Study Notes
Repair vs. Regeneration
- Regeneration restores original tissue architecture and function after injury.
- Repair replaces damaged tissue with connective tissue (scarring), altering both structure and function.
Acute Localized Venous Congestion
- Causes: Thrombosis, ligature, strangulation, or twisting of the pedicle.
-
Effects:
- Rapid and severe distention of veins.
- Edema develops quickly in the tissues.
- In the intestine, infarction and gangrene may occur.
Exudate vs. Transudate
-
Exudate:
- Present in inflammation.
- High protein content.
- Clots on standing due to fibrinogen.
- Contains inflammatory cells.
-
Transudate:
- Occurs due to conditions other than inflammation.
- Low protein content.
- Does not clot on standing due to lack of fibrinogen.
- Lacks inflammatory cells.
Types of Healing
- First Intention Healing: Occurs in wounds with clean opposing edges, like surgical incisions.
- Second Intention Healing: Occurs in wounds with separated edges, requiring more tissue for closure.
Classification of Edema
-
According to site:
- Localized Edema: Swelling in a specific area.
- Generalized Edema: Swelling throughout the body.
-
According to consistency:
- Pitting Edema: Soft edema that leaves an indentation when pressed.
- Non-Pitting Edema: Hard edema that does not indent with pressure.
Cardiac Edema
- Generalized edema caused by right-sided heart failure.
Benign vs. Malignant Tumors
-
Benign Tumors:
- Small, slow-growing.
- Non-invasive.
- Well-differentiated.
- Stay localized.
- Cannot invade or metastasize.
-
Malignant Tumors:
- Large, fast-growing.
- Invasive.
- Poorly-differentiated.
- Metastasize to other parts of the body.
- Infiltrate, invade, and destroy surrounding tissues.
Dystrophic vs. Metastatic Calcification
-
Dystrophic Calcification: Deposition of calcium in dead tissues.
- Example: Damaged heart valves.
-
Metastatic Calcification: Deposition of calcium salts in normal tissues.
- Example: Vitamin D intoxication.
