Coronary heart disease kills over 110,000 people in England every year, not the United Kingdom, just England. This figure shows how serious coronary heart disease can be. Coronary heart disease, also known as CHD for abbreviation is the build up of atheromatous plaques (otherwise known as Atheroma, or the accumulation of inflamed cells) in the arteries that send blood to the myocardium. The myocardium is the muscle of the heart.
Ischaemic heart disease is the lesser-known name of the condition that is the biggest killer out of all heart diseases across Europe and America. What is Ischaemic heart disease? Ischaemia means reduced blood supply, so Ischaemic heart disease is the reduction in the blood supply to the heart. The blood supply is affected by the narrowing of the coronary arteries; the danger of this is that the coronary arteries are the only arteries that carry blood to the heart.
There are two main classifications of lymphoma, the Hodgkins lymphoma, named after Thomas Hodgkin who discovered the disease in 1832 and the Non-Hodgkins group which is composed of about 30 types of lymphoma which were discovered by scientist after 1832. All types of lymphoma have different characteristics and behavior although the target of the cancer cells is the same, the lymphatic system. Non-Hodgkins lymphoma is rather a large group and is further classified into two types, the slow growing or the low-grade type and the aggressive or the high-grade type.
No longer is the swimming pool the sole preserve of swimmers. Water aerobics has greatly changed this concept because the benefits of water exercises are many. Water aerobics are instrumental in improving the cardiovascular fitness and also result in better endurance through use of muscles which gain in strength. As a result of the buoyancy that water provides as well as the support that a body receives from water there are fewer worries about getting muscle, bone or joint injuries.
What is osteoarthritis? Who will it affect and how does it cause back pain? Osteoarthritis is the most common of the arthritis varieties that affect people. It is more likely to be a problem, as a person grows older. Presently about twenty one million Americans are suffering with it. In the next twenty-five years this will be closer to seventy million ho are over sixty-five with the potential for this condition.
Sciatica is a common form of pain in the lower back (otherwise known as the lumbar region). Sciatica has actually been a medical term since the medieval times; it was first recorded as being used around 1450. The back pain called sciatica is caused by the compression of the sciatic nerve, this can sometimes happen due to a spinal disc herniation, otherwise known as a bulging disc. When a disc bulges it pushes cartilage out of its usual place and this can sometimes catch on a nerve root, including the sciatic nerve.
In dermatology epithelium is a tissue composed of a layer of cells. In humans, it is one of four primary body tissues. Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies. The outermost layer of our skin is composed of dead stratified squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities. Other epithelial cells line the insides of the lungs, the gastrointestinal tract, the reproductive and urinary tracts, and make up the exocrine and endocrine glands.
Corpora amylacea, also known as amyloids, is the accumulation of dense amounts of calcified materials that are protein based in nature. Corpora amylacea normally affects men who are more senior in age, by this we mean men over the age of about sixty years old.
