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.
Sickle-cell anaemia is a form of sickle-cell disease in which there is homozygosity for the mutation that causes HbS. The inherited abnormality causes a pathological condition that can lead to death and severe complications. Sickle-cell disease occurs more commonly among people whose ancestors lived in tropical and sub-tropical sub-Saharan regions where malaria is common. Where malaria is common, carrying a single sickle-cell gene (sickle cell trait) confers a fitness. Specifically, humans with one of the two alleles of sickle-cell disease show less severe symptoms when infected with malaria.
An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically. A hemorrhagic stroke typically occurs when the blood vessel walls weaken over time, which leads to a bulge or rupture of the vessel. Aneurysm is the most common type of hemorrhagic strokes with a low survival rate. They also kill brain cells, which can never regenerate. The affect of strokes on the body can range between mild dizziness or slight numbness to impaired speech and loss of motor control.
The Awareness of Sickle Cell and Beta Thalassemia Sickle Cell is an inherited blood disorder that affects hemoglobin in red blood cells. The hemoglobin in people with sickle cell is abnormal (Borgna-Pignatti 101). In order to have sickle cell disease, a person must inherit the disease from both parents. When the red blood cells sickle, they block blood flow throughout blood vessels. Blocked blood flow can cause damage to organs, pain attacks, or death.
Kidneys: A wide range of kidney diseases can occur in Alagille syndrome. The kidneys can also have decreased function. (1,3) [pic] One of the major elements of Alagille disease is malfunctions to the liver. Liver damage can be caused by abnormalities in the bile ducts. Bile ducts carry bile from the liver to the gallbladder, and bile is what helps to digest fats.These bile ducts may be limited and tight, so the bile gets trapped and will build up inside the bile ducts which prevent the liver from working to its best ability (1,3).
●People from the Indian subcontinent are more susceptible to heart disease not only from small lifestyle issues but mainly genetically passed down from their ancestors. ●Rickets in a bone disease in children that our deficient of vitamin D and iron, this deficiency comes from the pigment in their skin not being able to absorb the vitamin D via the sunlight. Poor diet and poor use of vitamins are also other factors along with the birth mother passing on the deficiency to the unborn child. ●Sickle cell is an inherited disorder affecting the red blood cells which grow abnormally which causes them to distort to a ‘sickle’ shape which clogs the blood vessels causing all sorts of issues with the heart and lungs. Identify a strategy or policy that might help to reduce health inequalities in this area.
Without a blood supply, the affected skin becomes starved of oxygen and nutrients and begins to break down, leading to an ulcer forming. Pressure ulcers tend to affect people with health conditions that make it difficult to move, especially those confined to lying in a bed or sitting for prolonged periods of time. Conditions that affect the flow of blood through the body, such as type 2 diabetes, can also make a person more vulnerable to pressure ulcers. Learn more about the causes of pressure ulcers. Who is affected?
The invading organism causes symptoms, in part, by provoking a large immune response in the lungs. The capillaries become leaky, and protein-rich fluid seeps into the alveoli. This results in a less functional area for oxygen-carbon dioxide exchange. The patient becomes relatively oxygen deprived, while at the same time retaining large amounts of carbon dioxide. During this process, mucus production is increased.
Coronary heart disease is a condition in which blood to the heart is deficient because of a narrowing or constricting of the cardiac vessels that supply it. This is due to atherosclerosis (cite text). Atherosclerosis is when fatty deposits known as plaque formation, begin to accumulate to reduce the size of the passageway of the large arteries (cite). Atherosclerosis can also reduce the blood flow which may result in angina pectoris. With angina comes shortness of breath and pain from beneath the breastbone, in the neck, and down the left arm.
These fluids collect in and around the alveoli, and the alveolar walls thicken. Both events seriously reduce gas exchange and lead to hypoxemia, interfering with oxygenation and possibly leading to death. The capillary leak spreads the infection to other areas of the lung. If the organisms move into the bloodstream sepsis occurs. (3) Etiology: Pneumonia develops when the immune system cannot combat the virulence of the invading organisms.
