Question

summarize this The nicotine in cigarettes slows the production of bone-forming cells (osteoblasts) so that they make less bone. Smoking decreases the absorption of calcium from the diet. Calcium is necessary for bone mineralization, and with less bone mineral, smokers develop fragile bones (osteoporosis).

Answer 1

Nicotine in cigarettes reduces the production of bone-forming cells and decreases the absorption of calcium from the diet, leading to weaker and more fragile bones in smokers. This can ultimately result in osteoporosis.
