CRR HISTOLOGY Respiratory System
NOTE: The following questions are designed for introductory drill (i.e., to practice basic vocabulary and description of cell structure and function in the respiratory system).
These questions do not necessarily represent the quality of questions which will appear on the CRR Unit evaluation.
[An mp3 file of this question set has been recorded by SIUC Anthropology student M. Campbell.]
SAQ, Introduction -- microscopy, cells, basic tissue types, blood cells.
SAQ, Cardiovascular System.
SAQ, Renal System.
Multiple choice questions.
Point to an answer. Green color and bold indicates "CORRECT." Red color and italics indicates "Wrong answer."
(NOTE: In cases where all of the responses are correct, only "all of the above" will be indicated as correct.)
