Leukocytes: Second Line Of Defense In The Immune System

Improved Essays
Leukocytes are white blood cells that not only fight disease, but removes pathogens from the body. Leukocytes are the second line of defense in the immune system’s characteristics. Higher levels of a white blood cell counts are also referred to as leukocytosis and can be indicative of infection or disease. Lower levels however, can be indicative of leukopenia which can weaken the immune system and cause infection and disease to overpower the body. Leukemia is a disorder that affects not only bone marrow but also leukocytes due to the fact that they are connected to the same area of the body. (Zimmermann, 2016)
Without some line of defense in our bodies we become susceptible to every that bacteria, virus, disease or parasite and will inevitably

    Echinacea works by stimulating the immune system. Whereby antibiotics destroy both good and harmful bacteria Echinacea enables your body to deal with infections and viruses as they happen. Studies show that Echinacea stimulates phagocytosis, a process where white blood cells travel around the body hunting and attacking harmful micro organisms releasing chemicals and digesting them. White blood cells are a major component of the body's inbuilt quick response immune system.…

    Leukocytes function is to protect the body from infectious diseases. Erythrocytes function is delivering oxygen to organs and cells via the bloods circulatory system. Platelets function is to clot blood so that it prevents any blood loss. Firstly the main protein is called hemoglobin, functioning to transport oxygen to the entire body including every tissue from the lungs, then transporting c02 back to the lungs. Furthermore fibrinogen is a protein in the matrix which works with the platelets to make blood clots and globulin is another protein in the matrix which delivers antibodies.…

    The immune system is made up of different parts that are constantly protecting the body from disease-causing microorganisms known as pathogens. By keeping out these infectious pathogens out of the body or destroying the pathogens that do enter the body, the immune system is a complex network of cells and organs that protect the body from infection. The primary immune response is the response that is activated when the body is first exposed to an antigen, resulting in the activation of lymphocytes. If the human body is encounters the same antigen again, the secondary immune response is activated.…

    The lymphatic system is a key system made up of tissues and organs that help maintain your immune system and clean the body of unwanted materials and toxins. In other words, the lymphatic system is the main line of defence when you become ill. in the case of some illnesses, the lymphatic system can be damaged and cause defects in your body that can have lifelong effects on your standard of living. Two diseases in particular are caused by a malfunction in the lymphatic system and they are called Hodgkin’s Lymphoma, a disease caused by mutation in B lymphocytes and Elephantiasis, caused by a parasitic worm carried and transferred by mosquitos.…

    Although I agree with you on the inflammatory response being vital for protection, I have to disagree that it is the best protection of the body. Physical and biochemical barriers protect the body without producing harmful effects. Inflammation is activated after the first protection barrier has been penetrated and begins the destructive cascade. As you said inflammation can be, “activated by virtually any injury”, inflammation can protect the body, but it can also preserve an injury that has not occurred and “cause more harm to the body in cases of allergy, autoimmunity, and during infections in tissues with poor regenerative capacity, such as the heart” (Boundless, 2016, para. 1).…

    The body’s natural protection mechanism against infection from pathogen is not as effective as it can be, especially for individuals that have compromised immune response. The body’s immune response system has an essential resistance and adaptive immunity as its first line of defense. When the front-line defense (innate) immunity fails to protect the body against microbial pathogens the second line of defense (adaptive) which is more specific is activated (H. ,2012, September 11). The innate immunity contains different cell forms that generates a barrier stopping the pathogen from entering the body. If the pathogen successfully enters the body it then allows phagocytic cells to activate within the site of the infection destroying the pathogen.…
