Understanding Bones

The podcast episode explores the fascinating world of bones, starting with a light-hearted discussion on Halloween decorations. It answers listener questions about bone composition, growth, and healing. The hosts explain how bones are made of collagen and calcium phosphate, and how they grow from cartilage in a process called ossification. The episode also covers the bone healing process, involving cells like osteoblasts and osteoclasts. Finally, it discusses why bones last so long, touching on fossilization and preservation.
