Physiological Dimension Immune/Defense Mechanisms Age specific variations of growth and development. For children ages three to five years immunization status is necessary. The Nursing care of Infants and children, has recommendations for routine immunizations. Preschoolers should have already been administered their Hepatitis B, Hepatitis A, Measles, Mumps, Haemophilus influenza Type B, pneumococcal disease, and meningococcal disease. (Hockenberry, Wilson, 2015, p.202-205) Three to five year olds

The immune system is responsible for protecting us from external pathogenic attack. Humans are born with an innate immune system where the white blood cells help to fight against disease causing agents. Overtime they acquire adaptive immunity. A genetic condition where mutation disrupts the innate immune system is known as Severe combined immune deficiency. It is a X-linked primary genetically inherited condition where the newborn child has a non working immune system and is susceptible to all diseases

The immune system is a crucial and essential defense mechanism in the human body as it allows the differentiation of cells that are self from cells that are non-self (reviewed by Spiering, 2015). The immune system is subdivided into two major categories: the innate immune system and the adaptive immune system (reviewed by Spiering, 2015). The innate immune system, also known as the non-specific immune system, is composed of cells and structures that are acquired from birth and defend and protect

environment? A parent’s protective instinct to keep their child clean and healthy may backfire when the child gets older. An infant 's immune system is very weak and only gets stronger as it is exposed to more bacteria. Children who grow up in a more controlled, sick free environment are more likely to have more sick days once they start school. Their immune system is not strong enough to handle the new germs in their environment. It sounds strange but the more colds, flu and ear infections a child

The immune system is the body defense mechanism against diseases. Through its different components, the immune system can detect a wide range of microorganisms such as viruses, parasites, bacteria and strange organisms. It has the power and the intelligence to distinguish those microorganisms from the self-healthy tissues; recognize them and eliminate them to protect the body from their harmful effects. However, in some instances, the immune system reacts against self-cells as in autoimmune diseases

the initial phase of an infection, the innate immune system generates a rapid inflammatory response that blocks the growth and dissemination of the infectious agent. This response is followed, in vertebrates, by the development of an acquired immune response in which highly specific B and T cell receptors recognize the pathogen and induce responses that lead to its elimination (Janeway, Jr. et al., 2002). The antigen receptors of the acquired immune system are well characterized. They consist of

Adaptive immune system The adaptive immune system also called acquired immune system, differs from the innate immune system since it is more specific to each type of molecules. Indeed, it relies on T and B lymphocytes that have an antigen specific receptor on their surface. Due to the lack of molecules owning this receptor, the adaptive immune system is much slower than the innate one because it needs more time to identify the antigen of the bacteria. During the inflammatory response, the adaptive

Minneapolis MN The purpose of the immune system is to prevent and minimize infections; this is how the body protects us from microbes that would otherwise make us ill or kill us (Dugdale, 2013). The immune system works by differentiating between our own cells (self-antigens), foreign cells (antigens), and pathogenic microbes (Dugdale, 2013). When our cells discover anything unfamiliar, our immune system works to destroy it(Dug dale, 2013). If the immune system cannot activate to kill foreign

toxins is the major function of the immune system, a task essential to any organism. Composed primarily of individual cells rather than forming into organs, the cells of the immune system spread throughout the body. The immune system is able to distinguish its own molecules from foreign molecules. There a number of key stages involved an immune response; pathogen, recognition, activation and initiation, regulation, and the generation of immunological memory. The immune system of the vertebrate is divided

Introduction The main aim of the immune system is to limit and dispose any harmful waste products as well as evacuating the damaged tissues so that the body can begin healing. The body’s self-protective reaction comprises of variations in the blood stream to take in an increased discharge of fluids from the veins together with an increase of plasma, T-lymphocyte cells, proteins and phagocytes to enter the tissue so as to heal the damaged area as well as fighting off bacteria and viruses. The T and
