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? - ANSWER:
Capillaries
What is cilia? - ANSWER: Tiny hairs in the nose and trachea that wave particles up away
and out
What is mucus? - ANSWER: Something that keeps the air warm and moist but also traps
particles
What does hemoglobin do? - ANSWER: Carries oxygen through the blood
What is pleura? - ANSWER: Sacs that surround the lungs
What is the diaphragm? - ANSWER: The muscle at the bottom of the thoracic cavity
What happens during inhalation? - ANSWER: Diaphragm moves down (contracts), rib
cage rises, volume of chest cavity increases, air moves in to fill the space

,What happens during exhalation? - ANSWER: Diaphragm moves up (relaxes), rib cage
lowers, space becomes smaller, air is pushed out of lungs
What does the medulla oblongata do? - ANSWER: Controls breathing
What is chronic bronchitis? - ANSWER: Bronchi swell and become clogged with mucus
What is emphysema? - ANSWER: Tissues in lungs lose elasticity; tissues can't enough O2
or get rid of enough CO2
What is lung cancer? - ANSWER: 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 elastic recoil? - ANSWER: 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? - ANSWER: an instrument for measuring the air capacity of the
lungs
What is tidal volume? - ANSWER: The amount of air taken in and breathed out in a
typical breath
What is supplemental volume? - ANSWER: The xtra air that can be inhaled or exhaled
with a deep breath
What is reserve amount? - ANSWER: The amount of extra air you can breathe out when
you force air out of your lungs
What is residual amount? - ANSWER: The amount of air in your lungs that you cannot get
rid of (even during forced exhaling)
2|Page
,What is vital capacity? - ANSWER: All the air you can control going in or out of your
lungs (supplemental + reserve = vital)
What is total capacity? - ANSWER: From the top of your supplemental amount to the
bottom of your residual volume
Main idea - ANSWER: the most important or central thought of a paragraph or larger
section of text, which tells the reader what the text is about
Topic - ANSWER: a particular issue or idea that serves as the subject of a paragraph,
essay, report, or speech

the feet are parallel to each other, and the arms are at the sides with the palms facing forward
Cells - ANSWER: The basic unit of structure and function in all living things
3|Page
, Cellular functions - ANSWER: Processes that include growth, metabolism, replication,
protein synthesis, and movement
Directional terminology - ANSWER: Words used to explain relationships of locations of
anatomical elements (distal, posterior, medial, etc.)
organ system - ANSWER: A group of organs that work together in performing vital body
functions.
Organelle - ANSWER: specialized structure that performs important cellular functions
within a eukaryotic cell
Organ - ANSWER: A collection of tissues that carry out a specialized function of the body
Reference Planes - ANSWER: Planes dividing the body to describe locations
(ex: sagittal, coronal, and transverse)
Tissue - ANSWER: A group of similar cells that perform a specific function.
Eukaryotic cells - ANSWER: Contain a nucleus and other organelles that are bound by
membranes.
prokaryotic cell - ANSWER: cell that does not have a nucleus or other membrane-bound
organelles. (Bacteria)
Ribosome - ANSWER: site of protein synthesis
Nucleus - ANSWER: A part of the cell containing DNA and RNA and responsible for
growth and reproduction
Nucleolus - ANSWER: Found inside the nucleus and produces ribosomes
