Question

imflamation?

Answer 1

Inflammation is a defense mechanism of the body that involves complex biological responses to any harmful stimuli. Example - Harmful microorganisms, irritants, Injury, etc.

There are 5 Cardinal signs of Inflammation 1. heat(calor), 2. pain(dolor), 3. redness(rubor), 4. swelling(tumor), and 5. loss of function(functio laesa).

Inflammatory process

• When there is any damage occurs to body tissue they release some chemicals called histamine, prostaglandins, and prostaglandins.
• In response to this vasodilation occurs, which resulted in increased blood flood to the damaged area. It Increases the temperature of that area(Heat), causes redness due deposition of blood, and also causes leakage of blood plasma out of vessels to extracellular space which causes swelling.
• At this stage releases of a chemical called bradykinin increases the sensitivity of nerve cells to pain.
• Increases sensitivity to pain causes loss of function.
• Increased blood flow also helps immune cells (Neutrophil, macrophages) to reach near injury areas.
• Immune cell kills bacteria and removes dead tissue and toxins which promotes healing.
