Swallowtail

Report

A useful GCSE science revision video on aerobic respiration, anaerobic respiration and the blood. The video is short but delivers the key facts clearly. This would be a useful aid to revision for any student studying these topics at GCSE.

Hi :))

in the video the tutor has recommended to watch a video about the structure of the hear and the function of the circularity system by a specific Dr. I did not catch with the name of the Dr. can anyone help me to spell the name. 

Many thanks.
