Learning objective A
Function of the skeletal system
Support
Protection
Attachment for skeletal muscle
source of blood cell production
Store of minerals
Store of minerals
Leverage
Weight bearing
Reducing friction across joints zzz
Response of skeletal system to exercise
(LT) Increase ligaments Strength and pliability
(ST) Increased production of synovial fluid- lubricates joints
(ST) Synovial fluid becomes less viscous
(ST) Increase uptake of minerals
(LT) Increased bone density
