BIO 669 QUIZ 5 EXAM QUESTIONS AND CORRECT
ANSWERS – LATEST 2024/2025
What Happens When The Lungs Lose Elasticity? - Ans ✓Compliance Goes Up
And Allows For Easier Expansion, But Leads To Reduced Recoil Into A Smaller
Space
(Increasing Chest Space And Air Way Volume)
Where Is Airway Resistance The Highest? - Ans ✓In Nasal Passages
What Has The Second Highest Airway Resistance? - Ans ✓Pharynx
What Occurs To The Body With Widespread Acidemia Or Widespread
Insufficiency? - Ans ✓Increased Bronchi Constriction= More Difficult To Breath
And Need To Increase Respiratory Effort
Ie. Copd Patient Gasping For Air And Fighting Harder To Breath.
What Are The 4 Steps Of Ventilation Of The Lungs? - Ans ✓1. Ventilation Of Air
In And Out Of Lungs

2. Diffusion Of Oxygen From Alveoli Out Into The Capillary Blood
3. Perfusion Of Systemic Capillaries With O2 Blood
4. Diffusion Of O2 From Systemic Capillaries Into The Cell.
What Is Barometric Pressure? - Ans ✓Measure Of Pressure Of All The Mixture Of
Gases On A Given Chamber (Aside From Water Pressure)
What Do You Have More Of, Perfusion Of Ventilation? - Ans ✓Perfusion
How Is Saturation Determined? - Ans ✓The Average Of O2 That Is Binded To The
Over All Hemoglobin
What Happens To Saturation When Pressure Rises? - Ans ✓It Rises.
What Are Examples Of Interactions That Decrease The Affinity In The Binding
Of O2 To Hemoglobin? - Ans ✓Increased H+ Ion, Drop In Ph, High Co2, Increased
Temp, 23 Dpg
Where Is 23 Dpg Made? - Ans ✓The Liver
What Is A Right Shift? - Ans ✓The Offloading Of Hemoglobin In The Decrease In
Affinity For O2

BIO
Why Does Hemoglobins Affinity Increase At The Area Of The Lungs? - Ans
✓There Is A Lower Temperature, Rise Of Ph That Is Relative To The Systemic
Circuit, And A Low Level In Carbon Dioxide (Due To Alveolar Diffusing Co2
What Happens When You Go Up To A Higher Altitude? - Ans ✓Left Shift-
Increased Breathing Rate Due To Less O2 To Decrease Co2= Alkalosis Event
What Does 2.3 Dpg Do? - Ans ✓Curves The Shift Back, Allowing O2 To Be
Released From The Tissues.
(Used In Times Of Altitude Sickness)
How Is Co2 Transported In The Blood? - Ans ✓Dissolved In Plasma, Bound To
Hemoglobin/ Protein, Or As Bicarbonate Ions In Plasma
What Is The Haldane Effect? - Ans ✓The Lower The Po2 And Hemoglobin
Saturation With O2, The More Co2 Can Be Carried In The Blood.
What Is The Bohr Effect? - Ans ✓The Regulation Of Hemoglobin Binding By
Hydrogen Ions And Carbon Dioxide
