Circulation in animals

Within animal bodies, transport usually involves a circulatory system – a pump with valved vessels that moves fluid around the body. Take a closer look at animals, or animal organs to develop this idea.

Experiments

• Observing blood circulation in Asellus
  Mount an Asellus (a small crustacean) on a microscope slide and observe circulatory movements of fluid in is limbs and pleopod.
