NSAIDs

Nonsteroidal anti-inflammatory drugs

Is interferon part of the 1st, 2nd or 3rd line of defense?

2nd Line of defense

Which WBCs are associated with allergic reactions?

Basophils

Haw are mast cells different from basophils?

Bound to connective tissue around blood vessels, nerves and epithelia and are non-motile.

What is opsonization?

Coating antigen with complement enhances phagocytosis.

Blood is circulated by the heart, but lymph is circulated by what mechanism?

Contraction of the skeletal muscle

What do transferrins in the blood do to inhibit bacterial growth?

Decrease the amount of available iron.

Monocytes give rise to ? and ?, both of which are antigen presenting cells.

Dendritic cells & Macrophages

True or False High body temperature increases the amount of available iron for bacteria.

False **delays by reducing availability of iron

Pyrogenic

Fever

MAC is part of the complement syste,, a group of over 30 proteins produced by the liver and found in the blood. MAC stands for?

Membrane Attack Complex

List the WBCs that are phagocytic

Monocytes, Neutrophils and Eosinophils

During the inflammation response, vasodilation i an important part of diapedisis/extravasation. What is diapedisis/extravasation?

Phagocyte migration; phagocytes stick to endothelium and squeeze between epithelial cells.

In a normal healthy person, why does the body not attack itself?

Recognition of self = surface markers. Nonself cells are recognized by PRRs as either being a threat by identifying molecular patterns called PAMPs or if not harmful the immunes system will generally not respond.

Erythrocytes

Red blood cells

Describe the ciliary escalator

Respiratory tract; goblet cells produce mucus. respiratory epithelial cells have cilia which move mucus out of tract and prevents infection.

The four ways to remember the order of inflammation are redness, heat, swelling and pain. WHat are the Latin names of those steps?

Rubor, Calor, Tumor, Dolor

Scarring is a result of cell repair of the?

Stoma

The network of fibers that connects cells with each other and provides a support system for phagocytic immune cells is called what?

The reticuloendothelial system

Inflammation response process

Vasoconstriction, Vasodilation, Extravasation, Edema

Leukocytes

White blood cells

Thrombocytes

platelets

Pyogenic

pus-producing
