Answer is Wrong!
Answer is Right!
The correct answer is B. Perspiration system.
The perspiration system is a part of the human temperature control system. When the body temperature rises, the hypothalamus sends a signal to the sweat glands to produce sweat. The sweat then evaporates from the skin, which cools the body.
The digestive system is responsible for breaking down food and absorbing nutrients. It is not involved in temperature control.
The ear is responsible for hearing and balance. It is not involved in temperature control.
Leg movement is involved in locomotion. It is not involved in temperature control.
The perspiration system is the only system that is involved in temperature control.
