the third line of defence work as a Primary Responce and a Secondary Responce the Primary Responce occurs when first a pathagen enter the body and secondly lymphocytes (b-cell) produce antibodies and finally antibodies have a speific shape which bind to antigens on surface of pathagen and then the dead pathagen is digested is eaten by phagocytes The Second Responce is the vaccination that contain live pathagen treated to make them harmless and it contain harmless fragment of the pathagen and dead phagen or toxins produced by pathagen and while vaccine is given we will gel active immunity because that vaccine will produce antibodies for ever
Types of cells involved in the immune system:
Each type of virus, bacteria, or other foreign body has molecular markers which make it unique
Thus, immunological specificity and memory involve three events:
(1) Recognition of a specific invader
(2) Repeated cell divisions that form huge lymphocyte populations
(3) Differentiation into subpopulations of effector and memory cells
Antigen-presenting cell - a macrophage which digests a foreign cell, but leaves the antigens intact. It then binds these antigens to MHC molecules on its cell membrane. Theantigen-MHC complexes are noticed by certain lymphocytes (recognition) which promotes cell division (repeated cell divisions)
Tetiary line of defense are your antibodies. The first line of defense is skin, the second line of defense is white blood cells. If the pathogen has passed 1st and 2nd line of defense, your third line of defense comes in to play. Tertiary line of defense includes acquired and innate immunity.
your but smells take a shower caca man or girl
1- the immune systems helps fight off diseases 2-your skin is the first line of defense for your immune system. hope that helps!:)
wwe is the thing in the world No sorry it is actualy the immune system
The first line of defense includes the skin, breathing passage, mouth and stomach.
Your body's third line of defense is the specific defenses, these defenses are called the immune response.
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
Your body's third line of defense is specific defenses, such as the immune response.
skin and mucous membranes first line of defense second line-leukocytes and macrophages, inflammation and fever third is immune system
The third line of defence against pathogens is called the Specific Immune Responce
The immune system's third line of defense is called specific resistance or acquired immunity. The system depends on antigens which are mostly proteins which function as a producer of the immune response.
Yes adenoids are part of immune system. It 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 but cheeks are the third defence against invading pathogens. If the skin or white blood cells have not later killed these systems. While you sleep your but cheeks got into your body searching for the pathogen once it is found the but cheeks squeeze so that is a sorbed and it is out of your system. if it is a serious disease the but cheeks start shutting inside your body so you eventually poo out of your mouth.
In the immune system, the first line of defense are mechanical and physical barriers, such as the skin and the cornea of the eye. The main line of defense, meanwhile, are the innate immunity and acquired immunity of an organism.
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
