Movement requires body mechanics uses
-body mechanics = coordinated efforts of the musculoskeletal and nervous system
-Alignment and balance= posture

Mobility= ability to move about freely
Immobility: inability to move about freely
Bed Rest: an intervention that restricts clients for therapeutic reasons
Activity includes many of our bodies systems
-Skeletal system * Supports the soft tissue of the body * Protects crucial components of body * Furnishing surfaces for the attachments of muscle, tendons and ligaments * Provides storage areas for minerals and fat * Produces blood cells
-Muscular system * Motion skeletal muscle contraction pull up on tendons move bones create movments * Maintenance of posture skeletal muscles contractions hold body in stationary position * Support skeletal muscle support soft tissue in abdominal and floor of pelvic cavity * Heat production skeletal muscles contractions produce heat 1. Skeletal muscle
-works with tendons and bones to move body
-produce movement by contraction of its cells

2. Cardiac muscle 3. Smooth/visceral muscle
Nerve system
Nerve impuleses stimulus causes muscles to contract

Moblity and the body systems * Cardiovascular system
-exercise increase efficiency of heart
-decrease bp and hr
- increase blood flow to all body parts
-increase fribogen-> breaks small clots
-respiratory system and cardiac system work together to provide o2
To all part of body

Better coordination
Metabolic rate increase about 20 times with exercise
Intestinal walls increase with exercise
Exercise increase rate * Respiratory system= Reg exercise results increase in pulmonary function * Musculoskeltal system:Exercise= increase muscle tone better coordination * Metabolic process : Exercise= rate increase 20x with exercise * Gastrointestinal system:
