About this site

blood.foundation is a reference on the foundations of blood science. The name describes the subject: the ideas the field is built on, set out in the order they depend on one another.

It is written for students, for people arriving from a neighbouring field, and for anyone who wants the structure of the subject before the detail.

This site describes what blood is and how it works. It is not medical advice.

What this site is not

It is not an organisation, a foundation in the legal sense, or a charity. It does not raise, accept or distribute funds. It sells nothing and carries no advertising. It is not connected with any organisation, company or institution whose name resembles this address.
