Skin cells are considered an external defense rather than an internal one. They form the outermost layer of the body, acting as a barrier to protect against pathogens, chemicals, and physical damage. This protective layer plays a crucial role in the immune system by preventing infections and maintaining overall skin health. Internal defenses, on the other hand, include components like white blood cells and other immune responses that operate within the body.

What two lines of defense does human skin have?
Human skin has two lines of defense: the physical barrier consisting of multiple layers of cells that prevent pathogens from entering the body, and the immune system, which includes immune cells that can attack and destroy any pathogens that manage to penetrate the skin.
What do ringworm's do to you inside your body?
Ring worm is a fungal infection of the skin. The fungi produces hyphae which invade the dead cells in your skin. However, the enzymes they produce irritate the living cells, which mount a defense. This causes the itchy, sore red areas.
Which of these does not belong Langerhans cells epidermal dendritic cells keratinocytes immune cells?
Keratinocytes do not belong, as they are the primary cells found in the epidermis that produce the protein keratin and serve a structural role in the skin, while the other three are immune cells involved in the skin's immune defense system.
What fights bacteria viruses and other foreign substance in the body?
The skin is your body's first defense in fighting infections and foreign substances. Your digestive system is your next defense.
Are T- Cells internal defenses?
Yes, T-cells are considered internal defenses as they are a crucial component of the adaptive immune system. They originate from bone marrow and mature in the thymus, where they develop the ability to recognize and respond to specific pathogens. T-cells play a vital role in identifying and eliminating infected or cancerous cells, thus contributing to the body's internal defense mechanisms against diseases.
List two lines of nonspecific defense with examples of each?
External defenses - Includes skin and mucous membranes. Internal defenses - Includes phagocytic cells, inflammatory responses, and antimicrobial proteins.
List two lines of nonspecific defense mechanisms with examples of each?
First of all, you might want to spell DEFENSE correctly.
What is contained in the epidermis?
The epidermis in humans contains cells (melanocytes) that make melanin, which gives skin its colour, Langerhans' cells which are the front line of defense of the immune system in the skin, and normal cells which make up your skin.
What two lines of defense does human skin have?
Human skin has two lines of defense: the physical barrier consisting of multiple layers of cells that prevent pathogens from entering the body, and the immune system, which includes immune cells that can attack and destroy any pathogens that manage to penetrate the skin.
Which of these is one of the body's first lines of defense against infection?
The skin is one of the body's first lines of defense against infection. Its physical barrier prevents pathogens from entering the body, while also producing antimicrobial substances to fight off potential invaders.
How does skin combat diseases?
skin is the body's first defense when it comes to bacteria. skin prevents direct contact of the body's internal systems with viruses and bacteria, therefore preventing disease.
Which of these is one of the bodys first lines of defence against infections?
its killer T cells

What organ is your first line of defense against pathogens?
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
Is the stratum spinosum the first line of defense?
No, the stratum corneum is the first line of defense in the skin against pathogens. It consists of a layer of dead keratinized cells that provide waterproofing and protect underlying layers of skin.
