skin and mucous membranes first line of defense second line-leukocytes and macrophages, inflammation and fever third is immune system
its something alright
The third line of defence against pathogens is called the Specific Immune Responce
when the first and the second lines of defense have already been overcome.
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.
Antibodies are produced by B lymphocytes as the third line of defense to provide humoral immunity.
Well, you first get infected from a scratch or bite, then the infection spreads into the bloodstream, getting by the first line of defence. The second line of defence, would be the white blood cells. They try overcome or "swallow" the infection. the third line of defense, is the anitgens. If all else fails, your f*cked.
I would have to say the Immune System is the third line of defense in the human body- Acquired Immunity B and T cells Lymphocytes. 1. First line of defense- Physical barriers like the skin and mucus membranes 2. Second line of defense- Phagocyte cells: These are cells that gooble up waste products Source: Taught Anatomy and Physiology to nursing students for over 2 years- My head RN in NJ Hope this helps.
The first line of defense is physical barriers like skin and mucous membranes, which prevent pathogens from entering the body. The second line of defense includes immune cells like neutrophils and macrophages, which attack pathogens that breach the first line. The third line of defense is the adaptive immune response, involving T and B cells that target specific pathogens and create immunological memory.
The integumentary system is one of the first lines of defense against infection. It provides a physical and chemical barrier against the entry of pathogens.
