2. objectives
Students will identify and/or describe the general functions of the major systems (respiratory system) of the human body.
Students will identify and/or describe how the major systems of the human body interact to maintain homeostasis.

3. Essential question
How does the circulatory and respiratory systems work together to allow the body to maintain homeostasis?

4. Vocabulary
Lungs: each of the pair of organs situated within the rib cage, consisting of elastic sacs with branching passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed
Respiratory System: is the group of organs that takes in oxygen and get rid of carbon dioxide

5. Materials moving around the body
Respiration (breathing) is the transportation of oxygen from the environment to tissues and cells and the transportation of carbon dioxide and wastes away from the cells and into the environment
Oxygen moves into the blood from the lungs when you inhale
The oxygen is taken to the cells to help with cellular respiration
The body moves carbon dioxide, a waste product of cellular respiration, from the body cells, into capillaries, carried through the blood to the lungs where it Is freed back into the environment

6. Parts of the respiratory system

7. The Nose, Pharynx, Larynx, and trachea
Air enters your body through your nose and mouth
From your nose it travels into the pharynx (throat)
The pharynx branches into two tubes the esophagus, which leads to the stomach, and the larynx which leads to the lungs
The trachea, or wind pipe, splits into two branches called bronchi and each one connects to a lung

8. Bronchioles, Alveoli and diaphragm
Inside the lungs, bronchioles lead to sacs called alveoli
When you inhale, the diaphragm contracts and allows you to suck in air
When you exhale, the diaphragm relaxes and it allows the it to by let out
So, as you breathe, the air is sucked in and forced through the thin walls of the alveoli and forced into the blood vessels surrounding them

9. Diseases in the Respiratory system
Asthma:
When it the amount of air is reduced because of the inflammation of the bronchi
Pneumonia:
Inflammation of the lungs that could cause you to suffocate
Emphysema:
When the alveoli have been damaged and you can’t get the right amount of oxygen to the blood properly

10. Maintaining Homeostasis
The circulatory and respiratory systems work together to maintain homeostasis when the lungs transport the oxygen to the blood and the heart pups the blood to the body cells use I to survive.
They work together when the carbon dioxide is moved to the blood and it is brought back to the lungs where it is moved back into the air

11. How do materials move through the body?
High order question
How do materials move through the body?

12. Review/quiz What is the MAIN function of the Respiratory system?
Label the Chart with the Correct Organs (6 and 9 are the same thing)
What is the MAIN function of the Respiratory system?
Keep the body healthy
Take in oxygen and release carbon dioxide
Help the body move
