Question

Define Inflammation.

Answer 1

Hint: Inflammation is referred to as the process by which your white blood cells of the body and the products made by them protect you from infection from outside invaders, such as viruses and bacteria.
You must have noticed, when any wound swells up, it then turns red and also hurts, this is a sign of inflammation.

Complete answer:
Let’s understand inflammation as a physical local condition in which a specific part of the body becomes hot, swollen, red, and painful often, especially as a reaction to injury or infection.

In general, inflammation can be remembered as the body's immune response to any irritant that might be a germ, also can be foreign object.
On visual observation, inflammation is classified by ancients by five cardinal signs, namely swelling (tumour), loss of function (functio laesa), redness (rubor), heat (calor), and pain (dolor).
Pay attention, Inflammation is differentiated into two kinds:
- Acute or (short lived) and
- Chronic (or long lasting).

Acute inflammation usually goes within some days or hours. Whereas, Chronic inflammation can last years to months, still after the first trigger is gone. Conditions that may be linked to chronic inflammation include: asthma, cancer, diabetes, Alzheimer’s disease and more

Maybe in disease, like arthritis, our body's defence system that is our immune system in no time, triggers inflammation instantly when there are no invaders available to fight off. In case of these kinds of autoimmune diseases, our immune system will play a role as if regular tissues are infected , which will lead to damage.

Additional information:
Keep in mind, there are three stages of inflammation which can vary each in duration and intensity.
• Acute – This is a swelling stage.
• Sub-acute – This is a regenerative stage.
• Chronic – This is scar tissue maturation and also remodelling stage.

Note: Acute inflammation is the initial reaction or response of the body to stimuli that is harmful and is achieved by increasing the movement of leukocytes (especially granulocytes) ,and plasma from the blood into injured tissues. If inflammation is prolonged, referred to as chronic inflammation, results shift in the type of cells present at the site of inflammation, like mononuclear cells, and is characterized by simultaneous healing and destruction of the tissue from the inflammatory process.
