1.1.a. The structure and function of the skeletal system GapFill

The skeletal system plays several important roles in the functioning of the human body. The structure of the human skeleton provides support for the body, which would otherwise struggle to remain upright during routine daily activity. The ability to remain upright leads to a further function of the skeleton in maintaining protection image posture performance .

Movement is enabled when working alongside the muscular fitness cardiovascular gas system. Bones act as levers and provide a location for bones muscles blood cells bursae to attach via tendons, causing movement at the cartilage long bone synovial joint joint capsule upon contraction. Different joint types allow for a range of movements, with ball and socket elbow hinge aerobic joints providing a greater range than hinge rotational aerobic ball and socket joints.

The skeletal system is responsible for the storage shape protection health of key minerals (e.g. calcium and phosphorus), which have many important roles in the healthy functioning of the human body.

Skeletal structures, such as the cranium surrounding the brain and the ribs humerus ulna talus surrounding the heart and lungs, play an important role in the protection health posture production of vital organs. Bone marrow found in long bones, such as the humerus in the upper arm and the tibia clavicle femur tarsal in the thigh, is responsible for the shape health protection production of blood cells – specifically, dark red white blue blood cells, which carry oxygen to the exercising muscles during aerobic respiration, and red white pathogenic pale blood cells for the immune response to infection and disease.
