Part A

RESPIRATORY SYSTEM To bring oxygen into your body, and remove the carbon dioxide from your body, we use the respiratory system. Your body needs oxygen to survive.

Part A

5 FUN FACTS The right lung is slightly larger than the left. The breathing rate is faster in children. Sneezes travel at about 100 miles per hour. Your workout will often make you sneeze. Children breathing only through the mouth

have an increased risk at developing a lisp.

Part A

MAJOR ORGANSLungs- oxygen is taken in, and carbon dioxide is breathed out through respirationTrachea- Also known as the windpipe, the trachea filters the air we breatheBronchi- Air tubes that carry air to the lungsDiaphragm- It contacts when breathing. It’s a muscle located under the lungs, and enlarges the space the lungs are in

Part B

FUN FACTWhy Do People Yawn?When someone’s sleepy, they don’t get enough oxygen when breathing. In response, the brain makes a person take a long and deep breath; a yawn.

Part B

Circulatory System: The Respiratory System is necessary during this other body system because the blood carries oxygen around the body which is received by the lungs during respiration.

Part B

PATHWAY1. Oxygen enters the nostrils2. It goes through the trachea3. Into the left & right bronchi4. Re-branches into the bronchioles 5. Lungs inflate with the compression of the

diaphragm 6. Diaphragm pushes air and lungs deflate,

and CO2 exits the mouth or nostrils

Part C

BRONCHITIS Bronchitis is the inflammation of the

bronchial tubes, or the pathway that carries oxygen. Symptoms include wheezing, coughing, and shortness of breath. Often times, smoking is the cause of severe bronchitis.

Part C

FACTHow asthma works:Asthma is a chronic disease that affects the lung’s airways. The band of muscle around them tightens, reducing the breath. In asthma patients, this is caused sometimes by irritants, (ex. Smoke) heavy breathing (often from exercise), or cold weather. Rescue inhalers make it easier to breathe, but inhaled steroids are often a daily medication.

Part C

SLIDE #14 A common disease that effects the

respiratory system, is Lung Cancer. Lung Cancer can occur in one or both lungs Cancer affects the lung cells so that the cells

cannot function properly, which is to carry oxygen to blood.

Part D

SLIDE #15 The Respiratory system helps the Circulatory

system by moving oxygen throughout the body so cells can do work

It also helps the Circulatory remove waste (like CO2)

Part D

SLIDE #16The average adult with clean lungs can hold his/her breath for a minute and 30 seconds.

The longest world record for breath holding is held by Stig Severinsen. He held his breath underwater for 20 minutes and 00 seconds.

Part D

SLIDE #17 What is another name for the windpipe? a) Lungs b) Larynx c) Trachea d) Esophagus What important activity takes place in the

lungs? a) Food is digested b) Liquid waste is exchanged for carbon dioxide c) The trachea is exchanged for the larynx d) Oxygen is exchanged for carbon dioxide

Part D

SLIDE #18 To go on living, the body’s cells need food,

water, chemicals, and… a) helium b) Oxygen c) vegetables d)carbon dioxide What is Cancer? Explain in a sentence or two.
