Q

type 1 hypersensitivty

A

immediate reaction
- had to have been previously exposed (sensitization)

1st exposure: IgE: antibodies are made and attach to mast cells through the body

2nd exposure: antigen causes IgE to trigger T cells and histamine

Q

type 11 hypersensitivity

A

cytotoxic and cytolytic reaction
- igG and igM antibodies bind with antigen on cell surface

Q

right- sided heart failure

A
  • left-sided heart failure major cause must continually pump blood against increased fluid in the pulmonary artery and lungs
  • cor pulmonale: right ventricle hypertrophies and fails due to increased pulmonary pressures
  • a backward buildup of blood systematic blood vessels
  • peripheral edema results
  • backs into body= edema, jugular vein distension
  • body can attain a liter of fluid before showing signs: weigh pt.

Q

  • pvr influences afterload
  • hypertension major cause
  • blood backs up from left ventricle into lungs into pulmonary circulation= flooded capillaries
