  • However, the hemal system of sea stars distribute nutrients from the digestive tract while in humans nutrients are provided through blood the pyloric cecum at each of the arms of the starfish supplies nutrients to all parts of the body as well but does not form a system.
  • Circulatory system (16) first, study fig1-1, then read the following while still referring to the figure the circulatory system consists of the heart which is a four chamber suction and pressure pump that moves blood through two separate systems, one to and from the lungs and the other around the body.
