"A free resource to help teachers and students to gain a deeper understanding of how the body works has been launched by The Physiological Society in partnership with the University of Liverpool.
The resource, a Massive Open Online Course (MOOC), has been specifically designed to support the A-level Biology curriculum, with a focus on the respiratory, cardiovascular and nervous systems."
A collaborative archive of teaching resources. Teachers may submit resources to be published as well. Came across this while looking for anatomy resources, but there are a lot of science resources here not restricted to anatomy.
