Which of the following is a feature of the skin that offers immunoprotection?
A
Presence of Langerhans cells in the epidermis
B
Secretion of sebum by sebaceous glands
C
Formation of hair follicles
D
Production of melanin by melanocytes
Verified step by step guidance1
Understand the role of the skin in immunoprotection: The skin acts as a physical and chemical barrier to protect the body from pathogens. It contains specialized cells and structures that contribute to immune defense.
Identify the function of Langerhans cells: Langerhans cells are immune cells located in the epidermis. They are antigen-presenting cells that detect and process pathogens, initiating an immune response.
Examine the role of sebum secretion: Sebum, produced by sebaceous glands, has antimicrobial properties. It helps to inhibit the growth of certain bacteria and fungi on the skin's surface, contributing to immunoprotection.
Evaluate the formation of hair follicles: Hair follicles primarily serve structural and protective roles, such as reducing friction and providing insulation. They do not directly contribute to immunoprotection.
Analyze the production of melanin by melanocytes: Melanin protects the skin from UV radiation damage but does not directly play a role in immunoprotection. Its primary function is pigmentation and UV defense.
