What is one type of white blood cell that participates in the specific immune response called? a. antigens b. antibodies c. macrophages d. pathogens

The right answer is C. macrophages.

A macrophage is one type of cells of the immune system. It is part of the white blood cells.

Macrophages have three main functions:

* phagocytosis (ingestion of bacteria, yeasts, cellular debris ...). The intracellular vesicle formed is called the phagosome, which will be directed to the lysosome for its complete degradation;

* secretion activity (cytokines ...);

* cellular cooperation (it is an antigen presenting cell, relationship with the lymphocytes).

They are therefore actors of innate immune response, since they phagocytose nonspecific elements. They are attracted to the place of inflammation by chemotaxis.

plz give me the characteristics.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
