• Swelling

• Redness

• Spread of redness

Answer 1

Inflammation is often characterized by redness, swelling, warmth, and sometimes pain and some immobility. Inflammation is a vital part of the body's immune response. It is the body's attempt to heal itself after an injury; defend itself against foreign invaders, such as viruses and bacteria; and repair damaged tissue,

Causes-

Inflammation is caused by a number of physical reactions triggered by the immune system in response to a physical injury or an infection.

Inflammation does not necessarily mean that there is an infection, but an infection can cause inflammation.

Three main processes occur before and during acute inflammation:

• small branches of arteries enlarge when supplying blood to the damaged region, resulting in increased blood flow.
• Capillaries become easier for fluids and proteins to infiltrate, meaning that they can move between blood and cells.
• The body releases neutrophils. A neutrophil is a type of white blood cell filled with tiny sacs that contain enzymes and digest microorganisms.

A person will notice inflammation symptoms after these steps take place.

PURPOSE - Its purpose is to localize and eliminate the injurious agent and to remove damaged tissue components so that the body can begin to heal.
