Heart (pump, when the heart contracts, the spaces closes and pushes out blood) Blood (transports oxygen and nutrients, keeps us warm) Blood transports waste, acts as a transport medium. We need it for our paths/systems to work. Nutrients needs to come to our cells, and oxygen helps it to get it to our cells. Blood is lots of water and we need water for chemical reactions to occur. The air, oxygen, will be transported to our circulatory system and transports. Digestive system is basically a tube and what happens is that it slightly changes shape and interior.
