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: -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. Another important function of the skin is body temperature regulation.

Detailed explanation-4: -The functions of the skin include: Protection against microorganisms, dehydration, ultraviolet light, and mechanical damage; the skin is the first physical barrier that the human body has against the external environment.

Detailed explanation-5: -The skin’s immense blood supply helps regulate temperature: dilated vessels allow for heat loss, while constricted vessels retain heat. The skin regulates body temperature with its blood supply. The skin assists in homeostasis. Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss.
