Pumps in Living Organisms

The movement of water by osmosis is only one way fluids are moved around. In more advanced animals, fluids (which include water) are moved by pumps. Usually, we call these pumps hearts. These pumps work in different types of circulatory systems.

• What is a closed circulatory system?
• Which type of circulatory system do you have?
• Which type of circulatory system does an insect have?
