What is a reaction to tissue damage caused by injury or infection called?

What is a reaction to tissue damage caused by injury or infection called?

What is inflammation? Inflammation is a response triggered by damage to living tissues. The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury.

What are the nonspecific defenses?

Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN. Specific defenses include antibody (more…)

Which is the most important nonspecific defense?

The Body’s MOST IMPORTANT Nonspecific Defense is the SKIN. UNBROKEN Skin provides a continuous layer that protects almost the whole body. Very Few Pathogens can penetrate the layers of dead cells at the skin’s surface.

What is specific and non specific immune response?

Immunity from disease is actually conferred by two cooperative defense systems, called nonspecific, innate immunity and specific, acquired immunity. Nonspecific protective mechanisms repel all microorganisms equally, while the specific immune responses are tailored to particular types of invaders.

What are the specific defenses and how do they defend the body?

Natural barriers and the immune system defend the body against organisms that can cause infection. (See also Lines of Defense.) Natural barriers include the skin, mucous membranes, tears, earwax, mucus, and stomach acid. Also, the normal flow of urine washes out microorganisms that enter the urinary tract.

What is the body second line of defense?

The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).

What is the definition of specific immune response?

Specific immunity is acquired during the organism’s lifetime and involves the activation of white blood cells (B and T lymphocytes), which distinguish and react to foreign substances. B lymphocytes (or B cells) operate by producing antibodies, proteins that neutralize foreign molecules (
