Agglutination occurs when blood type antibodies come into contact with blood type antigens to which they correspond. What is agglutination?
Red blood cells burst and die
Red blood cells are clumped together and become non-functional
Antibodies bind to the antigens and then render the red blood cell non-functional
A system in which transfusions can occur
Explain ways in which the physical structure of an erythrocyte complements or illustrates its function.
Biconcave shape increases surface area.
Cell fragments help clot blood.
Round sides provide easy movement through vessels.
No nucleus or organelles so they don't use up oxygen
