Your skin is the first line of defense against pathogens that try to enter the body.

Freckles are not part of the immune system; they are small, concentrated spots of melanin on the skin caused by genetics and sun exposure. While they can indicate an individual's response to UV radiation, they do not play a role in immune function. The immune system consists of various cells and organs that protect the body from pathogens, whereas freckles are simply a cosmetic feature of the skin.
All of the body systems work with the integumentary system.NervousCirculatory
No, they are not. There are two types, one produces salty water and cools your skin and the second is 'smelly' and is found in under the arms and around the groin. But none are involved in the immune system.

Immune system
Langerhans cells are a subset of dendritic cells that reside in the epidermis (Part of the immune system). They have long dendrites (like arms) that capture antigen in the skin, and when they find an antigen, they migrate to lymph nodes and present to T cells allowing the adaptive immune system to respond.
The immune system, specifically the innate immune system, works to destroy microorganisms that enter the body through the skin. Components such as phagocytes and natural killer cells help to identify and target these invaders for destruction.
Lysozymes
no, unless the immune system is compromised
Langerhans cells are epidermal cells that play a key role in the immune response by capturing and presenting antigens to immune cells. They are part of the skin's immune system and help in defending against pathogens.
