An Initial Disturbance In A System Sets Off A Chain Of Events That Does Not Favor Stability And Often
Abruptly Displaces A System From Its Steady State: What Is That?
A. Positive Feedback
B. Negative Feedback
C. Disease
D. Homeostasis - A. Positive Feedback
Positive Feedback - -Less Common
- Snowball Effect (Some Pain/ Pressure Gets Worse And Worse)
- Examples: Clots, Sneezing, Childbirth
- When Childbirth Starts There Is An Increase In Hormone Production Which Progressively Gets Worse
- May Use Many Means To Correct One Imbalance(Not Stable)
- Moves Away From Equilibrium
Amplifies Change
More Of A Product = More Contractions, More Clotting Factors
Negative Feedback - - More Common
- Self Regulating System That Helps Keep The Balance (Increase Or Decrease Of Output/Production)
- If There Is Not Enough It Makes More, If There Is Enough It Stops Making It
- Resist Any Changes From Normal (Example = Glucose And Temp Regulation)
,-Example: Thermoregulation- Body Temp Decreases, Heating Mechanisms Activated (Shivering), Body
Temp Increases , Cooling Mechanisms Activated (Sweating)
Reduces Change
Disease - - The Disruption In Homeostasis Or Deviation From Normal
- Body Is No Longer Functioning Normally
- Cellular Process Leads To Disease
Homeostasis - - Dynamic Process That Is Always Shifting/Changing (Give And Take System)
- The Body Likes Things Just So (Temp, Ph, Dilution, Shape)
- Equilibrium Is Necessary For All Cells
- Stable Process, Self Regulating
- Can Affect Proteins To Be In Proper Function/ Form, Release Of Oxygen In The Muscles
What Organ Shrinks With Age?
A. Prostate
B. Gums
C. Heart
D. All Of The Above - B. Gums
Prostate Gland (Increase/Decrease) - - Chestnut-Shaped Gland At The Base Of The Urethra In Men
- Produces Fluid That Mixes With Sperm And Secretions Of The Seminal Vesicles
- Prostate Fluid Further Decreases Acidity, Increases Sperm Motility, And Prolongs Sperm Life
- Gets Larger In Size As Men Increase In Age And Can Cause Urethral Problems
Gums (Increase/Decrease) - - Around 40 Gums Start To Recede And Decrease In Size
,- Inflammatory Processes Destroy Gum Tissue Overtime And Can Cause Pockets Between The Tooth,
Which Can Trap Bacteria
Heart (Increase/Decrease) - - Can Increase In Size Slightly As You Age
- Depends One One's Heart Wall Muscles (Can Strengthen Heart Wall Muscle Through Exercise)
Which Of The Following Is True?
A. An Infant Will Have A Slower Heart Rate Than An Adult
B. The Elderly Have Better Temperature Sensations
C. There Are More Sweat Glands In An Elderly Person
D. There Is Less Thirst Perception In The Elderly - D. There Is Less Thirst Perception In The Elderly
There Is Less Thirst Perception In The Elderly (T/F) - True
- The Aging Process Alters The Psychological Control Systems With Thirst
- The Elderly Also Can Take Medications That Can Lead To Dehydration
- The Elderly Have Less Physical Activity That Does Not Stimulate The Thirst Perception
An Infant Will Have A Slower Heart Rate Than An Adult (T/F) - False
- An Infant/Child's Heart Rate Is Normally Slightly Faster Than An Adult's Heart Rate
The Elderly Have Better Temperature Sensations (T/F) - False
- Elderly's Senses Are Weaker As Opposed To Children And Adults
There Are More Sweat Glands In An Elderly Person (T/F) - False
- No Correlation
, Which Of The Following Is True?
A. Women Snore More Than Men
B. Men Have Higher Calcium Levels
C. Women Have A Lower Hemoglobin Than Men.
D. Men Have A Lower Creatinine Level Than Women - C. Woman Have A Lower Hemoglobin Than Men
Woman Snore More Than Men (T/F) - False
-No Correlation
Men Have Higher Calcium Levels (T/F) - False
- Men And Women Have The Same "Normal" Levels (8.8-10.6 Mg/Dl)
- Calcium Intake (Ages 19-50): 1,000 Mg Per Day
-Older Women Over Age 50 And Older, Men Over Age 70 Should Increase Their Calcium Intake To
1,200 Mg Per Day
Women Have A Lower Hemoglobin Than Men. (T/F) - True
- Oxygen Carrying Proteins Of Erythrocytes
- Females (12-18 = 12 To 16 G/Dl) (Older Than 18 = 12.1 To 15.1 G/Dl)
- Males (12-18 = 13 To 16 G/Dl) (Older Than 18= 13.6 To 17.7
Men Have A Lower Creatinine Level Than Women (T/F) - False
- Creatinine Levels Between Men And Women Usually Have No Correlation
- Usually Depends On How Active A Person Is
