1. Skeletal & Muscular System

2. 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

3. PART 1: 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)

4. PART 2: CARTILAGE - Softer and more flexible than bone - gives shape
Connects the bones
Supports the body

5. Do Now! What are 3 things you learned from the muscle lab?
EXPLAIN how proof (DATA) from a lab station led you to learn this?

6. PART 3: LIGAMENTS Connects bone to bone
holds bones together at the joints
900 ligaments in human body

7. PART 4: JOINTS
where 2 or more bones connect together
Allow movement

8. PART 5: TENDONS
tough connective tissue that
connects bone to muscle

9. MUSCULAR SYSTEM

10. Muscular System 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)

12. 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

13. TYPES OF MUSCLE Skeletal or Striated Muscle:
attached to legs, arms, back, and torso
Helps to move bones
Voluntary movement

14. TYPES OF MUSCLE Cardiac Muscle: - only in the heart
involuntary movement (moves by itself)

16. CONNECTION TO THE 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
