Inflammation Process After Trauma
- Detection: Damaged cells release chemicals like histamine, bradykinin, and prostaglandins.
- Vasodilation: Blood vessels widen (vasodilation), allowing increased blood flow to the affected area.
- Swelling and Heat: Fluid leaks into tissues, causing swelling and localized warmth.
- Immune Cells Activation: Immune cells (like neutrophils) rush to the site to fight pathogens and initiate repair.
- Pain and Redness: Nerve endings are stimulated, leading to pain and redness.
- Healing: The process helps remove harmful agents and allows tissue repair to begin.

Innate Immunity
- Our body's 1st line of defense against invaders like viruses, bacteria, and toxins
- Detects these threats immediately and activates cells to attack or repair
- Modulates the "adaptive immune response," which involves specific immune cells that multiply and combat the invader, leading to recovery and protection against future attacks
