Start with one diagram and a blank page
Look at a diagram from class, put it away, and sketch the main structures from memory. Label as many as you can, then check the sketch against your course material. Keep a short list of labels you missed so you can revisit them later.
Say what each structure does
After labeling a structure, write one sentence connecting it to its job. For the heart, the left ventricle pumps blood to the body. Use an arrow to trace where blood goes next, then explain the path in your own words.
Try it yourself
You can label a diagram while looking at it. How can you check whether you can recall the labels independently?
Show the answer
Cover the labels or use a blank copy, name the structures from memory, and check afterward. Revisit the labels you missed in your next session.
