because the classical pathway can be triggered directly by a pathogen or indirectly by an antigen binding to a pathogen causing generating of active components with various effector functions. 2.5) In a healthy person hydrolysis of the thioester bond in C3 will be regulated by complement control proteins that regulate complement cascade at different points to protect host cell while allowing complement activation to proceed on the pathogen surfaces.

Stress‚ physical and mental abuse‚ diet‚ exposure to toxins‚ pathogens‚ radiation‚ and chemicals found in almost all personal care products and household cleaners are possible causes of a large segment of non-hereditary disease.

Skin secretions are acidic and contain chemicals that make skin inhospitable for pathogens. Ex: lysozyme‚ can digest cell walls of certain bacteria. 4. The mucus membranes not only provide a barrier‚ but they also produce a variety of protective chemicals. For example‚ the stomach secretes digestive enzymes and has a very low pH. The respiratory and digestive tracts are lined with sticky mucous that traps pathogens. 5. Once the surface barrier has been broken‚ the second line of defense‚ the innate

diseases emerge from domesticated animals that act as carriers. Additionally‚ the warmer climate during the Neolithic period provided many bacteria and pathogens a desirable environment to grow. Agriculture’s role in the transmission of diseases includes changing the transmission ecology of existing pathogens‚ increasing the success of pre-existing pathogen vectors‚ and increased carriers of diseases.(Pearce-Duvet‚ 2006) The increases in susceptibility to diseases can also be accredited to the lack of

How does the immune system react to pathogens? It fights off the pathogen by Leukocytes also known as white blood cells. When a pathogen enters the body the immune system becomes alert to it and sends out sends out the Phagocytes (a type of Leukocytes) which engulf the pathogens. If the body has a weak immune system‚ the pathogens eventually overtake the body which can result in a disease. How do the different pieces of the immune system work together? The bone marrow‚ the lymph nodes‚ the spleen
