patho Flashcards
assesses WBC, RBC, hemoglobin/hematocrit, red blood cell indices, and platelets to determine general health, anemias, infections, blood cancers
CBC
ssesses 5 types of WBCs (basophils, eosinophils, monocytes, lymphocytes, neutrophils).
cbc W/DIFFERENTIAL
basic or comprehensive, assesses fluid and electrolytes status along with glucose, renal and liver function.
cmp
(risk for cardiovascular disease) LDL: <100 mg/dL (want it LOW) HDL: >60 mg/dL (want it HIGH); Total Cholesterol: <200 mg/dL; Triglycerides: <150 mg/ dL
LIPID PANEL
blood glucose levels for prediabetic
hemoglobin A1c / 5.6 pre-diabetic
powerhouse Cell, creates ATP, hundreds to thousands located w/i each cell
mtDNA -has it’s own DNA; cellular respiration
Mitochondria
contains DNA, RNA, proteins; nucleolus (RNA), chromosomes, surrounded by nuclear envelope (membrane)
nucleus
continuous from the nucleus, rough ER contains ribosomes which synthesize proteins from transcription of RNA
rough ER
continues synthesis, protein folding, storage & transport to Golgi; important in synthesis / storage of lipids & steroids
smooth ER
packages proteins to be excreted from the cell via membrane bound vesicles; RNA translation occurs to package the proteins into appropriate amino acid combinations
Golgi apparatus
Proteins or lipids that become glycated as a result of exposure to sugars
Leads to protein cross-linking & aggregation, resulting in altered cell signaling / functioning
AGE/ALE
medical name for dry skin.
Xerosis:
“Eczema” chronic itchy, dry red skin,
atopic dermatitis
dry mouth resulting from reduced or absent saliva flow.
xerostoma
abnormal dryness of the conjunctiva and cornea of the eye, with inflammation and ridge formation, typically associated with vitamin A deficiency.
xerophthalmia
Inflammatory triggers:
Toxic exposure (environment, pathogenic bacteria LipoPolySaccarides)
Allergenic response: IgE, IgG, (foods)
Oxidative stress
Dysglycemia
Inflammation (signs) and regeneration:
Vasodilation: heat, redness
Swelling, edema
Tenderness / pain
Regeneration: 1) homeostasis, 2) inflammatory, 3) proliferative, and 4) remodeling
Prevent or arrest clot formation; mast cells release it to stimulate local inflammation; anticoagulant used Tx thrombosis
Heparin
Stored in the granules of mast cells, basophils, platelets; acute inflammation, anaphylatoxins, and histamine releasing factors
histamine
polyunsaturated omega-6 fatty acid breaks down via phospholipase A2 into AA which breaks down into LOX / COX (collectively referred to as eicosanoids)
arachiodonic acid
serve general functions such as gastric epithelial cytoprotection and homeostasis.
COX 1
inflammatory: (blocked by NSAIDs; creates Prostaglandin H2
PGH2 converts to prostaglandins: helpful in stomach protective effects, causal of pain, fever
PGH2 converts thru platelets to thromboxanes (not good for heart),
PGH2 converts to prostacyclin (heart helpful)
COX 2
inflammatory response causes bronchial constriction, respiratory issues (asthma)
LOX converts to Leukotrienes
inflammatory! inhibited by NSAIDs & Aspirin
prostaglandins
From arachidonic acid by the action of cyclooxygenase (COX) isoenzymes; blocked by NSAIDs
Cause increased inflammation, blood flow, chemotaxis (chemical signals that summon white blood cells), and subsequent dysfunction of tissues and organs
prostaglandins
1st defense, QUICK response to acute invasion, large # chemical mediators, slows infectious process but does NOT eliminate pathogen
Innate immunity
2nd line defense; Slow responders, chronic longterm, creates immune memory; 2 types: humoral & cell-mediated
adaptive immunity
Physical and chemical barriers, such as skin, mucus membranes, tears, and stomach acid; Innate
1st line of defense
Non-specific responses to infection: inflammatory response & complement system; Innate
2nd line of defense
Adaptive/specific defense, such as lymphocytes, antibodies, plasma cells, memory B cells, T cells; Acquired
ADAPTIVE/3rd line of defense
enzyme that catalyses the formation of isopeptide bonds between proteins.
transglutaminase
used as a marker to diagnose celiac disease
transglutaminase
precursor to RBC, Platelets, Mast cell, 4 of 5 WBCs: Neutrophils, Mono, EOS, Baso
myeloid progenitor cells
located in Connective tissue throughout body, release histamine to ↑ vascular permeability so that during inflammation capillaries can leak protein rich fluid into injured tissue.
Mast cells
hemostasis, proper clotting
platelets
first stage of wound healing
hemostasis
wandering macrophages clean up debris & start healing process
monocytes
bilobed, fight parasites, food allergens
eosinophils
inflammatory response team, secretes lysozymes, defenisins,
basophils
become natural killer cells & lymphocytes: B-cells, T-cells, Th1, Th2
lymphoid progenitor cells
mature in Bone marrow, reside in lymph nodes
humoral immunity
B-cells
produce antibodies
circulate in blood, body fluids, binds to ANTIGENS to eliminate
major defense mechanism vs bacteria & toxins
require Th2 cells to function
b cells
mature in thymus and reside in lymph notes
t cells
main defense vs viral, fungal, parasitic invaders
eliminates abnormal cells
long life span
t cells
secretes pro-inflammatory cytokines; NKcells,
TH1
helps humoral B-cells, produces antibodies, secretes cytokines IL4, IL5, etc, promotes IgE production & activates eosinophils; 90% of AI are TH2 dominant
Th2
defensins: indicates inflammation response,
neutrophils
(1.5x larger than RBCs) ↑ EOS (>9) parasites, food allergies
eosinophils
