Schiller Study Guide Respiratory System

Front 1

Breathing

Back 1

The mechanical movement of air into and out of your lungs

Front 2

External Respiration

Back 2

The exchange of gases between the atmosphere and the blood, which occurs in the lungs

Front 3

Internal Respiration

Back 3

The exchange of gases between the blood and the body's cells

Front 4

Trachea

Back 4

The epiglottis allows air to pass from the larynx in a long tube in the chest cavity called the Trachea, or wind pipe.

Front 5

Pharynx

Back 5

This is where filtered air passes through, located in the upper throat

Front 6

Larynx

Back 6

-commonly known as the voice box
-functions as an airway to lungs
-provides us with a way of communicating

Front 7

Epiglottis

Back 7

-A flap of tissue that covers the larynx
-prevents food particles from entering the respiratory tubes

Front 8

Cilia

Back 8

-Hairlike structures that filter dust and other particles from the airways.
-they line the nasal passageways as well as other respiratory areas

Front 9

Bronchi

Back 9

The two larger tubes that branch out of the trachea and lead to the lungs

Front 10

Bronchiole

Back 10

The bronchi break into even smaller tubes called the bronchiole

Front 11

Alveolus

Back 11

The bronchioles travels to a smaller passageway with air sacs called the alveolus.
-only one cell thick
-surrounded by thin capillaries

Front 12

Lungs

Back 12

-largest organs in the respiratory system
-where gas exchange takes place

Front 13

Diaphragm

Back 13

-seperates the heart, lungs, and ribs from abdomin
-contacts rhythmically to the way you breath
(inhale: tighten, exhale: loose) It does this to increase space in your chest cavity

Front 14

ATP

Back 14

-adenosine triphosphate
-"energy currency of life"
-High energy molecule that stores the energy we need to do things.

Front 15

Asthma

Back 15

Respiratory pathways become irritated and bronchioles constrict

Front 16

Bronchitis

Back 16

Respiratory pathways become infected, resulting in coughing and production of mucus

Front 17

Emphysema

Back 17

Alveoli break down, resulting in reduced surface area needed for gas exchange with alveoli's blood capillaries

Front 18

Pneumonia

Back 18

Infection of the lungs that causes the alveoli to collect mucus (>_<) material

Front 19

Pulmonary Tuberculosis

Back 19

A specific bacterium infects the lungs, resulting in less elasticity of the blood capillaries surrouding the alveoli , thus decreasing effective gas exchange between the air and blood

Front 20

Lung Cancer

Back 20

Uncontrolled cell growth in lung tissue can lead to a persistent cough, shortness of breath, bronchitis, or pneumonia, and can lead to death. :O
