Formation of Exudate
The vascular response explains the accumulation of transudate in the extracellular space. As we know, transudate has approximately the same ionic composition as plasma, without the large proteins and cellular components of plasma. Once transudate has been at the site of injury for a period of time it starts to collect cells, cellular debris and proteins from the injured tissue. When the fluid in the extracellular space contains cells and protein it is called . This means that exudate reflects the degree of injury and the type of tissues involved. We classify exudate based on the cellular and protein contents of the fluid.
exudate is a watery, clear fluid that has a low cellular and protein content.
It is very similar to transudate in its content.
exudate is a result of the increased vascular permeability that occurs with tissue injury. Fibrinous exudate has high levels of the proteins fibrinogen and fibrin, as well as a high concentration of leukocytes. Fibrinous exudate can lead to the formation of in tissue that has been injured. exudate is pus. Suppurative exudate is composed of live and dead pathogen, live and dead leukocytes and necrotic tissue. Suppurative exudate is characteristic of bacterial infection. If suppurative exudate is contained in a circumscribed, localized area it is considered an abscess. Another term used to describe suppurative exudate is exudate. exudate involves mucus producing tissues and cells. Generally, catarrhal exudate is indicative of infection of mucous membranes by bacteria or viruses. Catarrhal exudate contains a high content of mucus, some leukocytes and some pathogen. exudate contains blood. For hemorrhagic exudate to occur there must be damage to blood vessels. Hemorrhagic exudate may contain pathogen as well as leukocytes.
Healing
Healing is the final stage in the inflammatory process. Healing can only occur once all pathogens and necrotic tissue is removed from the site of injury. The way in which tissue heals is dependent on the extent of damage, the type of tissue involved and the type of exudate that was formed during the inflammatory process. Without inflammation, some tissues will not heal. Healing is covered in depth in chapter 8 of this text.
