Immune system

The job of the immune system is to be a defense mechanism against diseases and any other harmful substance that enters the body. When it is functioning properly the immune system will attack any invaders and neutralize that specific threat. It will also create an encoding of that specific disease or sickness so that the body can never be harmed by that specific one ever again. So essentially the immune system is an ever changing and constantly strengthening tool that is essential in maintaining health in the body. (Mccoy, 2014) The immune system functions primarily by attacking disease makers called pathogens. It does this through the use of Leukocytes. These are white blood cells. These cells are housed around the body and are the attackers…

The Human immune system and Autoimmunity The human immune system is a true strong-hold and defender, which response firmly and swiftly to attacks from foreign invaders. It has the ability to manipulate change in order to optimize the response and quarantine many of the unwanted intrusions. The Human immune system has many purposes. They include, defending the body against infectious microorganisms, such as fungi, bacteria and viruses-by destroying and resisting them. The Human immune system is…

Links between the human immune system, pathogens, antibiotic resistance and mutations are discussed in this report. It is stated that the antibiotic resistance and overuse of vaccine has contributed to the increased incidence of emerging diseases and resistance to their controls and treatments. The human immune system is the protection of the body against potentially damaging foreign bodies and other disease. Pathogens are organisms, including a bacterium, a virus or a fungus and these causes…

The immune system is known for its primary role in protecting the body from bacterial, parasitic, fungal and viral infections. It consists of organs and cells that play important and very specific roles in order to achieve adequate protection. The main components include: Organs • Bone Marrow Produces all the cells of the immune system through a process called hematopoiesis. • Thymus Produces mature T cells through a process called thymic education. • Spleen Its primary role is to filter the…

As a health science major or even someone adequately informed on healthcare knowledge knows which populations are more susceptible to infections. Those populations being children, elderly, and immune deficient or compromised populations. While the immune comprised are just how their title makes them sound, their immune systems do not function properly whether it is due to genetics or simply something they are going through health wise. Children however have not yet had the chance to build up…

The innate immune system is the defense mechanism that is activated immediately or shortly after the body is exposed to invading microorganisms.1 This system is quick in response and does not have a memory, meaning it doesn’t need previous exposure to the foreign microbe’s antigen before it can be activated.2 The adaptive immune system consists of antigen-specific immune responses.2 This system is slow in response because after it is exposed to an antigen, it needs time to process the antigen…

Innate immunity constitutes the first line of defense and is fundamental for the recognition and the initiation of an inflammatory response against microorganism. Maintenance of homeostasis is a primary function of the innate immune system and it is achieved through immune surveillance by pattern recognition receptors (PRRs), such as Toll-like receptors (TLRs) and nucleotide-binding domain leucine-rich repeat containing receptors (NLRs). The PRR’s are predominantly expressed by cells of the…

The immune system The human body without some sort of protection system would not be able to endure the many pathogens than we come in contact with on a daily basis. That is why we have an immune system. What is the immune system and what are its functions? According to stanfordchildrens.org, the immune system is a complex network of cells and organs that protect the body from infections that may enter through what we come in contact with. This may not seem like a big role, but it is…

“The immune system is a network of cells and organs that work together to defend the body against attacks by 'foreign ' invaders. These invaders are primarily germs--tiny infection- causing organisms such as bacteria, viruses, parasites and fungi” (9.1 Mind and Immunity). The job of the immunes system is to keep out and destroy these “foreign invaders”. Organs of the immune system are called lymphoid organs that have lymphocytes (small white cells that are produced in bone marrow and fight…

The interaction between the CNS and the systemic immune system is delicate, being limited by the presence of the blood brain barrier (BBB), which renders the CNS immune homeostasis in a dormant self-tolerant state (1). Selective permeability of the BBB plays a crucial role in regulating the entry of specific molecules into the CNS and excluding most macromolecules from passing into the brain (2, 3). This unique feature of the BBB also prevents leakage of neurotransmitters into the circulation.…
