The heart, blood & circulatory system are usually covered in year 6. I won’t attempt to duplicate the multitude of excellent resources that are available: I here signpost you towards what I feel are most appropriate and add in my cross-curricular selection of activities to reinforce the learning.
Heart & lung dissection videos
This is the firm that I used to buy dissection supplies. They have excellent videos of all the common dissections & supporting lesson plans too. It’s NOT gory, I promise! You do need to register to view the content but it’s free and there are no resulting ads or hassle.
Beating heart gif
I use this on every heart lesson. Superb animation. Looks like heart has been cut in half but still beats, showing all the valves opening & closing. How quickly it beats depends on your computer!

SO many to choose from! Royal Society for Pathology has a stunning drawing to label & colour, plus a nice origami activity too.
