Thermoregulation

• The hypothalamus is the main control center for thermoregulation.
• Thermoreceptors are located throughout the body, including the skin, muscles, and internal organs.
• Sweating is an important mechanism for cooling the body during exercise or hot weather.
• Warm receptors send signals to the brain when the temperature rises above normal, triggering responses such as sweating or vasodilation.
• There are two types of thermoreceptors: warm receptors (activated by temperatures above normal) and cold receptors (activated by temperatures below normal).
• Sweating is an important mechanism for cooling the body during exercise or hot weather conditions.
• Heat loss occurs through radiation, convection, conduction, and evaporation.
• Radiation involves transferring heat energy to objects with lower temperatures.
• Cold receptors detect low temperatures and initiate shivering and other mechanisms to generate heat.
• Radiation involves transferring heat from one object to another without any physical contact.
