Mod 7: Respiratory System Flashcards
1
Q
Nas/o= nose
A
- Exchanges air during inhaling and exhaling
- warms, moisturizes and filters inhaled air
2
Q
Sinus/o
Sinuses
A
- produces mucus for nasal cavities
- makes bones of skull lighter
- aid in sound production
3
Q
Pharynx = pharyng/o
A
Transports air back and forth between the nose and the trachea
4
Q
Larynx = laryng/o
A
Makes speech possible
- known as voice box
5
Q
Epiglottis= epiglott/o
A
Closes off the trachea during swallowing
6
Q
Trachea= trache/o
A
- transports air back and forth between pharynx and bronchi
7
Q
Bronchi = bronch/o, bronchi/o
A
Transports air from the trachea into the lungs
8
Q
Alveoli= alveol/o
A
- air sacs that exchange gases with the pulmonary capillary blood
9
Q
Lungs= pneum/o
Pneumon/o
Pulmon/o
A
- bring oxygen into the body
- remove carbon dioxide
- remove some water waste from the body
10
Q
Mediastinum
A
- middle section of chest cavity
- located between lungs
- contains connective tissue and organs
11
Q
Pleura
A
- thin moist slippery membrane that covers outer surface of lungs
- and lines inner surface of thoracic cavity
- Parietal pleura
- outer layer of Pleura
- lines walls of thoracic cavity
- covers diaphragm
- forms the sac containing each lung
- is attached to chest wall
- parietal means ‘ relating to walls of a cavity ‘ - Visceral pleura
- inner layer of pleura
- attaches directly to lungs
- visceral means ‘relating to internal organs’ - Pleural cavity
- known as pleural space
- thin fluid filled space between parietal and visceral pleura membranes
- fluid acts as lubricant
- this allows membranes to slide over easily during respiration
12
Q
Diaphragm
A
- known as thoracic diaphragm
- dome shaped sheet f muscle
- separates thoracic cavity from abdomen
- contraction and relaxation of this muscle makes breathing possible
Phrenic nerves
- stimulates diaphragm and causes it to contract
