An Invasion of a pathogen leads to infection: causing destruction and weakening of the bone.
A decrease in blood supply to the bone results in bony necrosis or the death of bone cells.
Increased amounts of estrogen in postmenopausal women contribute to bone loss.
The Correct Answer is A
A. There is an imbalance between the formation of new bone and the resorption of existing bone: Osteoporosis occurs when bone resorption outpaces bone formation, leading to decreased bone density and increased susceptibility to fractures.
B. An invasion of a pathogen leads to infection, causing destruction and weakening of the bone: This describes osteomyelitis, a bone infection, not osteoporosis.
C. A decrease in blood supply to the bone results in bony necrosis or the death of bone cells: This describes avascular necrosis, not osteoporosis.
D. Increased amounts of estrogen in postmenopausal women contribute to bone loss: In fact, decreased estrogen levels after menopause contribute to bone loss and osteoporosis.
