The Circulation of the Blood

It gets everywhere does blood - only just over a gallon of it per body so it has to keep moving to get round in time. How it does this and what sort of stuff it is are all explained in this excellent - and originally Spanish - Cherrytree which, as well as providing a lively text, illustrates red cells, white cells, platelets (like ant's eggs), capillaries and clots, with a size and clarity you'll never see other than with the best microscope. Watch in amazement as the ever-vigilant neutrophil creeps forward on silent pseudopodia to capture, engulf and digest the invasive bacterium. This is a complete book of blood and of circulation too, so we discover heart structure and function, pulmonary veins carrying 'arterial' blood and how the liver cleans it for re-use, not to mention the lymphatic system (and, come to think of it, most circulation books don't). There is something here to stimulate the phagocytes of any budding biologist.
