Study Notes
Inflammation Overview
- Inflammation is a fundamental biological response to injury or infection.
- Its purpose is to destroy infectious and harmful organisms, isolate the infection, enhance the immune response, and stimulate tissue healing.
- Inflammation is characterized by immediacy, nonspecificity, and self-limiting nature, occurring in vascular tissues. It does not have memory.
Learning Outcomes
- Students should be able to summarize the purpose and physiological significance of inflammation in the immune response.
- They need to examine the characteristics and components of the inflammatory process.
- Students must compare/contrast the roles of cells, mediators, and plasma protein systems involved in the inflammatory response.
- Arrange the events of inflammation activation in sequence.
- Predict clinical manifestations of inflammation based on underlying mechanisms.
Case Discussion Questions
- Identify the cells that respond to inflammatory conditions.
- Explain the order of cellular responses.
- Explain the function of each cellular player.
- Discuss the pathophysiology behind inflammation symptoms (pain, warmth, redness, edema).
- Describe the function of plasma protein systems.
Components of Inflammation
- Cells: Different cells (e.g., mast cells, neutrophils, monocytes/macrophages, eosinophils, basophils, and platelets) play crucial roles.
- Inflammatory chemicals: These chemicals initiate and regulate the inflammatory response.
- Plasma protein systems: Three key systems are involved in inflammation: complement, clotting, and kinin systems. They interact to promote crucial processes.
Activation of Inflammation
- Cellular injury and pathogenic invasion trigger inflammatory responses.
- Activation of plasma protein systems (complement, clotting, and kinin) occurs.
- This leads to various local manifestations, including vasodilation, vascular permeability (edema), cellular infiltration (pus), thrombosis (clots), and nerve stimulation (pain).
Local Manifestations
- Inflammation exhibits local characteristics such as heat (redness), pain, swelling, and loss of function.
- These manifestations are visible signs of the response.
Systemic Manifestations
- Systemic manifestations may include fever, leukocytosis (increased white blood cells), increased circulating plasma proteins, elevated ESR (erythrocyte sedimentation rate), and decreased albumin levels.
3-2-1 Reflection
- Students should reflect on three key concepts learned about inflammation.
- They should identify two ways this knowledge will impact their future practice.
- A single question they still have regarding inflammation should be noted.
One Minute Paper
- Students should list the seven cells involved in the inflammatory response and characterize their unique properties.
