The correct answer is b) phagocytic cell.
Dendritic cells, including Langerhans cells, are a type of antigen-presenting cell found in the skin and mucosal tissues. They play a crucial role in the immune system by capturing and processing antigens, and then presenting them to T cells. This function is essential for initiating and regulating the body’s immune response.
These cells are specialized to detect and process pathogens. While they have a variety of morphological and functional characteristics, they are primarily recognized for their ability to phagocytize (or engulf) foreign particles, which is why they are classified as phagocytic cells.
In contrast, the other options—squamous epithelial cells, nerve cells, and melanocytes—serve different functions in the body and do not represent the primary role of dendritic or Langerhans cells.
