Hello everyone, in the next section, I will discuss the pathology of inflammatory responses at the histological and clinical level. The first part will discuss the concept, the causes and symptoms of this disease.
What is inflammation?
Inflammation is the process of metabolism of tissues in the body in response to injury, a process that specifically affects the vascular-connective tissue.
Common causes of inflammation:
– Physics: trauma, thermal burns or cold or radiation burns
– Chemistry: including inorganic poison (chemical poison) and organic poison (organic poison)
– Biology: includes bacteria, viruses, parasites and immunity (humors and cells)
Inflammation occurs only in the connective tissue-blood vessels that surround the lesion; however, the organ’s parenchymal cells are not directly involved in this reaction.
The first stages are called acute inflammatory reactions, and as the process continues, the reaction turns into subacute or chronic inflammation.
Typical symptoms of inflammation (with Latin terminology)
Swelling: swelling, also known as tumor
Hot: heat, or calor
Red: redness, or rubor
Pain: pain, or dolor
Loss of function: loss of function, or functio laesa
These symptoms are explained by microscopic level changes. The three histological features of the reaction are:
2.Exudation of fluid
3) Emigration of leucocytes
