Question

Defense mechanisms that function to protect the body against many infectious agents are called a. acquired. b. innate. c. barriers to entry. d. immunity

Short answer

The defense mechanisms that function to protect the body against many infectious agents are called innate immunity.

Step-by-step solution

Read the question carefully

Defense mechanisms that function to protect the body against many infectious agents are called: a. acquired. b. innate. c. barriers to entry. d. immunity

Definition of Acquired Immunity

Acquired immunity refers to the specific defense mechanisms developed by the body to fight specific pathogens. This type of immunity is developed over time and is not the initial defense against infectious agents.

Definition of Innate Immunity

Innate immunity refers to the general, nonspecific defense mechanisms that protect the body against many different types of infectious agents. This type of immunity is present at birth and provides the first line of defense against infections.

Definition of Barriers to Entry

Barriers to entry are physical and chemical measures that prevent pathogens from entering the body. The skin, mucous membranes, and stomach acid are examples of barriers to entry. Although these mechanisms are important components of the immune system, they are not considered the overall defense mechanism.

Definition of Immunity

Immunity refers to the body's ability to defend itself against infectious agents, including pathogens and other foreign substances. It can be acquired or innate, but this term does not specifically refer to the defense mechanisms against many infectious agents.

Choose the correct answer

Based on the definitions of the options, we can conclude that the correct answer is: b. innate. The defense mechanisms that protect the body against many infectious agents are called innate immunity.
