1st Year Physiology

Being that you are a first-year physiology student, you must have been introduced to the basics on physiology. Do you believe that you were super attentive in class? The quiz below is based on basic cell epithelial and connective tissue, AP, nerves, muscle, brain, and blood. Give it a shot and test what you understood throughout your first year on the subject.
