RESPONSE TO INJURY NURSING – Injury to any cellular component can lead to illness as the cells lose their ability to adapt.
RESPONSE TO INJURY NURSING – Infection
Infection follows the invasion of cells and/or tissues by living Microorganisms such as bacteria, viruses of fungi. Although nonliving objects may place an individual at risk for infection (as in the case of a splinter leading to infection in a finger), it is the actual invasion of microorganisms that causes the infection. Infection is that the invasion multiplication of being in or on body tissue that manufacture signs and symptoms similarly as an immune reaction. Such copy injures the host by inflicting cell harm from microorganisms produces toxins or from living thing multiplication, or by competitory with host metabolism. Infection diseases vary from comparatively delicate sicknesses to fatal and exhausting conditions from communicable disease to non-inheritable immune deficiency syndrome. The severity of the infection varies with the pathogenicity and variety of the invasive microorganisms and also the strength of the host defenses
RESPONSE TO INJURY NURSING – Inflammation
Inflammation is a basic pathophysiological response to injury, is present in some form in all- multicellular animals. Injury triggers a complex series of interdependent reactions that serve to bring phagocytes into the area to defend against invasion by microorganisms and also set stage for repair of injury through proliferation connective tissue cell and collagen production. The majority of injuries result only in a local inflammatory response, a major injury due to trauma or virulent infection results in systemic signs of inflammation characterized by fever and leukocytosis. Inflammation is a complex reaction to injury or death of cells or tissues.

Inflammation is a defense mechanism initiated to control and eliminate the Offending agent and prepare an environment conducive to healing and repair. Inflammation response can be divided into a vascular response is a response to formation of exudates and healing process.
RESPONSE TO INJURY NURSING–Vascular Response
After cell injury, arterioles in the area ~undergo transient vasoconstruction. Injured cells release histamine which causes dilatation of blood vessels. This Vasodilatation result in hyperemia (increased blood flow in area).
RESPONSE TO INJURY NURSING–Cellular Response
cellular response – Phagocytes, i.e., neutrophils and monocytes, move lo the inner surface of the capillary wall to the site of the injury.
Exudate Formation- Exudate consists of fluid and blood disease that move from the circulation to thesite of injury. The nature and quantity of exudates depend on the type and severity of the injury and tissues involved.
The final part of the inflammatory response is healing. Healing includes 2 major elements of regeneration and repair. Regeneration is that the replacement of lost cells and tissues
