I will understand the function of the muscular system.

2. Fxn of Skeletal Muscle:
Movement
Heat Production
Posture

3. Movement attached to bone contracts thus producing movement
Ex: walking, talking, chewing, blinking

4. Heat Production Reactions during muscle contraction produce heat
Heat contributes to constant body temperature (homeostasis of temperature)

5. Why do we shiver when we're cold?
Shivering is a result of muscle contraction. This produces heat thus increasing your body temperature.

6. Posture Continuous partial contraction of skeletal muscles
Allows standing, sitting, and maintaining a stable body position while walking, running, and all other movements.

7. Fxn of Cardiac Muscle:
Pump blood

8. Pumping Blood
Cardiac muscle cells contract to provide all cells with blood
Blood has all of the nutrients that cells need to be healthy

9. transport nutrients & waste
Fxn of Smooth Muscle:
transport nutrients & waste

10. Transport Nutrients/Waste
Smooth muscles line the inside of hollow organs and blood vessels
Ex: swallowing, digesting food in intestines, defecating, erection
