Quizplus · Accepted Answer

Leukocytes, also known as white blood cells, are the body's main defense against invading pathogens such as bacteria, viruses, and fungi. They help to identify and destroy these intruders in order to protect the body from harm.

Cytokines (choice C) are signaling molecules that are released by cells in the immune system, and they play a key role in regulating the immune response. However, while cytokines can help to activate and mobilize leukocytes, they are not themselves part of the body's primary defense against invading pathogens.

Leptin (choice A) and cholecystokinin (choice B) are hormones that are involved in regulating appetite and digestion, respectively. While they are important for maintaining overall health, they do not play a direct role in the immune response.
