Inflammatory response (jove)

Question 1

What is the inflammatory response?

Answer 1

Is part of the immune system, acting as a localized, nonspecific reaction to injury or infection.

Question 2

What are the 2 key features of the inflammatory response?

Answer 2

• Localized Reaction
• Nonspecific:

Question 3

What is Localized Reaction of the inflammatory response?

Answer 3

• Localized Reaction: Occurs at the site of injury or infection.

Question 4

What is Nonspecific Reaction of the inflammatory response?

Answer 4

• Nonspecific: Not targeted at a specific pathogen but rather a general response to any damaging stimulus.

Question 5

What are the 5 symptoms of the inflammatory response?

Answer 5

• Redness: Caused by increased blood flow to the affected area.
• Swelling: Resulting from the accumulation of fluid in the tissues.
• Heat: Due to increased blood flow and metabolic activity.
• Pain: Triggered by inflammatory chemicals that stimulate nerve endings.
• Loss of Function: May occur in severe cases due to pain and swelling.

Question 6

What 4 triggers the inflammatory response?

Answer 6

• Physical Damage: Abrasions or cuts.
• Chemical Irritants: Substances that can cause tissue damage.
• Pathogens: Bacteria, viruses, or fungi.
• Extreme Temperatures: Both heat and cold can induce inflammation.

Question 7

What is the mechanism of the inflammatory response?

Answer 7

1. Injury or Infection: A damaging stimulus occurs.
2. Chemical Release: Damaged tissues and immune cells secrete inflammatory chemicals.
   
   • Histamine: Released by mast cells, increases blood vessel dilation and permeability.
   • Prostaglandins: Also released by mast cells, contribute to inflammation and pain.
3. Vasodilation: Increased blood flow leads to redness and heat.
4. Increased Permeability: Plasma fluid leaks into tissues, causing swelling and pressure.
5. Enhanced Immune Activity: Influx of immune cells (phagocytes) to the site of injury to combat pathogens and clear debris.

Question 8

What is the importance of the inflammatory response? (2)

Answer 8

-Accelerates Healing: The inflammatory response helps to clear out pathogens and damaged cells, facilitating tissue repair.
- Boosts Immune Function: Increases the activity of immune cells and enzymes that fight infections.

Question 9

What is the conclusion about the inflammatory response?

Answer 9

The inflammatory response is a vital mechanism that protects the body from harm and initiates healing processes.
