What is located behind the nose?
Nasopharynx
The Serous Membrane covering the surface of the lungs is called...
Visceral pleura
The flap of elastic cartilage that stops food from entering the larynx when swallowing is...
epiglottis
The cilia in the trachea move mucus towards the
throat
The opening between the vocal cords is called the
glottis
Which of the following is an area of diffusion of oxygen into the blood
aveolar sacs
What type of tissue makes up the walls of the aveoli?
simple squamous epithelium
The left lung has 2 lobes
true
The right lung has three lobes
true
The amount of air above the tidal volume that can be taken in forcilbly
Inspiratory reserve volume
The lipid molecule that coats aveoliar surfaces so they do not stick together is called
surfactant
Hypoventiliation increases carbonic acid in the blood and involves
really slow breathing
Conduction passageways include all EXCEPT:
nose, larynx, pharynx, alveoli
alveoli
Air moving in and out of the lungs is called
pulmonary ventilation
The gas exchange between blood and tissues is called
internal respiration
What is the superior part of the pharynx called?
nasopharynx
During inhalation, increased lung volume causes the pressure in the lungs to decrease
true
Oxygen binds with hemoglobin in the blood to form
oxyhemoglobin
T/F: inhaling, decrease of gas pressure produces a partial vacuum that forcibly sucks air in
true
T/F: during inhalation, air will move into the lungs until intrapulmonary pressure= atmo pressure
true
The exchange of oxygen and carbon dioxide occurs because of
simple diffusion
When exhaling, the diaphragm
relaxes
An emotionally-induced response where air movement is similar to crying
laughing
A very deep inhalation that ventilates all the aveoli is
yawning
Lymphatic organs found at the base of the tongue are called
tonsils
The respiratory volume of normal breathing
tidal volume
After leaving the trachea, air next goes to
main (primary) bronchi
T/F: to inspire, the diaphragm contracts to increase the size of the thoracic cavity
true
Carbon dioxide is transported in the blood as
bicarbonate ion
Is what is left in the lungs and cannot be voluntarily removed
residual volume
the amount of air exchanged during normal breathing
500 ml
The bluish cast of skin as a result of low oxygen is called
cyanosis
cessation of breathing is called
apnea
Does more CO2 in the blood increase or decrease blood pH?
decrease
The most important chemical stimulus that increases rate and depth of breathing is
increased CO2 in the blood
If you remove the larynx, a person would be unable to
speak
T/F: Inhaling, external intercostal muscles relax to increase the size of the thoracic cavity
false
Normal respiratory rate in adults is
12-18 rpm
The center of the respiratory control in the brain is
pons and medulla
Disease caused by decreased alveoli, inflamed bronchi, enlarged heart, difficulty breathing
emphysema
Caused by ascending too quickly from deep in the ocean
decompression sickness (the bends)
The majority of the air that we breath is this gas
Nitrogen
Warms and moistens the air that we breathe
nasal cavity
Order of structures in which oxygen passes
pharynx, larynx, trachea, bronchus
Runny nose, coughing, fever, joint aches, stomach upset
flu (influenza)
Common passageway for food and air
