Based on the provided options, which characteristic is most likely associated with the instrument?

The instrument is present within the skin epidermis among squamous epithelial cells.

The instrument utilizes interferon type II for activation, analogous to macrophages.

The instrument can migrate across capillary walls, similar to eosinophils.

The instrument's capacity is to destroy invading bacteria in the respiratory system's exchange area. (correct)

Which of the following is NOT a characteristic of the foreign phagocyte described in the provided options?

Activation by interferon type II

Multiple nuclei in its cytoplasm (correct)

Movement in the blood with white blood cells

Cytoplasmic protrusions on its surface

What is a likely function of the cytoplasmic protrusions on the surface of the foreign phagocyte?

To produce signaling molecules for communication with other immune cells.

To facilitate the movement of the phagocyte through the blood vessels.

To help the phagocyte attach to and engulf foreign pathogens. (correct)

To increase the surface area of the phagocyte for better nutrient absorption.
