Innate immunity is comprised of different components including physical barriers (tight junctions in the skin, epithelial and mucous membrane surfaces, mucus itself); anatomical barriers; epithelial and phagocytic cell enzymes (i.e., lysozyme), phagocytes (i.e., neutrophils, monocytes, macrophages), inflammation- ...
The main components of the innate immune system are 1) physical epithelial barriers, 2) phagocytic leukocytes, 3) dendritic cells, 4) a special type of lymphocyte called a natural killer (NK) cell, and 5) circulating plasma proteins.
The innate immune system includes:Physical Barriers. such as skin, the gastrointestinal tract, the respiratory tract, the nasopharynx, cilia, eyelashes and other body hair.Defense Mechanisms. such as secretions, mucous, bile, gastric acid, saliva, tears, and sweat.General Immune Responses.
(ih-NAYT ih-MYOO-nih-tee) Immunity that is present at birth and lasts a person's entire life. Innate immunity is the first response of the body's immune system to a harmful foreign substance.
Antibodies are the component which doesn't participate in innate immunity. The antibodies are part of acquired immunity which gets activated after exposure to the pathogen.
Examples of innate immunity include: Cough reflex. Enzymes in tears and skin oils. Mucus, which traps bacteria and small particles.
Cytokine barriers- the cells which have been infected by virus starts secreting interferons which prevents the spread of infection. They protect the non-infected cells from infection. Note:Immunity present by birth is called innate immunity, it is of four types; physical, physiological, cellular and cytokine.
A) Innate defenses involve physical barriers, cells, bloodborne chemicals, and inflammatory responses, while adaptive defenses primarily utilize lymphocytes and antibodies.
Answer and Explanation: The correct answer is option b. Innate immune responses represent the first line of defense against invading pathogens because the innate immune... See full answer below.
