no because it is in the body
Barriers, The Inflammation Process, and Antibodies.
External defenses - Includes skin and mucous membranes. Internal defenses - Includes phagocytic cells, inflammatory responses, and antimicrobial proteins.
First of all, you might want to spell DEFENSE correctly.
The first line of defense is the skin. It tries to keep germs out of the body. If germs get inside the body, then Leucocytes (White blood cells) and antibodies attack the invaders and try to destroy them.
The body has three main lines of defense against pathogens. They are as follows:First line of defense: Skin, Mucous membranes, and Secretions of skin and mucous membranesSecond line of defense: Phagocytic white blood cells, Antimicrobial proteins, and the Inflammatory responseThird line of defense: Lymphocytes, and Antibodies
Earl's-defense is a system of fortifications for protection.

when the first and the second lines of defense have already been overcome.
Yes it is a good line of defense.
Trenches were the lines of defense dug into the earth, particularly during WWI.
1) Physical (skin and mucous membranes) and chemical barriers that prevent entry by pathogens, 2) Nonspecific defensive cells (phagocytes, eosinophils,white blood cells, and natural killer cells) and proteins (interferons and complement system), inflammation and fever, and 3) The immune system that has specific targets and memory.(lymphatic system-recognition of foreign cells) The Human Body's 3 lines of defense 1.) Integumentary System-skin and accessory organs such as hair, nails, sweat glands, and oil glands 2.) Circulatory System-heart,arteries,veins,capillaries, and blood 3.) Lyphatic and Immune Systems-Thymus, bone marrow, spleen, tonsils, lymph nodes, lymph capillaries, lymph vessels, lymphocytes, and lymph
