macrophage
1- skin 2- WBCs present in the blood 3- even fever and inflammations can be considered as defences 4- production of immunoglobulins 5- HCL acid produced by the stomach and there are too many others defences that can be studied in each organ or biological system specifically
Lysozymes
Macrophages, natural killer cells, and complement proteins participate in the body's second line of defense. These components help to identify and eliminate pathogens that have breached the first line of defense, which includes physical and chemical barriers like the skin and mucous membranes.
An animal must defend itself from foreign intruders, such as bacteria, viruses and other pathogens. It must also deal with abnormal cells that periodically appear in the body.Two cooperative defense systems that counter these threats have evolved. * Non specific resistance * the immune system ans specific defense In the non specific system the body does not distinguish one infectious agent from another. This includes two lines of defense. # external: consists of epithelial tissue eg skin, mucous membranes, # Internal: It is triggered by chemical signals and employs antimicrobial proteins and phagocytic cells that indiscriminately attack any invader that penetrates the bodys outer barriers. The immune system responds specifically to the particular type of invader. This includes production of specific defense proteins called antibodies.It also involves the participation of several different types of cells that are decendents of white blood cells called lymphocytes. The immune sytem constitutes a third line of defense, which comes into play simmultaneously with the second.
A lack of T-cells results in a weakened immune system, leading to a condition called Severe Combined Immunodeficiency (SCID). This condition makes individuals highly susceptible to infections due to the inability to mount an effective immune response against pathogens. Without functioning T-cells, the body is unable to coordinate a proper immune defense, making even minor infections potentially life-threatening.
its killer T cells
the integumentary system is the skin and the bodys first line of defense.
The tonsils are apart of the lymphatic system. They aid in the bodys ability to fight germs.
Neutrophils
Cardiovascular
axons neurons , cells help protect the bodys defense system against infection ..auto-immune defiency ...also oxygen
This is your bodys natural defense to protect the eyes. It is a reflex.
Circulatory system
yes
I believe the bodies transportion system is the cardiovascular system :)
