What Is The Body S Second Line Of Defense

This is the immune system.

The second line of defense is nonspecific resistance which also is considered a function of innate immunity. Nonspecific innate response pathogens that successfully cross the physical barriers are next encountered by the second line of defense.

A type of white blood cells called phagocytes are released. The second line of defence is also a non specific response i e. It is non specific cannot differentiate between specific microorganisms it is non adaptive produces the same response every time in other words it does not possess memory. The second line of defence is a group of cells tissues and organs that work together to protect the body.

The body s second line of defense against pathogens is the b cells. The cells involved are white blood cells leukocytes which seek out and destroy disease causing organisms or substances. It is a 3 pronged attack on any microbes that have survived the first line of defence. Phagocytes are leucocytes white blood cells that are made in the bone marrow and circulate through the circulatory and lymphatic systems however can also leave and travel to the site of pathogen entry.

Second line of defense this line of defense is activated when microbes manage to get inside the body. The response is the same for any pathogen. For example macrophages are cells derived from monocytes a type of white blood cell. What is the second line of defense against disease.
