How can you prevent cancer? Research shows that there are ways to prevent cancer. Avoiding smoking cigarettes and exposure to smoke will decrease the chances of getting lung cancer. Fruits‚ vegetables and a well balanced diet are important to keep healthy and will help repair damaged cells. Colleen Huber stated‚ “All foods should be whole‚ not processed because of all the synthetic chemicals in packaged food.” (Huber) Keeping track of your personal and family medical history will help the risk factor

GENERAL PRINCIPLES OF THE IMMUNE SYSTEM Introduction Constituents of Immune ? system Types of immune response Introduction The immune system is: The body defense mechanism an interacting set of organs‚ specialized cells and proteins designed to identify and destroy foreign invader Ministry of defence of the human body The immune system must be able to: differentiate between normal component of the body (“self”) and material that is not native to the body “nonself” A highly specialized receptors

The innate immune system is referred to as the first line in host defense against invading pathogens and preserve host integrity [1]. Of them the innate immune cells have sensors such as macrophages and dendritic cells (DCs) detect molecular components of foreign microorgan¬isms known as pathogen-associated molecule patterns (PAMPs) through PRRs. Its highly developed ability to recognize microbial patterns and host derived danger signals relies on so-called PRRs‚ especially on the TLRs‚ RLRs and

Research into the effects of stress on the immune system There have been various studies into the effects of stress on the immune system. Kiecolt-Glaser researches this by looking at how quickly wounds heal. She used 13 women aged 47-81 who cared for Alzheimer’s and Dementia sufferers. They had naturally occurring high stress levels‚ and this is why she chose them. The women were matched with volunteers for maximum similarity (the matched pairs design). Kiecolt-Glaser tested all the women’s

Chapter 20: The Immune System The immune system has two intrinsic systems: 1. Innate (nonspecific) defense system 2. Adaptive (specific) defense system The immune system is a functional system rather than structural; there are no specific immune system organs Pathogen: a disease-causing agent; anything foreign in our body that causes disease Three lines of defense: 1st: external barriers 2nd: several non-specific defense mechanisms 3rd: immunity‚ specific resistance to disease

The role of the immune system in Parkinson disease Last semester‚ I took a class with Professor Jia Shi‚ Pathophysiology of Disease‚ and we covered the role of the immune system in many diseases and in our body. This phenomenal system‚ the immune system‚ defends us when we are awake and asleep. It works around the clock without rest to keep all the invaders away like bacteria and viruses. Scientifically at the molecular level‚ there are proteins called Cytokines that are produced by

swellings on mucous membranes. The disease itself is caused a bacillus called Mycobacterium tuberculosis and mainly affects the lungs‚ however the central nervous system‚ the lymphatic system‚ the circulatory system‚ the genitourinary system‚ bones‚ joints and even the skin also has a chance of being affected. Our body’s immune system responds to this infectious disease by having a group of white blood cells to try to identify the disease causing bacterium and destroy it. Another way our body responds

1. The mercenary camp was in the Motaba River Valley of Zaire was bombed to stop the virus from spreading. 2. No I would have removed all the people and disinfected all of them so the virus would stay in the forest and nobody would die. 3. Sam Daniels and his crew were sent out to the Motaba Valley because there was a level 4 virus. 4. The conditions in the Motaba valley were sad‚ smoky‚ poor and there were dead people everywhere. 5. The symptoms of the mystery disease at Motaba Valley

hypersensitive disorder of immune system. An allergy is a type of reaction of the immune system. Substances that often cause allergic reactions are pollen‚ dust mites‚ mold spores‚ pet dander‚ food‚ insect stings and medicines. The body’s defense mechanism works over time to react against these foreign particles (known as allergens)‚ which may pose danger to normal functioning of the human system. People with allergies have an exaggerated response of the immune system. However‚ in most allergic
