    The immune system utilizes its biological responses to protect the body from infection and disease. It's critical mechanisms allow for the rapid sensing and elimination of microbes that can harm your body. When a virus invades your body the immune system enforces a complex process to remove it. Your body carries out this process by identifying the virus, activating the immune system, and by restraining and eliminating the virus. When dealing with intruders, the body recruits relies on the adaptive

    The immune system is divided into two categories, the innate and the adaptive immune system. Each system is a part of the organism, and either one does not necessarily take over more than the other. The innate immune system gets its name and function from being with us from the beginning of our lives (“Introduction to Immunology Tutorial…”, 2000). What I mean by this is that there are certain barriers that immediately know when a foreign invader has entered the body, and the body will respond quickly

    How The Immune System is Affected by the Digestive System Our body consists of 90% of bacteria. That means that for every cell that we have in our body, we have 9 bacterial cells living along with it. Granted that most of the bacteria live inside the intestinal tract, but without a proper immune system keeping the digestive system in check, we would not be properly digesting food or have healthy bodies. When the number of bacteria living inside the body is balanced, the immune system is also balanced

    The immune system is a highly evolved and complex defence system, armed against millions of potential pathogens that may cause infection at any point. Pattern recognition receptors, known as PRRs, are displayed by the cells of the innate immune system, such as macrophages and dendritic cells, and recognise pathogen associated molecular patterns or PAMPs. PAMPs are evolutionary conserved structural similarities found in many pathogens but not in the host’s own cells allowing the innate immune system

    physiological processes in the human body, including immune system function. The immune system can be divided into two main categories: innate immunity and adaptive immunity1. The adaptive immune system is responsible for fighting against specific pathogens or antigens and a memory component is involved. Additionally, its response is longer than an innate immune response, upon its first exposure to said antigen or pathogen. In contrast, the innate immune system responds much faster, however there is no memory

    human body is not without a defense system. Otherwise the environment would have severely harmed and destroyed it. The environment is full with harmful agents such as bacteria, viruses, fungi, parasitic organisms. Tumor cells and other factors are also able to affect the body negatively. To protect against, prevent or limit damages from those agents, the body uses the help of what is known as the immune system. What is the immune system?

    The immune system is a fascinating structure it defends the body against foreign invaders like bacteria, viruses and parasites. There are two primary forms that make up the immune system they are, innate and adaptive systems. Both the innate and adaptive system plays a large role in the immune system. The innate is the primary system to defend against foreign materials and the adaptive is the secondary system that responds to specific issues. The difference between the innate and the adaptive

    Our body’s defense system is a complex network of organs containing cells that recognize infections and diseases in the body and destroy them. When functioning properly, the immune system can distinguish between healthy tissue and critical viruses and bacteria. This system contains the thymus, white blood cells, antibodies, epidermis, cilia, mucus, and saliva. The thymus is a small organ where the white blood cells mature. THe white blood cells divide into two groups. On which creates antibodies
