Question 7 1 pts Acute inflammation is a defense mechanism of the immune system. All of the following is a benefit of inflammation except ONE. Select the exception. enlargement of blood vessels inflammation triggers antimicrobial peptides O increases the rate of tisssue repair diapedesis

Answer 1

ans. enlargement of blood vesaels is not a beneficiary for acute inflammation process. although acute and chronic inflammatory processes are associated with the growth and/or enlargement of blood and lymphatic vessels. to allow accumulation of blood cell at wound site.

Antimicrobial peptides play a major role for the antimicrobial defense at all these stages in wound healing, but the main sources of antimicrobial peptides vary with the different stages of wound healing coming from plasma proteins and neutrophils. Apart from being part of the antimicrobial defense, antimicrobial peptides play other important roles in wound healing as in angiogenesis, attraction of leukocytes and resolution of inflammation. antimicrobial peptides mainly synthesize by neutrophils in inflammatory stage.

diapedesis - the passage of blood cells through the intact walls of the capillaries, typically accompanying inflammation.

Inflammation plays an important role in tissue repair and regeneration. Recent work reveals that inflammatory signaling increases DNA accessibility so as to promote phenotypic fluidity in response to injury.
