Undifferentiated B-cells which become a ____ when stimulated by an antigen.
Mast Cell
Plasma Cell
Two types: B-cells (humoral immunity) and T-cells (cell-mediated immunity)
Lymphocyte
Mast Cell
This cell is called the body's "first line of defense". It is called this because it is the first defense cell to arrive at the site of injury and it has a great capacity for phagocytosis.

Healing preceded by the formation of granulation tissue. Involves loss of tissue and increased scar tissue. Excessive scarring in skin is called keloid formation. Edges of injury cannot be approximated by sutures - granulation tissue fills defect.
Primary
Secondary
Tertiary
Healing with very little or no granulation tissue formation. Healing of an injury in which there is very little loss of tissue. Ex. Surgical incision - incision edges joined by sutures with small clot and little granulation tissue.
Primary
Secondary
Tertiary
Infection occurs at the surgical site. Infected injury is left open and edges are not surgically joined until infection is controlled.

Secondary
Tertiary
