Lung Capacity
Functions
Path of Air
Inhalation/Exhalation
Gas exchange
100
The mechanical process of moving air into and out of the lungs; also called ventilation or inhalation and exhalation
What is breathing?
100
Hair in the nose filters out the particles in the air. Mucus traps particles not caught by the nose hairs. The mucous membrane also helps to warm and moisten the air.
What is modifying air?
100
Connects the nasal passages to the trachea.
What is the pharynx?
100
During inhalation, this moves down.
What is the diaphragm?
100
These are tiny sacs at the ends of the bronchioles in the lungs
What are alveoli?
200
The amount of air that remains in the lungs after a person exhales as forcefully as he or she can.
What is residual volume?
200
Sound starts when air is pushed up from the lungs through the larynx. When the muscles of the larynx relax or contract, they make the vocal cords get longer or shorter. The more tension on the cords, the higher the pitch of the sound. The more air that passes the larynx the more sound that is produced.
What is making speech/sound?
200
Directs air to the trachea and food to the esophagus.
What is the epiglottis?
200
How the intercostal (rib muscles) moves during exhalation.
What is down and in?
200
The process by which gasses are passed into and out of the blood stream.
What is diffusion?
300
The total amount of air that a person can exhale after taking as deep a breath as possible.
What is vital capacity?
300
The epiglottis directs air to the trachea and food to the esophagus. The trachea directs air to the bronchi. The bronchi send air to the bronchioles. The bronchioles deliver air to the alveoli.
What is transporting air?
300
The trachea directs air here.
What are the bronchi. (bronchus)
300
Volume increase, pressure decreases.
What is inhalation?
300
The gas that is passed from the alveoli into the blood stream.
What is oxygen?
400
The amount of air the lungs can hold after taking as deep a breath as possible (the sum of vital capacity and residual volume).
What is is total lung capacity?
400
Alveoli are covered by tiny blood vessels called capillaries. Oxygen molecules travel through the walls of the alveoli into a capillary and attach to red blood cells. The oxygen is used by the cells and carbon dioxide is returned to the lungs by the capillaries. The carbon dioxide leaves the capillaries and returns to the alveoli.
What is gas exchange?
400
Bronchi send air here.
What are the bronchioles?
400
Volume decreases, pressure increases
What is exhalation?
400
The gas that is passed from the blood stream back into the alveoli.
What is carbon dioxide?
500
Asthma , Emphysema, SARS
What are Respiratory Diseases?
500
During inhalation: - the diaphragm moves downward. - the intercostal muscles make the ribs move upward and outward. the volume of the chest cavity increases, pressure decreases and air rushes in. During exhalation: - the diaphragm moves upward. - the intercostal muscles make the ribs move downward and inward. - the volume of the chest cavity decreases and pressure increases and air rushes out.
What is changing lung pressure?
500
Bronchioles deliver air here.
What are the alveoli?
500
When the diaphragm and intercostal rib muscles get out of sync.
What are hiccups?
500
The process by which nutrients and oxygen are converted into energy and carbon dioxide.
What is cellular respiration?
