Misc.
Diseases
100
How many lobes does each lung have?
Right = 3 Left = 2
100
Where does cellular respiration occur?
Mitochondria
100
Air enters the body where?
Mouth and/or nose
100

What body cavity can the lungs be found in?

thoracic

100

A chronic lung disease that causes inflammation and constriction of the airways

What is Asthma

200

What are the membranes that line the lungs?

The surface of each lung is covered by a serous membrane called the visceral pleura; the parietal pleura lines the thoracic cavity.

200
What is internal respiration?
transfer of oxygen from blood to the body cells and transfer of waste and carbon dioxide from body cells to blood
200

The amount of air that moves into and out of the lungs during normal quiet breathing

Tidal Volume

200
What are the organs of the upper respiratory tract?
Nose, nasal cavity, sinuses, pharynx
200

A group of diseases that restrict airflow and make breathing difficult. The main cause is smoking.

What is either chronic bronchitis or emphysema

300
Where does air go after it leaves the trachea (when inhaling)?
Primary Bronchi
300
What is external respiration?
Gas exchange between the air and blood
300
Where does the trachea lie in relation to the esophagus?
The trachea is ventral to the esophagus
300

What are the organs of the lower respiratory tract?

 trachea, bronchial tubes, lungs

300

A progressive, inherited disease that causes malfunction in cells that produce mucus and certain other body fluids

What is cystic fibrosis

400
What structure resembles a bunch of grapes?
Alveoli
400
The taking in of air is called what?
Inhalation
400

What happens to your respiration rate when Carbon dioxide levels increase?

It increases you breath faster

400
What is the function of the mucus membrane that lines the nasal cavities?
moisten and warm the air
400

Lung infection caused by bacteria, virus or fungus

Causes alveoli to fill with fluid or pus, making it difficult to breathe

What is pneumonia

500

What is the important substance that reduces surface tension in the alveoli, making it easier to change the surface area of the alveoli and breathe?

surfactant

500

Trace oxygen from entering the respiratory system to exiting the respiratory system as CO2

Nose/ Mouth ->nasal cavity-> pharynx-> larynx -> trachea-> bronchi-> bronchioles-> alveoli -> capilarries and into the bloodstream->hemoglobin in red blood cells ->transported throughout the body->cellular processes (like cellular respiration) 

carbon dioxide as a waste product of cellular reactions-> blood stream-> veins->alveloi -> bronchioles-> bronchi-> trachea-> out the mouth or nose



500

Air travels from the pharynx to the ________ to the _____ and finally to the ______ where oxygen is exchanged with the blood stream.

trachea, bronchi, alveoli

500
How does oxygen enter the blood stream?
diffuse across the respiratory membrane in the alveoli into the capillaries
500

Contagious infection of the lungs caused by bacteria 

In the 1900s was the leading cause of death in the U.S.

What is Tuberculosis
