Immune System Of The Respiratory System

- The lungs are the main organs of the respiratory system. Their function is to regulate gas exchange. They are located in the thorax. They are connected to the trachea which conducts inhaled air through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (called bronchioles). The bronchioles eventually end in small air sacs called alveoli. It is in alveoli that occurs the gas exchange. Lungs are in contact with airway microorganisms and elements like tobacco....   [tags: Immune system, Innate immune system]

The Adaptive Immune System Function

- Sleep is a necessary phenomenon that impacts many 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 component involved....   [tags: Immune system, Innate immune system]

The Immune System Of Antibodies And Antigens

- As this experiment deals with antibodies and antigens, it is important to understand the immune system. The immune system is generally composed of two subsystems: the innate or nonspecific immunity is the kind that every person is born with. Innate immunity is the first line of defense and includes the skin, mucousal membranes, dendritic cells, phagocytic cells, mast cells, natural killer cells, basophils neutrophils, and eosinophils. Adaptive or acquired immunity is immunity that is gained overtime and is highly specific towards what it targets....   [tags: Immune system, Antibody, Innate immune system]

The Immune System And Complex Defence System

- 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 to distinguish between self and non self and to react to the pathogens immediately (Mogensen, 2009)....   [tags: Immune system, Innate immune system]

Gene Therapy And The Immune System

- Gene therapy involves using a vector to deliver genes to a targeted cell, tissue, or organ. Adenovirus is one of the many viral vectors in gene therapy to deliver genes to targeted cells. When gene therapy was first introduced by Dr. Stephanie Cherqui, immune cells were removed from the body and infected with adenovirus containing the functional gene that cystinosis patients lacked. In contrast to treating genetic disease that affects all cells with gene therapy, I am interested in expanding on the topic of selectively delivering genes to cells that has acquired mutations in tumor suppressing genes and have undergone carcinogenesis....   [tags: Immune system, Cancer, Protein]

Pathogen And The Innate Immune System

- Before addressing how pathogen recognition works, it is necessary to define the terms ‘pathogen’ and ‘innate immune response’. Pathogens are defined as anything that can cause disease. The innate immune system is the evolutionary conserved system that acts as the primary barrier to infectious agents. In other words, it is the host’s first line of defence. It acts immediately and uses protective mechanisms that involves phagocytes. PATHOGEN-ASSOCIATED MOLECULAR PATTERNS (PAMPs) AND PATTERN RECOGNITION RECEPTORS (PRRs) Hosts can recognise non-self and dangerous antigens because of two reasons....   [tags: Immune system, Microbiology, Bacteria]

The Major Function Of The Immune System

- . The major function of the immune system is to protect the tissues of its host from harmful microbes or other foreign organisms. However, certain individuals suffer from what are known as autoimmune disorders, which result in the immune system mistakenly attacking its own tissues.

Additionally, the human body natural defense system has a hard time fighting off the HIV virus, because the immune system becomes weak after exposure to the HIV virus.

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.

The Effects Of Hiv / Aids On The Immune System

- The Effect of HIV/AIDS On The Immune System The bodies immune response is built upon humoral immunity by use of B Lymphocytes, and cell-mediated immunity by T lymphocytes. The cell-mediated immunity is necessary in defense from viruses, such as HIV. Helper T cells, one of the T-lymphocytes, are especially essential to the immune system, as they regulate and control the immune system. Under normal circumstances, helper T cells make contact with a virus via CD4 proteins found on the surface of the cells, leading to a release of cytokines, which “enhance the actions of macrophages and NK cells” (Stanfield 2013)....   [tags: AIDS, Immune system, T helper cell, HIV]

It reacts by triggering Toll-like receptors (TLRs) who then fasten to pathogen-associated molecular patterns (PAMPs) (Joanne M. Willey, 2014). The first line of defense in the innate immune system contains the skin and mucous membranes, along with normal microbiota (Joanne M. Willey, 2014).

The Immune System

- The Immune System The immune system is a group of cells, molecules, and tissues that help defend the body against diseases and other harmful invaders. The immune system provides protection against a variety of potentially damaging substances that can invade the body. These substances include disease-causing organisms, such as bacteria, fungi, parasites, and viruses. The body's ability to resist these invaders is called immunity. A key feature of the immune system is its ability to destroy foreign invaders while leaving the body's own healthy tissues alone....   [tags: essays research papers]

The Immune System

- The Immune System The Immune System is a group of cells, molecules, and organs that act together to defend against disease. The body depends on the immune system to seek and destroy bacteria or viruses that could cause harm. There are two types of immunity: innate and adaptive. Innate is the body's first line of a defense against the disease. The innate immunity helped by barriers such as skin, tears, mucus, saliva, and infection. But the innate can't usually prevent disease completely. After the disease has passed through this it has a specific immunity which is known as adaptive immunity....   [tags: Papers]
