Part 2 Flashcards
Alveoli are lined with super thin, wet membranes made up of what?
simple Squamous epithelium tissue
With lung diffusion what is being exchanged into the blood and what is being put into the lungs to exhale?
Oxygen is being diffused into the blood exchanged for Carbon dioxide (CO2) to be exhaled out the lungs
What are the two principals that make respiration possible?
Diffusion and Bulk flow
- Sweating, quick shallow breaths, shortness of breath, light headedness is all signs of?
Hyperventilating
With hyperventilation how is CO2 and oxygen being effected
You are exhaling more then you should (your body is not getting enough CO2/having too much oxygen.
The drop in CO2 when you hyperventilate is called?
Hypocapnia
Hemoglobin contain 4 protein chains and each one contains what kind of atom?
An iron atom which easily binds with oxygen
What principal tells your body to want to bind more oxygen to hemoglobin or to let it go?
Partial Pressure
Molecules diffuse from ____concentration to______ concentration?
High concentration to low concentration
Air is a mixture of what molecules
Nitrogen, oxygen, and other
What percent of air is oxygen
21%
The total pressure exerted by a mixture of gasses is the sum of the pressures exerted by each gas in the mixture is what law
Daltons Law
Partial pressure tells us what?
How much oxygen there is based o the pressure it’s creating
The pressure of air at sea level is
760 mmHg
The partial pressure of air at sea level is
160 mmHg (21% of 760mmHg = partial pressure of air at sea level)
