PTA1030: Inflammation and Healing

Why is the circulatory system important for tissue healing?

• The circulatory system helps regulate body temperature during tissue healing.
• The circulatory system produces antibodies to fight infection during tissue healing.
• The circulatory system delivers oxygen and nutrients to injured tissues and removes waste products.
• The circulatory system releases hormones that promote tissue healing.

What is phagocytosis?

• Process of cells releasing toxins into the environment.
• Process of cells dividing and reproducing.
• Process of cells exchanging genetic material with other cells.
• Process of cells engulfing and ingesting solid particles or other cells.

The classic signs and symptoms of inflammation include all of the following except:

• loss of function
• swelling
• redness
• decreased blood flow

Why is the histamine response important for the inflammation process?

• The histamine response inhibits blood flow and prevents immune cell recruitment.
• The histamine response has no effect on the inflammation process.
• The histamine response decreases the release of other inflammatory mediators.
• The histamine response helps to increase blood flow, recruit immune cells, and promote the release of other inflammatory mediators.

How does vasodilation occur in response to injury?

• Release of inflammatory mediators
• Decreased production of inflammatory mediators
• Constriction of blood vessels
• Increased blood flow

How do you know that a bacterial infection is present during the inflammatory process?

• Fever
• Coughing
• Headache
• Presence of pus
