Transportation in Plants and Circulation in Animals

Transport’ means to carry things from one place to another. Have you ever wondered how in animals the useful substances are transported to other cells and toxic substances are removed? In larger organisms transport of nutrients, salts, oxygen, hormones and waste products around the body are performed by the ‘Circulatory system’. The circulatory system consists of the circulating fluids, the blood and lymph and the heart and blood vessels which form the collecting and transporting system.
