• Produces red blood cells, and

some white blood cells

• Storage: calcium and phosphorus • Locomotion

• A ligament is a tough band of connective

Bicep

Muscles PULL on bone to make them move.

When muscles are over-worked and there is not enough oxygen available to make enough energy to

keep moving they produce lactic acid.

This will allow your muscles to

keep working with low levels of oxygen for a few more minutes.

Lactic acid is responsible for

burning sensation in

active muscles
