IMMUNOLOGY

Detailed explanation-1: -Inflammation. Inflammation is a nonspecific mechanism generated by the host in response to an infectious, physical, or chemical injury with recruitment of peripheral blood leukocytes and plasma proteins to the site of injury or tissue damage.

Detailed explanation-2: -Inflammation is the body’s normal, protective response to injuries or infections.

Detailed explanation-3: -The innate immune system The non-specific response is a generalized response to pathogen infections involving the use of several white blood cells and plasma proteins. Non-specific immunity, or innate immunity, is the immune system with which you were born, made up of phagocytes and barriers.

Detailed explanation-4: -The widening (dilation) of the blood vessels and loss of fluid into the tissues can cause low blood pressure (hypotension). The clotting system can become out of balance, making it hard for blood to reach the body organs. Bleeding can also develop.

Detailed explanation-5: -When tissue is first injured, the small blood vessels in the damaged area constrict momentarily, a process called vasoconstriction. Following this transient event, which is believed to be of little importance to the inflammatory response, the blood vessels dilate (vasodilation), increasing blood flow into the area.

Detailed explanation-6: -Physical barriers, like skin and mucous membranes. Chemical deterrents, like antimicrobial enzymes in bodily fluids and stomach acid. Reflexes, like coughing and sneezing. Cells, like macrophages, basophils, and natural killer T-cells. 02-Feb-2022
