Final answer:
Osteoporosis involves extensive loss of bone tissue, leading to weakened and more susceptible bones. It commonly affects certain areas of the body such as the femur, vertebrae, and wrist. Age, hormonal changes, diet, and exercise play a role in its development.
Step-by-step explanation:
Osteoporosis involves extensive loss of bone tissue. It is a bone disease characterized by reduced bone density and weakened bones, making them more susceptible to fractures. Osteoporosis commonly affects the proximal ends of the femur, vertebrae, and wrist. Factors such as age, hormonal changes, poor diet, and lack of exercise can contribute to the development of osteoporosis.
