The skin has a number of defenses against microbes. The keratinized cells of the stratum corneum, the outer layer of the skin, provide a waterproof and physical barrier that protects the lower levels of the skin. These dead cells slough off, so that underlayers are not damaged. The sebaceous glands of the dermis produce sebum, which provides additional waterproofing. The skin also has an "acid mantle," a layer of chemical protection against microbes. Lastly, the skin has immune cells known as dendritic cells that identify and engulf bacteria, then move them to immune system cells that can react. The dendritic cells in the skin are known as Langerhans cells. Mast cells in the skin are white blood cells that release histamine to start an inflammatory reaction to fight infection. All of these structures and processes defend the skin and, by extension, the interior of the body against microbes.

∙ 7y agoThe skin is the body's first line of defense against microbes. The skin epidermis serves as a mechanical barrier which prevents microbes to enter into the body. The skin also secrets sweat and sebum to make its epidermis surface acidic and this acidity will inhibit bacterial growth. The keratin of the skin provides resistance against acid, alkalis, and bacterial enzymes.

What covers your body and stops microbes from getting in?
Skin is the outer covering of the body that protects against microbes and germs.
What is not the protection of the skin?
The protection of the skin primarily involves the skin's ability to act as a physical barrier against external harmful environmental factors such as microbes, toxins, and UV radiation. However, the skin does not provide protection against internal diseases or conditions that can affect the body's organs or systems. Therefore, the skin's protective function is limited to external threats.
The skin acts as a barrier against germs and also controls body temperature?
True. The skin acts as a barrier against germs and also controls body temperature.
Which defense would the skin would be an example of?
It is considered a surface barrier.
Four important functions of the skin?
1.it acts as the 1st line of defence against microbes 2.it gives out sweat as an excretory product 3.it stores lipids and waters 4.the skin provides a relatively dry and semi-impermeable barrier to fluid loss
Which layer of skin is primary barrier against environmental hazards?
EPIDERMIS
What are the body's barrier?
skin acts as a natural barrier against harmful stuff :) So do tears, sweat and the stomach :)
Which of the following is a surface barrier to infection?
The (unbroken) skin is a natural surface barrier to infection. Then, first aid items such as pads, plasters and bandages, used with antiseptic creams or lotions.
What are the body's physical barriers to pathogen invasion?
Skin is a great barrier to invasion by microbes.
What is the body first line of defense against bacteria and viruses?
