What is innate immunity? discuss the barriers associated with innate immunity.

Innate immunity is a nonspecific defense mechanisms that play its role as soon as an antigen appear in the body (it is relatively rapid but nonspecific and because of that it is not always effective)

Explanation:

The barries of innate immunity are:

Skin: At Epidermal surface, its protective aspect are keratinized cells that lives on the surface, known as Langerhans cells.

Skin sweat or secretions: Their specific defense is sweat glands and sebaceous glands, and their protective aspect is low ph and washing action.

Mucosal surfaces: they are at the mucosal epithelium, and their protect aspects are nonkeratinized epithelial cells.

Oral cavity: They defend salivary glands through Lysozyme

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
