Science primary 4 the human circulatory system

  1. 1. The Transport Systems
  2. 2. Transport system of a plant A network of food-carrying tubes that carries food from the leaves to the rest of the plant called as phloem A network of water-carrying tubes that carries water and minerals from the roots to the rest of the plant called as xylem is made up of
  3. 3. The human circulatory system blood which carries digested food, oxygen, carbon dioxide and nutrients around the body blood vessels which are tubes through which blood flow the heart which pumps blood to all parts of the body is made up of
  4. 4. Heart
  5. 5. Plant transport system Human transport system Similarities  Both systems perform the function of transporting materials  Both systems have tubes to transport materials Differences  Transport food, water and minerals  Transport oxygen, digested food, carbon dioxide, water and other materials  Made up of food- carrying tubes and water carrying tubes  Made up of the heart, blood and blood vessels  Food transported is produced by the leaves  Food transported is food that has been digested  No organ is used to pump the materials through the tubes  The heart pumps the blood through the blood vessels
  6. 6. Respiratory system Circulatory system Digestive system carry out life process work together to
