Describe briefly about acute vs chronic inflammation
Acute inflammation is a short-term response of the body to an injury or infection. It is characterized by redness, warmth, swelling, and pain at the affected site. Acute inflammation is the body's initial defense mechanism against harmful substances or pathogens, and it aims to eliminate the cause of injury or infection and initiate the healing process.
On the other hand, chronic inflammation is a prolonged and persistent response that occurs when acute inflammation fails to resolve. It can last for weeks, months, or even years. Chronic inflammation is often caused by autoimmune diseases, prolonged exposure to irritants or toxins, or unresolved infections. Unlike acute inflammation, chronic inflammation is characterized by the infiltration of immune cells and the destruction of healthy tissues. It can lead to tissue scarring and systemic effects, contributing to the development of various chronic diseases, such as arthritis, asthma, cardiovascular disease, and cancer.
In summary, acute inflammation is a temporary and beneficial response aimed at protecting the body from harm, while chronic inflammation is a long-lasting and damaging process that can contribute to the development of chronic diseases.
