What is connective tissue or blood tissue?
500
heart: pumps the blood around the body
Lungs: Ventilation takes place: O goes into the bloodstream and CO2 is removed from the blood and passes it into the air
Kidneys: filters the blood, excretes waste and helps maintain water balance

Teeth: helps to bite/tear/crush
