The first six digits of a card number (including the initial MII digit) are known as the issuer identification number (IIN). These identify the card issuing institution that issued the card to the card holder. The rest of the number is allocated by the card issuer. The card number's length is its number of digits. Many card issuers print the entire IIN and account number on their card.

Whole blood is made up of red blood cells, white blood cells and platelets, all which are suspended in a fluid called plasma. Each of these components of our blood has a very specific and important job.Red blood cells contain hemoglobin, a type of protein that gives blood its red color, and are primarily responsible for carrying fresh oxygen throughout the body while removing spent carbon dioxide from the cells.f course, we donât have little vehicles speeding through our veins, so how does blood do this?
