1. Skeletal & Muscular System

2. Skeletal System

3. Function: The skeletal system ….
Holds the body up (structure and shape)
Protects internal organs
Helps the body move
Stores minerals, Calcium, Phosphorus
Makes blood cells

4. PARTS-BONES -make up the skeletal system
Made of living cells and protein fibers
- Produce blood cells in the bone marrow
bones in adult body
- 300 bones in infant (later fuse together)

5. PARTS-CARTILAGE - gives shape Connects the bones Supports the body
Softer and more flexible than bone

6. PARTS-LIGAMENTS holds bones together at the joins
Connects bone to bone
900 ligaments in human body

7. PARTS-JOINTS place where 2 or more bones connect together
Allow movement

9. PARTS-TENDONS tough connective tissue that connects bone to muscle

10. MUSCULAR SYSTEM

11. Function The muscular system… -helps you move
-helps move blood through the body (arteries/veins/capillaries)
-pumps your blood (heart)
-helps you breathe (lungs)
-moves food through digestive system (stomach, intestines)

13. TYPES OF MUSCLE SMOOTH MUSCLE
tissue in walls of organs, arteries, veins
In the stomach, lungs, and other soft internal organs
Involuntary movement (moves by itself)
Controls the way blood flows through circulatory system

14. TYPES OF MUSCLE SKELETAL OR STRAITED MUSCLE:
attached to legs, arms, back, and torso
Helps to move bones
Voluntary movement

15. TYPES OF MUSCLE CARDIAC MUSCLE: - only in the heart
involuntary movement (moves by itself)

17. CONNECTION TO OTHER SYSTEMS
Skeletal and muscular system work together to help you move
Muscular system works with circulatory system to pump blood through the body
Muscular system works with digestive system to move food through digestion
Muscular system works with respiratory system to exchange gases
Muscular system works with excretory system to eliminate waste
Nervous system controls skeletal and muscular system
