A cellular component of the innate defenses includes ________.

Explanation: Although it is ancient, the innate immune system is highly complex and consists of barriers to infection (epithelia of skin, gastrointestinal, respiratory, genitourinary tracts), antimicrobial peptides and proteins, humoral components (i.e. complement and opsonins) and cellular components (i.e. neutrophils, monocytes).

A cellular component of the innate defenses includes natural killer cells.

Innate immunity represents the first line of defense, whose characteristics are limited to being able to discriminate a microorganism and its nature, its action being very similar to most harmful agents.

Natural killer cells represent a subpopulation of lymphocytes found in the blood (5-10%) and in lymphoid tissues, especially the spleen, in addition to being found in large numbers in the liver.

Natural killer cells play a significant role in anti-infectious defense through their two main functions, cytotoxicity and cytokine secretion, being a component of the innate immune response.

Therefore, we can conclude that natural killer cells are lymphoid cells with high cytotoxic capacity that constitute an important component of the innate immune system.
