The circulatory system

Functions of the Circulatory System

  • Respiration - delivers oxygen to the cells and removing carbon dioxide from them
  • Nutrition - carries digested food substances to the cells of the body
  • Waste Removal -  disposes of waste products and poisons that would harm the body if they accumulated
  • Immunity - helps protect the body from disease
  • Cellular Communication - the circulatory system provides a mode of transport for hormones
  • Thermoregulation - the circulatory system transports heat (can both warm and cool body)

Here you have some really useful videos about one of the most important system for our body!

Enjoy them!
