,Diarrhea Symptoms - CORRECT ANSWER-Loose, unformed,
or watery stools; Maybe accompanied by abdominal
cramping; May cause dry skin and mucous membranes
(dehydration); May be associated with nausea, vomiting, or
fever when due to viral infection
The stages of infection are - CORRECT ANSWER-Incubation,
Prodromal, Illness, Decline, and Convalescence
Duration of incubation - CORRECT ANSWER-Can be as short
as 24 hours (influenza) or years (tuberculosis)
All illnesses have a prodromal stage - CORRECT ANSWER-
False
Examples of symptoms of prodromal stage may include -
CORRECT ANSWER-Feeling "off" or minor throat irritation
Infection stage of peak signs and symptoms - CORRECT
ANSWER-Illness
,When the immune system and any treatments become
effective at decreasing pathogen numbers - CORRECT
ANSWER-Decline
Convalescence - CORRECT ANSWER-Period of healing after
the offending pathogen numbers have decreased to zero
Lines of defense against infection - CORRECT ANSWER-
Primary, Secondary, and Tertiary
Primary Lines of Defense - CORRECT ANSWER-Barriers -
Normal flora; healthy, intact skin; mucous membranes in
nares, trachea, and bronchi; nose hairs; cilia in nares,
sinuses, trachea, and larger bronchi; lysozymes in tears,
saliva, and urine; rich blood supply in gums; stomach acid;
bile (antimicrobial) in small intestine; normal peristalsis,
vomiting, and diarrhea; antimicrobial secretions from
normal flora in small intestine; mucus secretions from
epithelial lining of anus and urethra; urine acidity; mucus
membranes and acidity of vagina
Secondary Lines of Defense - CORRECT ANSWER-
Chemically activated by pathogen waste and secretion that
break down cells and tissues
, Examples of secondary lines of defense - CORRECT
ANSWER-Phagocytes that engulf pathogens; Complement
cascade; Inflammation; Fever
Components of Complement Cascade - CORRECT
ANSWER-Triggers chemicals that attack and rupture
pathogen cell wall; Signals basophils to release histamine,
causing inflammation
Inflammation is caused by - CORRECT ANSWER-Basophils
and histamine released from damaged cells
Inflammation is - CORRECT ANSWER-The dilation of blood
vessels, increasing their permeability, allowing more
phagocytes, oxygen, nutrients, and antimicrobial agents to
the affected area
Classic signs of inflammation are - CORRECT ANSWER-
Redness and warmth to the affected area
Tertiary Lines of Defense - CORRECT ANSWER-Cell-
Mediated Immunity and Humoral Immunity
