Diseases Affecting the Immune System Amyotrophic lateral sclerosis, or ALS, is a disease of the nerve cells in the brain and spinal cord that control voluntary muscle movement. The cause of ALS is unknown and also referred to as Lou Gehrig’s disease. The progressive degeneration of the motor neurons in ALS eventually leading to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected.
1) Coronary artery disease occurs when fatty deposits called plaque build up inside the coronary arteries. The coronary arteries wrap around the heart and supply it with blood and oxygen. When plaque builds up, it narrows the arteries and reduces the amount of blood that gets to your heart. This can lead to serious problems, including heart attack. 2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries.
Neutrophils have a multi-lobed, segmented or polymorphonuclear nucleus and so are also called PMNs, polys or segs. Bands are immature neutrophils that are seen in the blood. When a bacterial infection is present, an increase of neutrophils and bands are seen. Eosinophils kill parasites and have a role in allergic reactions. Basophils are not well understood, but they function in allergic reactions.
Dysfunction of the chest wall 3. Dysfunction of the lung parenchyma and 4. Other causes. Decreased respiratory drive Decreased respiratory drive may occur with severe brain injury, large lesions of the brain stem (multiple sclerosis), use of sedative medications, and metabolic disorders such as hypothyroidism. These disorders impair the normal response of chemoreceptors in the brain to normal respiratory stimulation.
Burns <25% TBSA produce primarily local response an >25% TBSA local and systemic response. Skin functional changes such as loss of surface, layers of dermis and epidermis, cause inability to regulate body temperature and body cells necrosis disrupt it metabolic function and damage to peripheral microcirculation. Some cells are destroyed instantly. Others are irreversibly injured. Cellular damage is distributed over a spectrum of injury.
Mechanical obstructions occur as a function of the body itself. Tumors and scar tissue can form from previous surgeries or cancers. Hernias, Crohn's disease, diverticulitis, inflammatory bowel disease and severe constipation can cause the intestine to twist and narrow into a complete obstruction. Blockages can also occur when the intestine creates an intussusception; a telescoping formation. Anyone with a disease of the lower digestive tract is susceptible to the possibility of obstruction of the large bowel.
Collagen is responsible for keeping the organs in place, and the virus destroys and digests such tissues. It also causes blood clots in the bloodstream, so the blood thickens and the blood flow weakens. These clots tend to get stuck in the blood vessels, which in turn causes the red spots on the skin. As the disease progresses, the
It could be chronic and is caused by the narrowing of the coronary artery and limitation of blood supply to part of the muscle. It also could be acute, which is the result from plaque suddenly rupturing. The inner wall of an artery is damaged. Some fatty deposits or plaques made up of cholesterol and other cellular waste products will accumulate at a site of injury in a process called atherosclerosis, the hardening of arteries. If the surface of the plaques break or rupture, blood cells, called platelets will clump or clot at that site to try and repair the artery.
When I am having these negative emotions, I would be unable to have relax myself therefore my stress increases causing my immune system to weaken. Before elaborating on how the immune system responds to stress, I would firstly define what is immune system and how is it build up. Immune system is our body’s defense against infectious organisms and other invaders. Through a series of steps which is called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease. It is made up of a net of cells, tissues and organs.
This report further elaborates the most common but fatal diseases on human body due to excessive alcohol intake. One of the diseases linked to excessive alcohol drinking is liver fibrosis that ultimately results in liver cirrhosis. In both these cases, the normal structure and function of the liver is altered by excessive disposition of extracellular matrix in liver. The liver looses its capability to perform its primary function: detoxification, which leads to further complications in a human body. Because of active cirrhosis, individuals are more susceptible to deadly infections such as hepatitis (Jamal & Morgan, 2003).
