When I was teaching a high school science course, I was conducting a lesson about the female reproductive system and asked my students to draw it. None of them drew it correctly! Even at the college level-- freshmen through seniors in my non-majors biology courses had no idea how to draw the female reproductive system.
One of my students drew the stomach connected via TUBE to the uterus. Another drew FOUR—yes FOUR—fallopian tubes! One drew a baby inside the stomach (in the digestive tract) … oy vey. I mean, that would be the most inconvenient source of indigestion... if there was a baby... in your ACTUAL stomach. Yikes!
