Complement system is an important factor that ‘complements’ the immune system. Do you agree with this statement? Explain.

I agreed with that statement. By the name, we know already the function of complement system. It is to ‘complement’ the antibacterial activity of antibody. To be more specific, complement system is plasma proteins that is made up in a large number that can react with one another to opsonize all the pathogens and induce a series of inflammatory responses that can helps to fight the infections. Complement system consists of 20 different serum proteins that are produced by variety of cells such as liver cells, macrophages and gut epithelial cells. The overall function of complement system is to control on the inflammatory.

There is a way to activate the complement system. The complement activation can be done by a reaction where one component acts enzymatically on the next component to generate an enzyme that can be mediated to the next step.

The activation of complement system can helps the immune system by opsonisation of microorganisms, recruitment and activation of phagocytes to the sites of infection. It also participated in regulation of antibody responses and aid in clearance of immune complexes and damaged cells.

There are three biochemical pathways that can be activated on pathogens surfaces by the complement system. Those are, classical complement pathway, alternative complement pathway and lectin pathway. By this complement activation system, it really helps the immune system in the body and very

    1. The pediatrician described Jason’s pharynx, uvula, and tonsils as swollen and red. What are the four cardinal signs of inflammation, and how does each relate to changes in the blood vessels at a site of inflammation? Heat, redness, swelling and pain and according to the book loss of movement in in a joint. The damaged or in this case the infected area is inundated with phagocytes (neutrophils and macrophages) and what is called complement is activated and if the classical pathway is used that means the antibodies are produced and complement proteinsC1,2 and 4 are activated and in turn activated C3. The alternative pathway is when C3 and factors B,D, and P interact on the surface of the pathogen and C3 is again turned on and at this point it is split into C3a and C3b. When C3b binds to the pathogen the inflammation we all know and love becomes present. Fever is a response by the neurons in the hypothalamus in response to pyrogens which are secreted by macrophages and leukocytes. Pain is caused by the swelling of the area in question as the nerves are being pressed and toxins affecting the area.…

    The Immune system is one of the most important parts of the human body. Its role is to protect us from outside dangers such as pathogens and disease and to keep the body healthy. The immune system protects the body from disease by having a complex system of organs and cells to keep the body safe. The first barrier of the immune system and of the body is the skin which keeps out pathogens from entering the body, but if there is a cut in the body, the skin can no longer defend against the pathogen, so next comes inflammation which helps to limit the spread of the disease by causing swelling and a large amount of white blood cells to go to the injured parts of the body. Another really important…

    Complement Cascade consisted of an invading cell where it was tagged by antibodies and complement activated. Dr. Brown measured the complement pathway through the bacteria killing ability using a serum that was mixed with the bacteria which in turn allowed to measure the percentage of bacteria killed. Hemolytic-complement activity was also measured through serum mixing with SRBC and anti-SRBC antibodies which allowed for the percentage of cells lysed to be able to be recorded. Dr. Brown aimed to see if population density had an effect on the parasite load, and she concluded it does. Additionally, she came to the conclusion that not just density has an effect, but age as well.…
