DEFINE HOMEOSTASIS
CONDITION OF EQUILIBRIUM (BALANCE) IN THE BODY'S INTERNAL ENVIRONMENT DUE TO THE CONSTANT INTERACTION
EX: PLAYGROUND, EVERYONE'S PLAYING NICE
-
WHAT ARE THE 3 BASIC COMPONENTS OF A FEEDBACK SYSTEM?
- RECEPTORS- MONITORS CONTROLLED CONDITION
- CONTROL CENTER- RECEIVES INPUT AND PROVIDES OUTPUT
- EFFECTORS- BRING ABOUT CHANGE IN CONTROLLED CONDITION
-
NEGATIVE FEEDBACK LOOP
RESPONSE REVERSES THE STIMULUS- OUR BODY DOESN'T WANT IT TO HAPPEN, SO IT DOES SOMETHING TO FIX IT- THEY WANT SOMETHING TO STOP
*THE MAJORITY OF FEED BACK IN THE BODY IS NEGATIVE
-
POSITIVE FEEDBACK LOOP
RESPONSE ENHANCES OR INTENSIFIES THE STIMULUS- WANT SOMETHING TO KEEP GOING, CONTINUES UNTIL SYSTEM IS DEPELTED OR STIMULUS GOES AWAY OR PROBLEM IS RESOLVED
-
3 EXAMPLES OF POSITIVE FEEDBACK:
- *BLOOD CLOTTING
- *CHILDBIRTH
- *SEVERE BLOOD LOSS
-
3 EXAMPLES OF NEGATIVE FEEDBACK:
- *BODY TEMP
- *BLOOD GLUCOSE
- *BLOOD PRESSURE
-
WHY IS NEGATIVE FEEDBACK THE MOST COMMONLY USED MECHANISM TO MAINTAIN HOMEOSTASIS?
THEY ARE SELF REGULATING, THERE IS SOME PRE-EXISTING SETPOINT AND WHEN THE SYSTEM RETURNS TO THAT NORMAL RANGE, THE FEEDBACK LOOP IS SHUT DOWN WITHOUT FURTHER INTERVENTION
-
COMPARE AND CONTRAST POSITIVE & NEGATIVE FEEDBACK
- *POSITIVE REINFORCES CHANGE, WHERE NEGATIVE REVERSES CHANGE
- *POSITIVE ACTION CONTINUES UNTIL INTERRUPTION, WHERE NEGATIVE ACTION STOPS AUTOMATICALLY WHEN SETPOINT IS REACHED
- *POSITIVE REINFORCES CONDITIONS THAT DON'T HAPPEN VERY OFTEN, WHERE NEGATIVE REGULATES CONDITIONS THAT REMAIN FAIRLY STABLE OVER LONG PERIODS
-
HOW DO DISRUPTIONS IN HOMEOSTASIS LEAD TO DISEASE?
YOUR BODY HAS NARROW LIMITS, WHEN SOMETHING AFFECTS THAT THE SETPOINT OF HOMEOSTASIS IS DISRUPTED, IF THE INBALANCE IS MODERATE THEN A DISEASE OCCURS, IF SEVERE, THEN DEATH
-
SIGNS
WHAT WE SEE
EX: RASH, SWELLING, PUS, VOMITING...
-
SYMPTOMS
WHAT THE PATIENT FEELS INTERNALLY
EX: NAUSEA, PAIN, SHORTNESS OF BREATH, HEADACHE...
-
SYNDROME
SET OF SIGNS AND/OR SYMPTOMS THAT OFTEN OCCUR TOGETHER
-
METABOLIC SYNDROME
(EX OF SYNDROME)
- FOUR SIGNS OCCUR TOGETHER:
- HYPERTENSION
- DYSLIPIDEMA
- OBESITY
- TYPE II DIABETES
-
COMPARE AND CONTRAST DISEASES FROM INTERNAL AND EXTERNAL SOURCES...
INTERNAL (AUTOIMMUNE DISEASES) ARE CAUSED BY GENETIC FACTORS AND EXTERNAL (INFECTIOUS DISEASES) ARE CAUSED BY ENVIRONMENTAL FACTORS
-
HOW ARE INFECTIONS SPREAD THROUGH POPULATIONS?
- MODES OF DISEASE TRANSMISSION:
- *CONTACT TRANSMISSION
- *COMMON VEHICLE TRANSMISSION
- *AIRBORNE TRANSMISSION
- *VECTOR TRANSMISSION
-
CONTACT TRANSMISSION
- DIRECT (TOUCHING, KISSING...)
- INDIRECT (FOMITES: SHARED OBJECTS)
- DROPLET (DISTANCE <1 METER)
-
COMMON VEHICLE TRANSMISSION
CONTAMINATED FOOD, WATER, BLOOD
-
AIRBORNE TRANSMISSION
PATHOGENS STAY ALIVE IN DROPLETS OR DUST TRAVELING >1 METER
-
VECTOR TRANSMISSION
- ORGANISM THAT TRANSMITS DISEASE
- TICKS, MOSQUITO, FLIES
* CARRIER- IF THE VECTOR DOES NOT APPEAR TO BE ILL
-
AN INFECTIOUS DISEASE AQUIRED IN A HOSPITAL?
NOSOCOMIAL
-
EXOGENOUS
TRANSMITTED FROM EXTERNAL ENVIRONMENT
-
ENDOGENOUS
INFECTIONS ARISE FROM ORGANISMS ALREADY PRESENT
-
