BT_PO 1.126 Explain how the body defends against infection

T / F  IgG antibodies are released from memory B cells (plasma cells) as part of a secondary (learned) immune response.

T / F  “Innate” immunity would include intact mucosa, stomach acid, and lysozyme, but not neutrophils.

T / F  Administering tetanus vaccine is an example of an “active” way of providing acquired immunity.

T / F  The passive immunity provided to a neonate by trans-placental antibodies only lasts for about 1 month after birth.

T / F  The complement cascade results in lysis of bacteria. This can only be activated when IgG or IgM antibodies are bound to the bacteria.
