Microcirculation and Inflammation
- Progressive vasodilatation mainly affects arterioles in the microcirculation following injury.
- The earliest response to tissue injury in the microvasculature is the immediate vasoconstriction of arterioles to minimize blood loss.
- Increased blood volume in the microvascular bed results from vasodilatation, leading to redness and warmth at the site of acute inflammation.
- Progressive vasodilatation elevates local hydrostatic pressure, which can potentially lead to enhanced tissue swelling and edema.
- Swelling at the local site of acute inflammation is primarily caused by an increase in vascular permeability and fluid accumulation.
- Severe injury can lead to a longer duration of vasoconstriction in arterioles due to prolonged sympathetic stimulation.
- The bright reddish appearance around the red line in the Lewis experiment is referred to as flushing or hyperemia.
- Swelling or edema of the surrounding skin in the Lewis experiment is termed inflammatory edema.
- The red line appearing in the Lewis experiment is caused by localized vasodilatation and increased blood flow following injury.
- The process when leukocytes stick to the vascular endothelium and migrate through endothelial gaps into the extravascular space is known as diapedesis.
- The increased concentration of red blood cells in the microcirculation leads to raised blood viscosity due to both stagnation and reduced plasma volume.
- Starling's hypothesis states that outward movement of fluid from the microcirculation is caused by capillary hydrostatic pressure and osmotic forces.
- Characteristic inflammatory edema resulting from increased vascular permeability is typically called exudate.
- Inflammatory edema around the inflamed tissue is caused by increased fluid leakage from the microvasculature and high protein content in the interstitial fluid.
- Forces causing inward movement of interstitial fluid into circulation include osmotic pressure due to plasma proteins and lowered hydrostatic pressure within the capillaries.
- Classical signs of inflammation such as redness, heat, swelling, and pain are elicited by the combined effects of vasodilatation, increased permeability, and migration of inflammatory cells.
