Skeletal System

The video explores the human skeletal system, highlighting its components, functions, and types of bones. It explains the roles of different bone tissues and cells, such as osteoblasts and osteoclasts, in bone growth and remodeling. The process of bone healing after fractures is discussed, along with conditions like osteogenesis imperfecta. The video emphasizes the interconnectedness of body systems and encourages curiosity.
