The human body normally maintains a set body temperature. How does this happen? How do we generate additional heat when our body is too cold, and how do we cool off when we are too hot? Although part of this response is voluntary, how do we really know that we are cold, and what is our brain doing involuntarily to keep temperatures constant. At times our temperature will move away from the set point, whether through environmental effects such as exposure to cold or internal processes including fever and exercise.
Humans are homeotherms, maintaining an average core temperature of 37 +/- 0.5 degrees Celsius. Core temperature varies slightly due to environmental and metabolic factors. Exercise or fever may raise core temperature by up to three degrees, while exposure to cold may lower core temperature by a degree. Beyond these boundaries, the human is susceptible to heat stroke (elevated temperature) or hypothermia, both of which are life threatening conditions.
While core temperature is tightly regulated, skin temperature varies greatly in response to metabolism and the environment. Temperature receptors in the skin (cold and hot) detect these changes, initiating compensatory mechanisms through the central nervous system.
The hypothalamus, located in the brain, is the primary organ that regulates body temperature. It acts as the body's thermostat, receiving signals from the body and adjusting mechanisms such as sweating or shivering to maintain a stable internal temperature.
The brain is part of the nervous system, which controls or monitors all of the other organ systems.
The skin is the sense organ we primarily use for the sense of touch or feel. It contains various receptors that detect pressure, temperature, and pain, sending signals to the brain for interpretation.
The sense organ used for feeling is the skin. The skin contains receptors that can detect pressure, temperature, pain, and touch, allowing us to sense our environment and feel different sensations.
The skin is the largest sense organ in the human body as it covers and protects the entire body. It contains sensory receptors that allow us to feel touch, pressure, temperature, and pain.

The skin is the body's largest organ. It serves as a protective barrier against external elements, helps regulate body temperature, and contains sensory receptors for touch, temperature, and pain.

The pouch of skin that contains the testes is called the scrotum.
The organ that contains the villi is the small intestine.
Root organ contains root hair tissues
The genitourinary system.

There is no such organ.
