, BIOL 3201 IMMUNOLOGY - ASSIGNMENT 1 PREP WORKBOOK
ASSIGNMENT 1 PREP STRATEGY
The public BIOL 3201 course outline identifies Assignment 1 as covering Modules 1, 2, and 3. This workbook therefore emphasizes
explaining mechanisms, comparing immune components, applying concepts to short scenarios, and interpreting evidence - skills that
directly support the published course learning outcomes.
AREA WHAT TO BE ABLE TO EXPLAIN
Module 1 Innate vs adaptive immunity, barriers, recognition, protection versus regulation, and how the two arms cooperate.
Module 2 Functions of neutrophils, macrophages, dendritic cells, NK cells, lymphocytes, bone marrow, thymus, lymph nodes, spleen, and
lymphatics.
Module 3 PAMP/DAMP sensing, phagocytosis, complement, inflammation, cytokines, leukocyte recruitment, fever, interferons, NK-cell
activity, and resolution.
SECTION A: SHORT RESPONSE
Foundational concepts from Modules 1-3
01 Short Response
Explain why the immune system is described as both a protective system and a regulated system.
MODEL RESPONSE
The immune system must detect and eliminate infectious agents while limiting damage to the host. Protective mechanisms include
barriers, phagocytes, complement, antibodies, and lymphocytes. Regulation is equally important because excessive or misdirected
responses can injure healthy tissues, whereas inadequate responses can permit infection.
02 Short Response
Distinguish innate immunity from adaptive immunity using speed, receptor type, and memory.
MODEL RESPONSE
Innate immunity acts rapidly through germline-encoded pattern-recognition receptors that detect conserved microbial or danger
signals. Adaptive immunity usually develops more slowly on first exposure because antigen-specific B and T lymphocytes must be
activated and expand. Adaptive responses generate immunological memory, producing faster and often stronger responses on later
exposure.
03 Short Response
Describe three ways intact epithelial surfaces reduce the chance of infection.
MODEL RESPONSE
Epithelia provide a physical barrier through tightly connected cells, support mechanical removal through mucus and ciliary action, and
create hostile chemical conditions through antimicrobial molecules, low pH, or enzymes such as lysozyme. These defenses act before
microbes gain access to deeper tissues.
