Which organ system functions to protect the body from exposure and can help to regulate temperature?

The urinary system, which includes the kidneys, ureters, bladder, and urethra, is responsible for removing waste from the body and maintaining the body's electrolyte balance. It does not have a direct role in protecting the body from exposure or regulating temperature.

The lymphatic system, consisting of the lymph nodes, lymphatic vessels, tonsils, thymus, and spleen, is primarily responsible for immunity. It transports and filters lymph fluid containing antibodies and lymphocytes (good) and bacteria (bad). While it does protect the body from disease, it does not directly protect against environmental exposure or regulate temperature.

The nervous system, which includes the brain, spinal cord, and nerves, controls the body's responses to internal and external stimuli. While it does play a role in temperature regulation by signaling the body to sweat or shiver, it does not directly protect the body from exposure.
