Last term, Drs. Peacock and Garry explained the feeding and breathing systems of plants and animals, and now they are to go on to explain how the useful substances of food and air reach the different regions of living things in order to refresh and repair them. This is performed by transport or circulatory systems formed of cells or of tubes which contain 'moving fluid. For example, the blood vessels and their blood in animals, and the wood vessels and the water in plants.
Today's talk by Dr. Peacock is to deal with some of the different kinds of hearts in various animals.
