Stefan Flashcards
What are the primary functions of the respirating system?
Exchange of gases between the atmosphere and blood.
Homeostatic regulation of pH.
Metabolic functions.
Vocalisation.
What is the function of the conducting zone?
Brings air into and out of the lungs - before the air reaches the lungs it get humidified, warmed, and filtered.
What is the function of the respiratory zone?
Gas exchange.
What are the requirements for ventilation?
Pump.
Hollow conducting system.
Air flow.
Pressure difference.
What is ventilation?
Movement of air between the lungs and atmosphere.
What is the process of bulk flow?
Entire gas mixture not only a selected gas.
What is boyle’s law?
Pressure is inversely proportional to volume.
What is tidal volume?
Volume of air that flows into lungs during inspiration.
What is the minute volume?
Total volume of air that enters or exits the respiratory system.
What is inspiratory capacity?
All air can be inspired from resting position.
What is functional residual capacity?
Volume of air remaining in lungs after normal expiration.
What is vital capacity?
All air that you are capable of moving.
What is total lung capacity?
All air the lungs after maximal inspiration.
What is the driving force for diffusion?
Partial pressure difference.
What are two types of concept maps?
Systemic.
Physiological.
What kind of approach is the ‘why’?
Teleological approach.
What kind of approach is the ‘how’?
Mechanistic approach.
What is inter generational level?
Transfer of DNA from one generation to the other.
What is the organismal level?
Flow of information within the body.
What is homeostasis.
Regulation of body’s internal environment.
What are some environmental factors that affects cells?
Osmolarity, temperature and pH.
What are material that the cell needs?
Nutrients, water, sodium and calcium.
What is the law of mass balance?
Any gain must be offset by an equal loss.
What is redundancy ?
When the body has a safety margin - two kidneys.
What is adaptability?
The body adapts to a new normal.
