answer:

i might be wrong but i'm 100% thinking it is a)truck 1 carries oxygen and truck 2 carries carbon dioxide. the reason i say this is because the heart and lungs have two main systems known as respiratory system and circulatory system that take carbon dioxide and replaces it with oxygen, which it takes to the brain so you body can function. hope this sorry it so lately answered.
