Upper Respiratory System
These are hollow areas in your head. They make your head lighters and they continue the warming, moisturizing and filtering processes.
Sinus cavities
What is the name of the large muscle that pulls air into the lungs?
The diaphragm
This is the amount of air exchanged by the lungs at rest
Tidal Volume
What is the sticky coating that is secreted by cells along your respiratory tract?
Mucus
What is meant by gas exchange and where does it happen?
Gas exchange is the exchange of oxygen and carbon dioxide; occurs in the lungs and across the respiratory membrane
These are bony plates inside your nasal passages. They are covered with mucus and cause the air to "bounce" around rather than flowing straight into your body.
Conchae
How is the left lung different from the right lung? (2 ways)
The left lung has 2 lobes instead of 3 and has a cardiac notch
The amount of air remaining in lungs after a forced exhalating
Residual volume
Name three things that nose hairs do.
1. Clean the air going in
2. Warm the air going in
3. Moisten the air going in
What is external respiration?
Exchanging carbon dioxide and oxygen with the environment through the lungs
Why are the cartilaginous rings that surround the trachea U shaped?
To allow room for the esophagus
What is the large tube that connect the larynx to the bronchi?
The trachea
The amount of air someone can consciously exchange with the environment (inhaling and exhaling)
Vital capacity
What are the tiny hairs that move back and forth along the trachea called?
Cilia
WHat is internal respiration?
Exchanging carbon dioxide and oxygen with all the tissues of the body
The part of the pharynx located behind your nasal cavity is called...
Nasopharynx
What are the two tubes that lead from the bottom of the trachea to each lung?
The bronchi
The additional amount of air that can be inhaled consciously
Inspiratory reserve volume
This happens when something irritates your nose
Sneeze
How does oxygen get from the alveoli into the capillaries? How does carbon dioxide get from the capillaries into the alveoli so it can be breathed out?
DIFFUSION
The part of the pharynx located behind your voice box
The laryngopharynx
What are the smaller tubes that branch off each bronchi within the lungs?
Bronchioles
The additional amount of air that can be exhaled consciously
Expiratory reserve volume
This happens when something irritates your throat or airways
Cough
What structures does oxygen pass through as it enters the body until it's final destination?
nasal cavity, pharynx, larynx, trachea, bronchus, bronchiole, alvelous
The reason boys voices deepen as they age
Their vocal cords grow longer
What are the tiny balloon-like sacs where carbon dioxide in the blood is exchanged for oxygen?
Alveoli
What is total lung volume equal to?
vital capacity + residual volume
To trap and remove foreign pathogens entering the throat
What makes up the "respiratory zone"?
Alveoli and associated capillaries that surround them
The largest cartilaginous portion of the larynx; also known as the Adam's apple
What surrounds the alveoli and enable the exchange of gases?
Capillaries
What is total lung volume in a typical adult male and female?
About 6 liters for adult men, 10% less for adult females
Adenoids
Why does our body need to breath in O2?
So our cells can perform cellular respiration - the process in which our body extracts a usuable source of energy from our food
