histamine is actually the wrong answer! it is interferons (which are proteins) and they are called that because they "interfere" with the virus.
Toenails grow to protect the tips of our toes and provide support for them. They are made of a protein called keratin, which helps to strengthen and shield the sensitive skin underneath. This helps prevent injuries and infections, and also aids in gripping and balance while walking or running.
Saliva contains lysozyme, which is an antibacterial enzyme that helps protect the mouth from bacterial infections.
The filaggrin protein helps to maintain the skin barrier function by binding to keratin fibers in skin cells, promoting their aggregation and strengthening the skin's protective outer layer. This helps to prevent water loss and protect against external irritants, maintaining the skin's overall health and integrity.
The skin acts as a barrier to protect the body from harmful substances, pathogens, and UV radiation. It also helps regulate body temperature and prevent dehydration. Additionally, the skin contains immune cells that help defend against infections.
Skin is made up of various types of cells, including keratinocytes, melanocytes, and Langerhans cells. Keratinocytes are the most abundant and produce the protein keratin that provides strength and protection. Melanocytes produce melanin, the pigment that gives skin its color and helps protect against UV damage. Langerhans cells are part of the immune system and help protect against pathogens.

Yes, tears do contain lysozyme, an enzyme that helps protect against bacterial infections by breaking down the cell walls of certain bacteria.
I really don't know the answer that's why I'm asking a question.

Lingual tonsils are located at the base of the tongue, near the junction of the oral cavity and pharynx. They are a collection of lymphoid tissue that helps protect against infections.
No, it is not an organism. It is a component of an organism, which is an animal.
Interferon is the substance that causes noninfected cells to form an antiviral protein. It is produced by the immune system in response to viral infections and helps neighboring cells defend against viral invaders.
Keratin is the protein in the epidermis that helps protect the skin and underlying tissue. Keratin is strong and waterproof.
One of the most important guards against infections and germs is proper hand washing with soap and water.
