A homeostatic control system in human physiology consists of several key components that work together to maintain a stable internal environment. The main components of this system include the receptor (sensor), control center, and effector. These elements interact through feedback mechanisms to regulate physiological variables such as temperature, blood pressure, glucose levels, and pH.  

The receptor (sensor) is responsible for detecting changes in the internal environment. It constantly monitors physiological variables and sends information to the control center. For example, thermoreceptors in the skin and hypothalamus detect changes in body temperature, while chemoreceptors in blood vessels sense variations in oxygen, carbon dioxide, and pH ____ ______ _____ ____ _________ _________ ________ _________ ____ ____.
