Explanation:
Select the correct statement regarding tissue repair. Question 22 options: The clot is formed from dried blood and transposed collagen fibers. Granulation tissue is another name for a blood clot. Inflammation causes capillaries to dilate and become permeable. Granulation tissue is highly susceptible to infection.
The correct statement regarding tissue repair is: "Inflammation causes capillaries to dilate and become permeable."
Tissue repair is a complex process that occurs in response to injury or damage. Inflammation is the initial stage of tissue repair and plays a crucial role in initiating the healing process. During inflammation, capillaries in the damaged area dilate (widen) and become more permeable, allowing immune cells, growth factors, and other substances to enter the site of injury.
This increased blood flow and permeability of capillaries help deliver necessary nutrients, oxygen, and immune cells to the damaged tissue. It also helps remove waste products and dead cells from the site of injury. The influx of immune cells helps to remove debris and prevent infection.
The other statements in the options are incorrect:
1. "The clot is formed from dried blood and transposed collagen fibers": This statement is incorrect. The clot is formed from a process called coagulation, where platelets and clotting factors in the blood form a mesh-like structure to stop bleeding. Collagen fibers play a role in scar formation during the later stages of tissue repair.
2. "Granulation tissue is another name for a blood clot": This statement is incorrect. Granulation tissue refers to the new tissue that forms during the proliferative phase of tissue repair. It is characterized by the formation of small blood vessels, fibroblasts, and extracellular matrix. A blood clot is a temporary structure that forms to stop bleeding.
3. "Granulation tissue is highly susceptible to infection": This statement is incorrect. Granulation tissue is not highly susceptible to infection. In fact, it plays a crucial role in wound healing by providing a scaffold for the formation of new tissue. However, if proper hygiene and wound care measures are not followed, there is a risk of infection in any tissue, including granulation tissue.
