Body has it's own mechanism to defend itself. First of all, it has barriers like skin and mucus membrane to prevent entry of organisms in the body. Even if they enter the the body by means ofbreakage of barriers, body has it's own mechanisms to handle the same. It identify the foreign protein by different methods. One is called 'Innate immunity'. Means certain types of organisms are killed almost instantly. Which may cause severe disease in another animals or plants and vice verse. Even if a single microorganism enters the body, it is noticed by immune system of body. Any foreign protein is taken very seriously by the body. Chemicals released by microorganisms are noted and white blood cells (Polymorphocytes) migrate to the site by entering the capillary wall byamoeboidmovement. They engulf the bacteria and digest it. If microorganisms win, you may become ill. Eventually immunitydevelopsin your body to fight infection. Two types of lymphocytes also play a role in immunity. 'B' type cells produce 'humeralimmunity'. It means they start to produceImmunoglobulinsin due course of time. Usually 2 weeks and if you give anotherchallengelike you give injection of tetanus (Dead bacilli of tetanus.) after 4 to 6 weeks immunity will last for 6 to 9 months. If you give third dose, then protection increases to 5 years. If you give at 5 years the protection last for 20 years. If you take at 20 years you will not get tetanus for life. So whenever next attack comes body produce large amount of antibody if you periodically remind it. Or it may forget the attack. Another type of response is called as cell mediated response. It is mediated through 'T' cells which arises from 'Thymus gland' situated in thorax. These cell mediated immune response gives large number of 'T' lymphocytes by way of specific clone when ever there is attack by the same organism. And they destroy the invaders.

Can an intact skin surface be the best way the body can defend itself against pathogens?

How is skin a surface barrier against microbes?
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.
What does the stomach contain to defend your body against microbes?
The stomach contains acids that defend your body against microbes. Most of these microbes are destroyed once they are digested and enter into the acidic stomach.
How does the human body protect itself from microbes?
One way the body protects itself against microbes is with the cell membrane. The cell membrane is like a body guard, it lets certain cells, and virus's in. Another way the body can protect itself is with the white blood cell. The white blood cell defends the body against microbes.
