that causes rapid muscle contractions. These contractions generate heat, allowing the body to compensate for the heat loss to the cold environment and maintain its internal temperature. Shivering is part of the body's natural mechanism to maintain homeostasis, or the stable internal environment necessary for optimal functioning.
The correct option is:
- Your body shivers to help it maintain homeostasis.
When exposed to cold temperatures, our body reacts in different ways to maintain its core temperature and ensure optimal functioning. One of the main responses to cold temperature is shivering. Shivering is an involuntary muscular contraction that generates heat and helps to balance the internal temperature with the external environment.
To understand why shivering helps maintain homeostasis, it's important to know that our body strives to maintain a steady core temperature of around 98.6°F (37°C). When exposed to cold temperatures, thermoreceptors in the skin and other tissues detect the drop in temperature and send signals to the brain.
The brain then initiates a response by activating the muscle fibers to rapidly contract and relax. This generates heat through muscular work, which helps to raise the body's temperature and counteract the cold.
In addition to shivering, another response to cold temperature is vasoconstriction. This is when the blood vessels near the skin's surface constrict, reducing blood flow and preventing heat loss. It helps to preserve warmth by redirecting the blood to vital organs in the core of the body.
So, while sweating is a response of the body to heat in order to cool down, shivering is the response to cold temperature to generate heat and maintain homeostasis by balancing the body's internal temperature with the external environment.
