Document Summary
If someone has hepatitis they have inflammation in the liver. Infection: inflammation due to biological agents: usually elicit a more intense and prolonged inflammatory reaction. Injury: excessive stimulation, or: the effect of an excessive stimulus upon cells and tissues. Exudation: outpouring of fluids, proteins and cells from vessels into interstitium or body cavities, exudate - is extravascular fluid rich in proteins and cells with a specific gravity of > 1. 020. Implies significant alteration in the normal permeability of small blood vessels in the area of injury. 1: because of the gap proteins begin to go out which also brings water across, this is facilitated by many chemicals histamine. Transudation: outpouring of fluid with little protein (albumin) with a specific gravity of < 1. 012, transudate: ultrafiltrate of plasma and it is usually due to hydrostatic imbalance, permeability is normal, not because of inflammation, just water (fluid) Process: vasoconstriction(brief, vasodialation histamine (other chemicals) It can be an exudate or a transudate.
