when it gets past the first line (the skin)
The skin is the "first line of defense".
yes
The first line of defense includes the skin, breathing passage, mouth and stomach.
The Epidermis .
skin and mucous membranes first line of defense second line-leukocytes and macrophages, inflammation and fever third is immune system
when it gets past the first line (the skin)
white blood cells
when the first and the second lines of defense have already been overcome.
Your skin,sweat,mucus,and tears is the first line of defense of your immune system. it is the original protector from bacteria and viruses
the body's second line of defense against pathogens is the B cells.
The Second Line of defense is mainly called the Inflammatory Response. Some may say the immune response is the second layer too. The Second Line of Defense also includes leukocytes such as macrophages.
The skin is the "first line of defense".
there are actually three categories of defenses in the body, namely: first line of defense, second line of defense and the third line of defense.first line of defense is our skin. the vaccine you're talking about falls under the second line of defense because it involves the immune system wherein these vaccines were introduced into the body,nonetheless, the cells on our body creates/secretes chemicals that serve as defense mechanism; and the third line of defense is the use of medications or chemicals prescribed by the doctors.
The body uses the first, second and third line of defense to fight the measles virus.
The first line of defense includes the skin, breathing passage, mouth and stomach.
The first and second lines of defense are both components of innate immunity, that is defenses that are present at birth. The job of the first line of defense is to keep microbes out of the body. They include the skin, mucous membranes and their secretions and the normal flora. The second line of defense is activated once the microbe gets into the body. The second line of defense includes white blood cells (which "eat" invading microbes), inflammation (which is used to isolate the microbes and facilitate tissue repair), fever (which inhibits replication of microbes and enhances WBC performance), and antimicrobial substances.
