Erythrocyte

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

Which of the following are characteristics of a hemoglobin protein?

• It is composed of 4 globin chains

• It carries heme groups that each hold a Potassium atom

• It can carry 4 oxygen molecules

• It causes the blood to have its red color

Antigens are:

• found on the surface of red cells

What is the primary function of erythrocytes in the human body?
