3. The Body Systems

Here are the diagrams we will label in the videos in both unlabelled and labelled form. You can print them out and label them while watching the video or just use them as a resource for revision.

Also included are labelled photos of the dissected hearts used in the video.

Thats all for part 3.

I hope you have enjoyed learning about the cardiorespiratory system. I leave you with a photo of Fram studying very hard
