How do you distinguish healthy from non-healthy immune cells? | Immune cells are the only cells capable of determining self from nonself. Self-tolerance is possible because of the different proteins present on all cell membranes. |
Cardinal Signs of Inflammation | Redness Warmth Swelling Pain Loss of Function |
Three Stages of Inflammation | 1. Vasoconstriction 2. Cellular 3. Healing |
VASOCONSTRICTION: Phase of Inflammation | due to trauma (vascular) Injury produces histamine and kinins Causes constriction of veins and dilates arterioles Redness and Warmth Fluid leaks out of cap into intestinal spaces of tissue Pain r/t prostaglandin release Edema protects from further i |
CELLULAR: Phase of Inflammation | mil-serious (dead WBCs) moderate - sangiounous/serosanguinous severe - purulent RBCs, dead and living bacteria |
HEALING: Phase of Inflammation | Healthy neutrophils Healing or Infection |
Specific Inflammatory Response | Involves antibody-mediated immune response and cell-mediated immunity Self recognize Has a memory Long lasting, generalized |
Non-Specific Inflammatory Response | rapid, short term, protective responses Bring fluid, dissolved substances and blood cells Occurs only in vascularized tissue helps start of the specific immune response |
Which cells provide protective responses during inflammation | Macrophages - protect and stimulate of longer lasting immune response |
