Which system acts as a barrier against infection and UV radiation and helps regulate body temperature?
A
integumentary
B
muscular
C
digestive
D
cardiovascular
Explanation: 

Detailed explanation-1: -Your integumentary system acts as a physical barrier-protecting your body from bacteria, infection, injury and sunlight. It also helps regulate your body temperature and allows you to feel skin sensations like hot and cold.

Detailed explanation-2: -The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails. In addition to its barrier function, this system performs many intricate functions such as body temperature regulation, cell fluid maintenance, synthesis of Vitamin D, and detection of stimuli.

Detailed explanation-3: -Sweat glands in the skin allow the skin surface to cool when the body gets overheated. Thermoregulation is also accomplished by the dilation or constriction of heat-carrying blood vessels in the skin.

Detailed explanation-4: -The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses.

Detailed explanation-5: -One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature. The skin contains secretions that can kill bacteria and the pigment melanin provides a chemical pigment defense against ultraviolet light that can damage skin cells.
