• True

• False

Inflammation is a complex reaction of vascularised tissue to an injurious stimulus.

• True

• False

What is the first response of arterioles to injury?

• Vasodilation

• Vasoconstriction

• Edema

• Redness

All of the following vascular changes are observed in acute inflammation, except:

• Vasodilation

• Stasis of blood

• Increased vascular permeability

• Decreased hydrostatic pressure

Which immune cell is responsible for the quickest release of histamine that causes the red itchy welts associated with allergies?

• lymphocytes

• mast cells

• Eosinophils

• Basophils

After a mini-exam, you and a couple of friends spend the weekend on the beach in St. Martin. At the end of the day, one of your friends complains of sunburn. His back is very red, warm and painful to touch. What is the most likely cause of this erythema?

• ischemia

• Edema of the dermis

• Vasodilation of blood vessel in dermis

• Bradykinin

Approximately 30-60 minutes after being bitten by a "bug", a 26-year-old man noticed a localized swelling and erythema in the affected area. The edema is most likely the result of:

• Altered plasma osmotic pressure

• Increased vascular permeability

• Vasoconstriction

• Lymphatic obstruction

The following few questions are about the chemical mediators of inflammation:

What is the main effect of histamine?

• pain

• fever

• smooth muscle contraction

• dilation of arterioles

What is the term used to describe white blood cells migrating toward bacteria?

• zeiosis

• phagocytosis

• chemotaxis

• phototaxis

Name the process a cell such as a neutrophil or a macrophage uses to ingest (eat) its prey.

• Phagocytes

• Phagosome

• Phagolysosome

• Phagocytosis
