There are some diseases‚ such as hepatitis B‚ hepatitis C‚ human immunodeficiency virus (HIV)‚ and acquired immune deficiency syndrome (AIDS). Characteristics of a chronic disease‚ examining the relationship between a healthy nutritional diet‚ and cardiovascular disease‚ the effects of chronic‚ and infectious diseases‚ how exercise affects the immune system‚ and consumer awareness are the focus of this paper.

Premium Medicine Cancer Immune system
is a type of cancer that begins within immune system cells called lymphocytes. Similar to other cancers‚ lymphoma occurs when lymphocytes are uncontrollably growing and multiplying. These lymphocytes are white blood cells that move throughout the body with the help of a fluid called lymph. There they are transported by a network of different vessels that make up the lymphatic system‚ which is a part of the immune system. The main job of the lymphatic system is to fight off infections or anything

AIDS (acquired immunodeficiency syndrome) is caused by HIV (human immunodeficiency virus). HIV is transmitted usually through unprotected sex with someone who is already infected‚ but it can also be transmitted through infected blood. The immune system is greatly affected by the disease. Once it enters the body‚ the virus recognizes a protein on helper T-cells‚ called CD4 (Cluster of Differentiation Antigen No. 4)‚ and it attaches onto that receptor to take over the CD4 cell. The result is a virus

Digestive System Digestive System: It is a system that involves all the organs that aid in digestion. Digestion starts in the mouth. The human body receives nutrients via the digestive system. Obesity Obesity: It’s a condition where the affected person is obese or overweight. Obesity can cause other health problems. Circulatory System Circulatory System: It is a system that circulates lymph and blood. The circulatory system provides the body with lymph that aids the immune system. Hypertension

HIV and AIDS Have you ever wondered what HIV or AIDS are? HIV stands for human immunodeficiency virus. It causes AIDS which stands for acquired immune deficiency. These viruses attacks the immune system and can cause you to die because it attacks your helper T cells. There are no cures‚ but you can take medication to help with the symptoms. AIDS and HIV are STD. When one person has AIDS and you have contact with that person they can transmit that disease to you. Another way you can develop AIDS

Immunity Objectives 1) Describe the cell functions of the Immune System: Lymphocytes- small white blood cells that are responsible for much of the work of the immune system. Three types: Natural Killer Cells-NK cells provide rapid responses to virally infected cells and respond to tumor formation. NK cells are unique bc they have the ability to recognize stressed cells in the absence of antibodies and MHC‚ allowing for a much faster immune reaction. Trigger phagocytes to the site.

Graves’ disease is an immune system disorder that causes an overproduction of thyroid hormones called hyperthyroidism. Although there are many diseases that cause hyperthyroidism‚ Graves’ disease is the number one cause. It is named after Robert Graves‚ an Irish physician‚ described this form of hyperthyroidism about 150 years ago. Graves’ disease is caused by a process in the body’s immune system‚ that normally protects the body from bacteria and viruses. The immune system destroys the bacteria

Which WBCs are responsible for the immune response against pathogens? How do they functions? White blood cells or leukocytes are vital cells of the immune system protecting the human body against infections‚ bacteria‚ microbes‚ viruses and pathogens. These cells are produced in the stem of the bone marrow and
