Chronic Inflammation Quiz

What are the causes of chronic inflammation?

• Only tissue destruction is extensive

• Prolonged exposure to water

• Recurrent attacks of acute inflammation

• Starts as slowly progressing chronic disease

What are the morphological features of chronic inflammation?

• Extensive vascular dilatation and congestion

• Abundant inflammatory fluid exudate

• Formation of giant cells is absent

• Tissue necrosis gradually replaced by fibrous tissue

What is the definition of granuloma in chronic inflammation?

• A type of acute specific inflammation

• Formation of granuloma is caused by type I hypersensitivity

• A focal accumulation of large number of macrophages

• Characterized by rapid onset and short duration

What is the immunologic basis of granuloma formation?

• Granuloma formation is caused by type III hypersensitivity

• Granuloma is a protective defense by the host

• Granuloma formation is triggered by type II hypersensitivity

• Granuloma formation is independent of immune response

What is the fate of tubercles in high immunity?

• Small foci are completely fibrosed

• No fibrosis occurs

• Large foci spread to surrounding tissues
