CENTRAL NERVOUS SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The nervous system lets your body know what is going on around you and ____
A
changes what is bad for your body.
B
maintains the conditions inside your body such as your temperature.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Nerves trigger sweat glands to release fluid that evaporates and cools the skin. Conversely, a drop in core temperature makes blood vessels constrict to conserve heat. The nervous system also triggers muscles to shiver to generate heat and warm the body.

Detailed explanation-2: -Homeostasis describes how conditions within an organism are kept constant, in order to keep cells ticking over. The nervous system is responsible for maintaining homeostasis and is made up of neurones which connect our sense organs (such as our eyes and skin) to our brain.

Detailed explanation-3: -Examples of changes include pH, temperature, salt levels, water levels, and glucose levels. For example, humans maintain an internal temperature of 98.6°F through sweating in warm temperatures and shivering in cold temperatures. These responses are homeostatic responses.

Detailed explanation-4: -The autonomic nervous system (ANS) controls cardiac and smooth muscle, as well as glandular tissue, to maintain homeostasis when the body is at rest or in an emergency.. It is associated with unconscious responses to regulate heart rate, blood pressure, body temperature, sweating and digestion.
