Brings in oxygen to go into the cells, and picks up carbon dioxide to be removed from
the bodyguard
What are the 7 parts of the respiratory system?
1. Nose
2. Pharynx
3. Larynx (voice box)
4. Trachea (windpipe)
5. Bronchi
6. Bronchioles
7. Alveoli
What are alveoli surrounded by to allow the exchange of O2 and CO2?
Capillaries
What is cilia?
Tiny hairs in the nose and trachea that wave particles up away and out
What is mucus?
Something that keeps the air warm and moist but also traps particles
How many alveoli does each lung have?
150 million
What does hemoglobin do?
,Carries oxygen through the blood
What is pleura?
Sacs that surround the lungs
What is the diaphragm?
The muscle at the bottom of the thoracic cavity
What happens during inhalation?
Diaphragm moves down (contracts), rib cage rises, volume of chest cavity increases, air
moves in to fill the space
What happens during exhalation?
Diaphragm moves up (relaxes), rib cage lowers, space becomes smaller, air is pushed
out of lungs
What does the medulla oblongata do?
Controls breathing
What is chronic bronchitis?
Bronchi swell and become clogged with mucus
What is emphysema?
Tissues in lungs lose elasticity; tissues can't enough O2 or get rid of enough CO2
What is lung cancer?
Cells that do not stop reproducing; can spread to other locations because lungs are so
central and connected to so much; survival is generally less then 5 years from diagnosis
What is heart disease?
Blood vessels are constricted, blood pressure rises, heart has to work harder, heart
wears out more quickly
,What is cystic fibrosis?
Genetic (recessive); lungs can get clogged with mucous
What is mesothelioma?
Lungs become exposed to asbestos and lose elasticity
What is elastic recoil?
The ability for the alveoli to get filled with air then return to their normal shape once the
air is released
What is a spirometer?
an instrument for measuring the air capacity of the lungs
What is tidal volume?
The amount of air taken in and breathed out in a typical breath
What is supplemental volume?
The xtra air that can be inhaled or exhaled with a deep breath
What is reserve amount?
The amount of extra air you can breathe out when you force air out of your lungs
What is residual amount?
The amount of air in your lungs that you cannot get rid of (even during forced exhaling)
What is vital capacity?
All the air you can control going in or out of your lungs (supplemental + reserve = vital)
What is total capacity?
From the top of your supplemental amount to the bottom of your residual volume
Main idea

- It helps the reader understand your purpose for writing the paragraph or essay
Conclusion
A deduction made by the reader about an unstated outcome from reading passage
Inference
A conclusion one can draw from the presented details.
anatomical position
a standard position in which the body is facing forward, the feet are parallel to each
other, and the arms are at the sides with the palms facing forward
Cells
The basic unit of structure and function in all living things
