Circulatory System

My Favorite system so far has been the circulatory system two facts I’ve learnt so far

  1. That the veins bring the blood back up to the heart.

2. That we recycle our blood and bring it back up to the heart.

I feel good about science so far this year 🙂

I have created a heart monitor exercise course with my friend and we will ask the class to check their heart rate before the exercise and then after to see what happens. What do you think?
