Front 2

Alveoli

Back 2

The lungs are made up of millions of ________ wich are located at the end of the bronchioles. They have lots of capillaries where the exchange of oxygen and carbon dioxide takes place.

Front 3

Ribs

Back 3

Muscles that are located between the________ contract and relax helping move air in and out of the lungs.

Front 4

Cellular Respiration

Back 4

In cell, when sugar and oxygen combine to produce energy, carbon dioxide and water are also produced. this reaction is called__________.

Front 5

Tars

Back 5

_______ are sticky brown substances that are found in cigarettes. They collect in smokers lungs, irritate cells, and prevent oxygen and carbon dioxide from being exchanged.

Front 6

Nicotine

Back 6

The addictive chemicle found in tobacco is called_______. It affects the nervouse system and smokers crave the feeling they get when they smoke cigarettes.

Front 7

Carbon Monoxide

Back 7

_______is a poisonouse gas in cigarette smoke. It attaches to hemoglobin and then oxygen cannot be carried by red blood cells. The chemicle symbol is CO.

Front 8

Emphyema

Back 8

______can occur when the alveoli are damaged by smoke. Breathing becomes difficult as a result.

Front 9

Sulfur Dioxide

Back 9

______is a gas found in polluted air. It irratates the eyes, nose, throat, and damages the lungs. The chemicle symbol is SO.2

Front 10

Nitrogen Dioxide

Back 10

______is a gas found in polluted air that irratates the eyes, and nose, and can cause bronchitis and pneumonia

Front 11

Chemicle Reaction For Cellular Respiration

Back 11

Sugar + oxygen ----> energy + carbon dioxide + water is the ______

Front 12

Pollution

Back 12

Air that is "dirty" enough to cause health issues is reffered to as air ______

Front 13

Larynx

Back 13

The______is a firm structure at the top of your trachea. It is called the voice box or you adams apple, and contains the voval cords. When air passes through the vocal cords, they vibrate, making sounds that produce speech

Front 14

Respiratory System

Back 14

The major parts of the______are the nose, mouth, trachea, and lungs. These parts and others help deliver oxygen and other gasses to the blood stream and remove CO. and other waste products from the blood.

Front 15

Epiglottis

Back 15

The______ is a flap of tissue that covers the opening to the trachea when you swallow. It's function is to keep food from entering the trachea.

Front 16

Bronchi

Back 16

The bottom of the trachea splits into two branches called______. Each one goes to a lung and delivers air to it.

Front 17

Mucous Membrane

Back 17

The nose is lined with a______. It moistens the air to prevent lung tissue from drying out

Front 18

Pneumonia

Back 18

______ is caused by an infection in the lungs. It can be caused by microbes like bacteria and viruses, or by irritations from particles or gasses. The symptoms may be a painful cough and fever. The primary result is a buildup of fluids in one or both lungs

Front 19

Trachea

Back 19

The______ starts at the top of your throat and is in front of the esophagus. It connects to the lungs with your pharynx and allows air to enter your lungs.

Front 20

Cillia

Back 20

The trachea and bronchi are lined with verry fine hair-like structures called______. They wave back and fourth moving mucous, along with dust and other particles up and out of the respiratory system

Front 21

Bronchiole

Back 21

Each bronchus (singluar of bronchi) branches into several smaller and smaller tubes calles______ that are connected to the alveoli.

Front 22

Pharynx

Back 22

Your nasal cavity and you mouth join at the back of your throat at the______

Front 23

Ozone

Back 23

When nitrogen oxides are exposed to sunlight, molecules of O.3______ are formed. The levels are highest in the daytime and cause lung and eye irratation, and damages plants and manufactured materials such as rubber.

Front 24

Air

Back 24

______ is about 79% nitrogen, 20% oxygen, and 1% other gasses.

Front 25

Solid Suspended Particles

Back 25

The dust, smoke, soot, ash, and pollen are in the air, they are reffered to as______

Front 26

AQI (Air Quality Index)

Back 26

The ______ is an index used to report daily air quality for five major are pollutants: ground level ozone, particle pollution (also known as particle matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. It ranges from 0-500. The higher the AQI value, the more polluted the air. Valused above 100 are considered to be unhealthy - at first for certain sensitive groups of people, then for everyone as the values get higher.

Front 27

Diaphragm

Back 27

The ______ is a large flat muscle located at the bottom of the ribcage. It separates the ribcage from the abdomen. During inhalation, the diaphragm contracts, wich increases the volume of the chest and air will rush into the lungs. During exhalation, the diaphragm relaxes and pushes on the lungs, wich forces the air out.
