Term
5 Functions of the Respiratory System
Definition
1. Provide area for gas exchange between air and blood.
2. Move air to and from exchange surfaces.
3. Protect respiratory surfaces from enviornmental variables and invasion by pathogens.
4. Permit vocal communication
5. Provide olfactory sensation to the CNS.
Term
Boyle's Law
Definition
As volume decreases, pressure increases, and as volume increases, pressure decreases.
Term
Serous membranes that protect the lungs
Definition
The visceral and parietal pleura
Term
Regions of the brain that control the repiratory system
Definition
Pons and Medulla oblongata
Term
Functions of the nasal cavity (3)
Definition
Warm, moisten, and filter
Term
What prevents foreign material from reaching the alveoli?
Definition
Cilia and mucus
Term
Factors that influence hemoglobin saturation
Definition
1. The PO2 of blood - high partial pressure allows more gas molecules to move.
2. The Blood pH - increases in hydrogen ion concentration (acidic) weakens the strength of the hemoglobin-oxygen bond.
3. Temperature of blood - Increased temperature less oxygen binds and unloading of oxygen from hemoglobin increases.
4. Metabloic activity within RBCs - involved in glycosis, generates a compound caled 2, 3 bisphosphoglycerate or BPG, which causes more oxygen to be released.
Term
Physical factors that influence ventilation
Definition
1. Respiratory resistance- friction/drag in air passageway
2. Lung compliance- expandalibity of the lungs.
3. Lung elasticity- ability of lungs to recoil.
4. Alveolar surface tension- liquid reduces surface tension
(Surfactant- reduces tension, allowing alveoli to fill with air)
Term
How is most CO2 carried to the lungs?
Definition
as a bicarbonate ion in the plasma
Term
Residual volume
Definition
The air remaining in the lungs
Term
Expiratory reserve volume
Definition
air forced out beyond tidal volume
Term
Inspiratory reserve volume
Definition
air forced in beyond tidal volume
Term
Inspiration
Definition
breathing in
Term
expiration
Definition
breathing out
Term
Internal respiration
Definition
Gas exchange between blood and body tissue cells
Term
External respitation
Definition
gas exchange between alveoli and blood
Term
Cellular respiration
Definition
oxygen absorbed into cells and is used to produce ATP
Term
Eupnea
Definition
breathing
Term
apnea
Definition
not breathing
Term
Tidal volume
Definition
noral amount of air taken in in each breath
Term
Vital capacity
Definition
total volume of exchangeable air
Term
6 nonrespiratory air movements
Definition
coughing, sneezing, laughing, crying, hiccuping, yawning.
Term
Muscles involved in respiration
Definition
diaphragm and intercostal rib muscles
Term
structural differences between right and left lungs
Definition
Left lung has one less lobe (where heart is)
