What does your circulatory system have in common with the United Parcel Service (UPS)?

•Like the UPS, your circulatory system is in the business of delivering things.

•Your blood provides the service of carrying materials to and from your cells 24-hours a day, 7 days a week, 165 days a year.

•The UPS carries packages…your blood carries materials such as oxygen, sugars, and waste products.
