Title: Explain the host immune response to foreign substances.
Course: Medical Laboratory Technology II (14102-II) > Section: Understanding the Basics of Immunology/Serology

Explanation should include

- first line of defense against infection
  - components and general function of natural immunity (e.g., skin, mucus membranes, secretions)
- second line of defense
  - granulocytes/phagocytes
  - five steps and general activities in phagocytosis
  - inflammation
  - comparison of the cellular and humoral components of innate immunity (acute phase reactants, C-reactive protein [CRP])
- third line of defense (adaptive response)
  - function of adaptive immunity
  - types of lymphocytes and the function of each type
  - definitions and characteristics of antigen and antibody
  - five classes of antibodies.

Process/Skill Questions:

- How does a lymphocyte function?
- What is adaptive or acquired immunity?
- What characteristic in neutrophils demonstrates that they have performed phagocytosis?
