Question

1. what is the probable result of infusing mismatched blood? 14. cary is bleeding profusely after being hit by a truck as he was pedaling his bike home. at the hospital, the nurse asked him whether he knew his blood type. he told her that he “has the same blood as most other people.” what is his abo blood type? 15. what is the difference between an antigen and an antibody?

Explanation:

1. When mismatched blood is infused, the recipient's immune system attacks the donor red - blood cells, leading to agglutination (clumping) and hemolysis (rupture of red - blood cells), which can cause kidney damage, shock, and potentially death.
2. The most common ABO blood type in the general population is Type O. So, if Cary has the same blood as most other people, his ABO blood type is likely Type O.
3. An antigen is a substance (usually a protein or polysaccharide) that can trigger an immune response in the body. Antibodies are proteins produced by the immune system in response to an antigen. Antibodies bind specifically to antigens to help eliminate them from the body.

Answer:

1. Agglutination, hemolysis, possible kidney damage, shock, and death.
2. Type O
3. Antigen triggers immune response; antibody is protein produced in response to antigen and binds to it.
