Where Erythrocytes and Leukocytes Are Made

Where red blood cells (erythrocytes) and white blood cells (leukocytes) are made, demonstrate your understanding of what causes blood types to be what they are by explaining what AB blood is regarding its antigens and antibodies.

State in which structure all erythrocytes and leukocytes are made. Include an accurate and complete definition of antigen AND antibody in terms of an AB blood type (must be for AB blood only). Describe in which structure a B cell is trained. Describe how (what does it need) a B cell is trained. Describe what a B cell makes to fight infection. Use the example of a pathogen in how a B cell is trained. Accurately infer what the direct cause of bumps (not general swelling) forming on the neck area when one is ill is.
