Bone is a hard, dense tissue that makes up the skeleton of humans and many animals. It provides structure, support, and protection for vital organs. Bones also play a crucial role in producing blood cells and storing minerals like calcium and phosphorus, which are essential for various bodily functions. There are different types of bones in the body, such as long bones like the femur, short bones like the carpals, and flat bones like the skull. Each type has a unique shape and function, contributing to the overall strength and flexibility of the skeletal system.
