The Innate and Adaptive Immune
System and The Lymphatic
System
Anatomy and Physiology
Review
Instructions – Race To The Board
• The class will be divided into six separate
teams.
• One representative from each team will come
up to the whiteboard to answer a question (in
the PowerPoint) within a one minute time
frame.
• The first person to write the correct answer
on the board wins a point for his/her team.
Instructions Continued
• The Catch: The students at the board only get
ONE try to write the correct answer.
• If all students at the board answer the
question incorrectly, the first person from the
audience (on any of the teams) who raises
their hand and answers the question correctly,
earns a point for their team.
