This is an excellent resource attached with a fantastic detailed well understood video. The diagrams in the video help to understand the whole concept of the heart.<br /> Please do more of these videos <br /> The worksheet is also amazing too
Really nice quality worksheet - pleasantly surprised by how good the video was. Will there be more of these?
