Hi, our names are Loic & Victor. We studied the questions 'Is there oxygen in the heart?' and 'What is the difference between a vein and an artery?'
We found that an artery is stronger than a vein and heart disease has been found in 3,000 year old mummies.
We also found that there is only oxygen on the left side of the heart.
We would also like to learn how the brain works.
