IMMUNOLOGY

Detailed explanation-1: -Nonspecific responses that alter the intracellular environment include fever, inflammation, and interferon. These multiple defenses function with great complexity because of their interactions with one another.

Detailed explanation-2: -Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body.

Detailed explanation-3: -there are two types: nonspecific, innate immunity and specific, acquired immunity. Innate immunity, with which an organism is born, involves protective factors, such as interferon, and cells, such as macrophages, granulocytes, and natural killer cells, and its action does not depend on prior exposure to a pathogen.

Detailed explanation-4: -So, the correct answer is ‘Killer T-cells’.

Detailed explanation-5: -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.

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
