Respiratory System Flashcards
Organs of the respiratory system
nose Pharynx (throat) Larynx (voice box) Trachea (windpipe) Bronchus (bronchi) Lungs Diaphragm Mediastinum
Function of the respiratory system
respiration or to breath and exchange of O2 and CO2
How respiration works
inhale O2, that is then taken into the lungs
O2 passes from lungs into capillaries then blood
CO2 passes from blood into lungs
NOSE
- warms the air that enters
- lined with mucous membrane and fine hairs to filter particles
- divided into 2 parts: nasal and septum
Pharynx
- moves food, and air into correct passages
- AIR: Air - nose/mouth - pharynx - larynx - trachea - bronchi - lungs
- FOOD: Food - mouth - pharynx - esophagus - stomach
- Mastication : chewing aspiration: food goes into lungs
- Pharynx: Adenoids which are lymphoid tissue behind nasal cavity; and tonsils which are lymphoid tissue located behind the mouth
Lungs
- Thoracic cavity covered in pleura (membranous lining)
- lungs separated by space called mediastinum ( consists of heart, esophagus, trachea, etc.) below the lungs is the diaphragm
- lungs divided into lobes, left lung: 2 lobes right lung: 3 lobes
- AIR: nose/mouth - Pharynx - Larynx - Trachea - Bronchi - Bronchioles - Alveoli
- Alveoli exchange oxygen and carbon dioxide
