Respiratory System Flashcards
4 parts of the Respiration Process
- Pulmonary Process
- Pulmonary Diffusion
- Transport
- Cellular Respiration
Organs involved in the upper respiratory tract
nose nasal cavity sinuses nasopharynx oropharnyx larngopharynx
organs involved in the lower respiratory tract
larynx trachea bronchial tree lungs alveoli
what is the first filtering technique
goblet cells
Tidal volume
normal volume in lungs at rest
inspiratory reserve volume
maximal inspiration, how much above tidal volume you can get
expiratory reserve volume
how much air you can force out
residual volume
amount of oxygen left in lungs after expiratory reserve
-cant ever get all the air out
total lung capacity
all of the categories combine
vital capacity
combination of max inspiration and expiration
Pulmonary respiration
gets air from the outside environment into the lungs
pulmonary diffusion
2 functions: replenishes O2 and removes CO2
Partial pressure
gas exchange
daltons law
total pressure of air
760 mmHg
pressure of O2
159mmHg
Transport
oxyhemoglobin
-98% of oxygen is attached on hemoglobin
-2% dissolved in plasma
deoxyhemoglobin
CO2 transport
- 10% dissolved in plasma
- 70% transported in the form of bicarbonate
- 20% bound to globin portion of hemoglobin
