Anatomy Flashcards
1
Q
Exchange of gases between a living organism and its environment
A
Respiration
2
Q
Major Functions of Respiratory System
A
- Provides passageway for O2 to enter body
- Provides passageway for CO2 to exit body
- Facilitate gas exchange of O2 + CO2 in body
3
Q
Mechanical process of moving air in and out of lungs
A
Ventilation
4
Q
Movement of molecules through a membrane from an area of greater concentration to and area of lesser concentration
A
Diffusion
5
Q
Circulation of blood through the capillaries
A
Perfusion
6
Q
Responsible for warming and humidifying incoming air
A
Upper Airway
7
Q
Area where respiratory exchange of O2 and CO2 occurs
A
Lower Airway
8
Q
Involved in Conduction of air
A
- Nose
- Pharynx
- Larynx
- Trachea
- Bronchi
- Terminal Bronchioles
9
Q
Where does diffusion happen?
A
Alveoli
10
Q
Involved in gas exchange
A
- Respiratory Bronchioles
- Alveolar ducts
- Alveoli
11
Q
- Air and food passage way
- Epithelium lining changes to stratified squamous epithelium to accommodate food passage (chemical and friction)
- Contains palatine and lingual tonsils
A
Oropharynx
12
Q
- Two-way streets filled with mucus producing (goblet) cells
- Small openings connect to nasal cavity
- Air moves in nasal cavity and mucous drains into the cavity
- Also help warm and humidify air
- Enhances the voice resonance
A
Paranasal Sinuses
13
Q
Epiglottis
A
- Leaf shaped structure attached to the thyroid cartilage by the “stem”
- moves up and down to close opening to the glottis
- Keeps food out of the lungs
14
Q
Where the bronchus divides into branches
A
Carina
