1. After today, you will be able to answer:
The Human Body
After today, you will be able to answer:
What are we made of?
How are we organized?

2. Study of the Human Body Called anatomy and physiology
Anatomy- study of the shape of an organism and its parts
Ex: What are the size and shape of our lungs?
Physiology – study of the function of an organism and its parts
Ex: What do our lungs do for our bodies?

3. Remember!
What are all living organisms made of?
Cells!!!!

4. Levels of organization
We are living organisms and are also made out of cells
LEVELS EXAMPLE
A group of cells make a tissue cardiac tissue

5. Levels of organization
We are living organisms and are also made out of cells
LEVELS EXAMPLE
A group of cells make a tissue cardiac tissue
A group of tissues make an organ heart

9. Organ Systems There are 11 main organ systems in the human body…
Which ones can you name?

10. Organ systems
Nervous
Skeletal
Muscular
Circulatory
Digestive
Respiratory
Integumentary (Skin)
Excretory (Waste)

12. Nervous system
Responsible for process information from the environment
Senses: taste, see, touch, etc.
Also to send messages from the brain to other organs
Controls movement and function
Ex: tells your lungs to inhale and keeps your heart beating
Made of special cells- neurons

13. Skeletal system Gives your body shape and structure
Protects internal organs
Ex: rib cage and heart
Attaches to muscular system – to help with movement
Made of bones, ligaments and tendons

14. Muscular System Provides movement Attached to skeletal system
Two types of muscles:
Voluntary
Ex: you kick your leg
Involuntary
Ex: your heart beating
Ex: Your stomach moving food

15. Circulatory System Moves blood through the body
Transports oxygen from lungs to other organs
Made of heart, arteries, capillaries and veins
Arteries- blood flows away from heart
Veins- blood flows to the heart

16. Digestive System Breaks down food to chemicals that our body can use
Starts with the mouth!
Ex: chewing and digesting
This provides energy for your body!
