Type AB blood type has-- * 1. A & B antigens * 2.no A or B antibodies

# Fill in the blanks. Type O blood type has-- * 1. antigens on surface- * 2. antibodies in his plasma-

Type O blood type has-- * 1. no A or B antigen * 2. A & B antibodies

# Fill in the blanks. A person with Rh factor present has-- * 1. antigens on surface- * 2. antibodies in his plasma-

A person with Rh factor present has-- * 1. Rh is the antigen * 2. no Rh antibodies

A person who can only receive blood from only a type O donor is likely ....

Type O

A person who can only receive blood from a type A, B, AB, O donor is likely ....

* Type AB

A person who can only receive blood from a type A, or O donor is likely ....

Type A

For a blood transfusion to be successful what two things must be compatible?

ABO and Rh blood groups must be compatible between donar blood and patient blood.

What happens when the wrong blood type is transfused into a patient?

* Red blood cells from the donated blood will agglutinate. * Agglutinated RBCs can clog blood vessels and stop circulation. * Agglutinated RBCs also crack and release hemoglobin which is toxic outside the cells. Patient may die.

A transfusion may work if the recipient has a blood group that doesn't have any ______ against the donor's \_\_\_\_\_\_.

* antibodies * blood antigens

An antibody against the Rh factor is also called

anti-D antibody
