These systems work together to improve cardiovascular circulation, balance, coordination, posture, and even postural reflexes, which work unconsciously The physiology of activity, movement, and alignment in the body is managed through the skeletal system.

Functions of activity, movement, and alignment in the body are managed through an intertwined system of bones, muscles, and joints. Ergonomics in patient care can be accomplished through proper body mechanics such as safe lifting and transferring.

activity — purposeful movement, such as walking. body mechanics — intentional movements and muscle use designed to maintain an individual’s posture and alignment, decreasing the chance of injury. ergonomics — the design and arrangement of workspaces, tools, equipment, and tasks to optimize comfort, efficiency, and safety for employees. postural reflex — an unconscious, involuntary correction that the nervous and musculoskeletal systems make together to keep postural alignment when something threatens to disrupt it.
