Essay on Immune System

What is HIV HIV , stands for human immunodeficiency virus, it is a virus that attacks the immune system, the immune system protects the body against infection and illness .If the body does not have a strong immune system, It may not be able fight off disease. The virus and the infection it causes are termed HIV. White blood cells are the part of the immune system that is important as far as fighting off infection. When a person catches HIV it infects and destroys certain white blood cells called

Ebola, and Influenza. So that’s why we use vaccines. All of your vaccines are used as an agent that will build up our immune systems to fight off something that is causing us to become ill. Vaccines improve economic growth, life expectancy, protect people from spreading or acquiring the disease, and vaccines can save a ton of lives. To start off, vaccines trigger our immune systems to be able to build up our immunity to fight off a particular germ that is infecting us. An article I found states that

The organs that make up the lymphatic and immune system are the tonsils, spleen, thymus gland, lymph nodes, and lymphatic vessels. White blood cells (leukocytes), red blood cells (erythrocytes), plasma, and platelets (thrombocytes) make up the blood. Lymphocytes are leukocytes (white blood cells) that help the body fight off diseases. Two types of lymphocytes are B cells and T cells. Lymphocytes recognize antigens, or foreign substances/matter, in the body. Lymphocytes are a classification of agranulocytes

we can do as individuals to strengthen out immune system. I on one hand thinks that there are things that we can do to maintain a healthy lifestyle. According to the website reference below there are ways to adopt a healthy immune system are: balanced diet, exercise regularly to control your blood pressure, drink alcohol in moderation, and getting adequate sleep are all contributors for maintaining a healthy lifestyle, and to keep our immune systems strong. Low levels of stress are also good

amount of the allergen can cause symptoms such as urticaria, angioedema, eczema, nausea, vomiting, and wheezing (Husain & Schwartz, 2013). These reactions primarily consist of the interaction between the proteins found in nuts and the digestive and immune systems (White et al., 2015). While there is extensive research taking place in the prevention and treatment of peanut and TN allergies, the only current management is the strict avoidance of nut products (Wainstein &

In this essay the link between the two different parts of the immune system should be explained. The immune system consists of the innate immune system on the one hand and the adaptive immune system on the other. The innate system reacts fast and protects the body through barriers or special cells, but the specificity of this system is very low. Contrary to the innate system acts the adaptive system. It is needed if the innate system fails and therefore takes more time to get activated, but its specificity

can be answered by learning about one of the most important systems in your body, the immune system. Right now your immune system is at work. Think about it, millions of cells right now are at work inside you. It’s a complex system constantly on that keeps you healthy and at your fullest. This system is made of many organs, cell, tissues and other structures (that work very precisely with each other). Before you learn how the system works, you need to know how about what it defends against.

The Immune System The immune system is a network of organs that contain cells which recognize foreign substances and destroys them. All living organisms are exposed to harmful substances and most can protect themselves in several ways, either with physical barriers or chemicals that repel and kill them. It protects vertebrates against viruses, bacteria, fungi and other parasites. These viruses are called pathogens. The immune system is known to help in the fight against

vertebrate immune system is composed of a constellation of diverse immune cell types, each with an exquisite ability to protect the host from infectious agents, cancers, and other immunopathologies. Central to the success of this elegant complex system is the arm of adaptive immunity, dominated by the effects of T-lymphocytes and B-lymphocytes. In terms of evolutionary history, an immunological “big bang” resulted in the adoption of T/B lymphocyte receptors as dominant anti-pathogen defense system by the

side effects and have controversial issues such as autism, there is no evidence for the issue; therefore vaccines are very important because it can prevent diseases from occurring and in some cases, death. Vaccines have a huge influence on the immune system, in a positive way, because they help prevent people from getting diseases. Vaccines are very beneficial because people are required to get them for many things including travelling, going to college, newer vaccines are being developed, or some
