When we overuse a joint, the bursae become inflamed, resulting in bursitis, a condition in which the bursae lose their function and the movements become painful. Excessive use of some joints can cause bursitis in sports like cycling, tennis, and long-distance running.
The ability of an organism to maintain its internal stability against external environmental changes thereby developing the constant internal environment within the organism is known as Homeostasis.
Homeostasis is deeply produced in warm-blooded animals to control body temperature, fluid balance, blood pH, and oxygen pressure, concentration of chemicals,etc.
During homeostasis process entire body system work together to maintain the balance. If not controlled or if disrupted the process will result in disease or disorder.
