which is an immune response?\no the iris of the eye narrows when the eyes are exposed to bright light.\no langerhans cells transport harmful substances to white blood cells.\no muscles under the skin contract rapidly to adjust the bodys internal temperature.\no t cells signal b cells to adjust the ph of the blood.
Answer
Brief Explanations:
Langerhans cells are part of the immune - system. They are dendritic cells in the skin that can take up and process antigens and transport them to lymph nodes where they interact with white blood cells to initiate an immune response. The iris narrowing is a response to light (not immune - related), muscle contraction for temperature regulation is a thermoregulatory response, and T cells and B cells do not adjust blood pH as an immune function.
Answer:
Langerhans cells transport harmful substances to white blood cells.
