Exploring the Functions of the Skeleton in GCSE PE

This video is the first lesson of the Cambridge IGCSE Physical Education course, focusing on the skeletal system. It covers the four main functions of the skeleton: shape and support, movement, protection, and blood production. The lesson also names and locates the main bones, classifying them by type, and describes the functions of different bones. Key bones discussed include the cranium, clavicle, scapula, humerus, ribs, vertebrae, pelvis, femur, patella, tibia, fibula, talus, and phalanges. The video concludes with a summary of the functions of long, short, flat, and irregular bones.
