These solids are the organic and inorganic substances. It contains 90-92 0f water and 8-9 of solids. Plasma is the straw colored liquid component of blood. In our plasma, there can be antibodies against.blood cells red bllod cells white blood cells thrombocytes 6 7. All systems have the following characteristics: Made up of individual parts that work together as a whole Often connected to one or more systems If one part of a system is missing or damaged, the system will not function well or may not function at all.InflammationВ refers to the initial physiological response to tissue damage, such as that caused by mechanical, thermal, electrical, irradiation, chemical, or infection.Blood type is based on the presence or absence of 2 kinds of antigens on the surface of red blood cells.

The endothelial cells initially swell, then contract to increase the space between them, thereby increasing the permeability of the vascular barrier. Vascular PhaseIn the vascular phase, small blood vessels adjacent to the injury dilate ( vasodilatation) and blood flow to the area increases. Pain ( dolor) вЂ“ caused by stimulation of the local nerve endings, from mechanical and chemical mediatorsFigure 1 вЂ“ Redness (rubor) and swelling (tumour), both characteristic features of acute inflammation Phases of Acute InflammationAcute inflammation can be discussed in terms of two stages (1) the vascular phase, which is followed by (2) the cellular phase.

Rolling вЂ“ close contact with and roll along the endothelium Margination вЂ“ cells line up against the endothelium They are attracted to the site of injuryВ by the presence of chemotaxins, theВ mediators released into the blood immediately after the insult.The migration of neutrophils occurs in four stages (Fig. Cellular PhaseThe predominant cell of acute inflammation is the neutrophil. It may also help to remove pathogens and cell debris in the area through lymphatic drainage.

Free radical formation) mechanisms.Figure 2 вЂ“ TheВ stages of acute inflammation vessel vasodilation, exudate formation and neutrophil migration OutcomesFollowing the process of acute inflammation, there are several possible results: Lysozymes) or oxygen-dependent (e.g. The phagosome is then destroyed via oxygen-independent (e.g. Emigration вЂ“ cells move through the vessel wall to the affected areaOnce in the region, neutrophils recognise the foreign body and begin phagocytosis,В the process whereby the pathogen is engulfed and contained with a phagosome.

It can also cause continually rising pressures within the tissue, resulting in pain and destruction of local structures. Over time, the acute inflammation will cease and, if not surgically drained, the abscess will be replaced by scar tissue.An abscess can be a source for systemic dissemination of a pathogen, with the abscess acting as a harbour for the infection. ItВ forms when the primary insult is a pyogenic bacterium and extensive tissue necrosis occurs.The initial inflammatory exudate forces the tissue apart, leaving a centre of necrotic tissue with the neutrophils and pathogens. Pus contains necrotic tissue with suspended dead and viable neutrophils and dead pathogens. Chronic inflammation вЂ“В from a persisting insultAn abscess is a localised collection of pus surrounded by granulation tissue. Fibrosis and scar formation вЂ“ occurs in cases ofВ significant inflammation
