In my a&p 2 class today, we started the cardiovascular system. My first thought was ðŸ˜® that's a lot to remember! At the same time, it's actually pretty interesting to me, and it'll be fun to learn about. I definitely think it'll be the trickiest body system we have studied so far. How did you guys do with cardio? Did you find it to be more of a challenge than any of the other systems?
