What are the components of the transport system in human beings? What are the functions of these components?


Transportation system present in human beings is the blood circulatory pathway which is double circulation i.e. one circulation from heart to organs and cells called systemic circulation and the other includes circulation between heart and lungs called pulmonary circulation. Blood, heart and blood vessels are the main components of the transport system.

  • Heart pumps blood to every part of the body.
  • Blood carries food and gases to every organ and cells, and
  • The blood vessels guide the blood to travel.
