Verified by Toppr

  • Coelomates show the development of a circulatory system for the purpose of absorption of nutrients and its circulation throughout the body.
  • An important component of the circulatory system is a pigment containing fluid component called blood.
  • Blood is the liquid connective tissue that circulates in the entire body and serves various functions like carrying oxygen and carbon dioxide, hormones, nutrients, excretory substances etc.
