Calcium is essential for the development and maintenance of what in the body?

skin and muscle
bones and teeth
blood and organs
nerves and hormones

The correct answer is: bones and teeth

Calcium is crucial for the development and maintenance of bones and teeth due to its role as a primary mineral constituent in these structures. Bone tissue, for instance, is predominantly made up of calcium phosphate, which gives bones their strength and rigidity. Adequate calcium intake during childhood and adolescence is essential for peak bone mass development, while sufficient calcium in adulthood is vital for maintaining bone density and preventing conditions such as osteoporosis. Teeth also contain a significant amount of calcium, contributing to their structure and resilience against decay. The calcium in teeth, along with other minerals, helps to form the enamel, dentin, and cementum, which are essential for dental health. While calcium plays roles in other bodily functions, such as nerve signaling and blood coagulation, its fundamental importance lies in supporting the structure and health of bones and teeth. This highlights why it is often emphasized in dietary guidelines related to bone health.
