Exam Review
How Does The Effectiveness Of The Lungs Affect The Rate Of Gas Diffusion?
If The Lungs Are Not Effective At Taking In Oxygen And Getting Rid Of Carbon Dioxide Then Then
Gas Diffusion Will Not Be Able To Occur
How Does Inspiration Affect Lung Volume And Air Pressure?
Lung Volume Increases
Air Pressure Is Lower Within The Lungs Than Outside So Air Rushes In
How Does Expiration Affect Lung Volume And Air Pressure?
Lung Volume Decreases
Air Presses Is Higher Outside Than In The Lungs So Air Is Forced Out
When Would You Expect To Find The Highest Rate Of Air Pressure During Breathing?
Expiration
When Would You Expect To Find The Lowest Rate Of Air Pressure During Breathing?
Inspiration
, What Role Does The Pulmonary Artery Play In Respiration?
How Do Your Rib Muscles And Diaphragm Play A Role In Breathing?
Muscles Attached To The Rips And Diaphragm Move To Allow For Inspiration Of Expiration
Describe The Process That Allows Oxygen To Diffuse In Our Blood And Carbon Dioxide To Be
Released
-In The Lungs At The Alveoli, The Oxygen Is Picked Up By Passing Blood.
-High Oxygen In The Lungs Leads To Oxygen Loosely Binding To Hemoglobin Forming Forming
Oxygenhemoglobin
-Red Blood Cells Travel Through The Body Until They Find Areas Of Low Oxygen (Close To
Working Cells)
-The Oxygen Is Let Go And The Oxyghemoglobin Becomes Hemoglobin Again
-Some Carbon Dioxide Binds To Hemoglobin And The Rest Is Dissolved In The Blood -Red Blood
Cells Travel Through Veins Back To The Heart And Then To The Lungs To Release Carbon Dioxide
And Pick Up New Oxygen
Be Able To Identify The Components Of An Alveolar Sac On A Diagram
What Role Does Your Surfactant Layer Play In Respiration?
Surfactant Keeps The Alveoli From Collapsing In On Themselves, Which Would Block Diffusion
