Question

question 46 of 50
which does the work of the immune system?
a. lymphocytes
b. enzymes
c. hormones
d. neurons

Explanation:

Lymphocytes (such as B - cells and T - cells) are key components of the immune system. B - cells produce antibodies to neutralize pathogens, and T - cells help in cell - mediated immunity (e.g., killing infected cells). Enzymes are mainly involved in biochemical reactions (e.g., digestion, metabolic pathways). Hormones are chemical messengers for communication between cells (e.g., regulating growth, metabolism). Neurons are part of the nervous system and are responsible for transmitting electrical and chemical signals in the body.

Answer:

A. Lymphocytes
