Sickling in sickle cell anemia is caused by the presence of an abnormal form of hemoglobin that reduces the amount of atomic number 8 the red cells can carry, and causes them to become sickle-shaped (74). The anemia is exacerbate by any condition which step-ups the soundbox's requirement for oxygen, e.g. vigorous exercise, riding horse climbing, flying at high altitudes without sufficient oxygen, or illness.
tolerant thrombocytopenic purpura is caused by infection with the human immunodeficiency virus (HIV) which causes AIDS, and as well as causes the production of antibodies which destroy platelets (756). Systemic lupus erythematosus also causes thrombocytopenia by producing antibodies against platelets.
Acute lymphocytic leukemia is the most common childhood cancer, method of accounting for 25 percent of all cancers in children under geezerhood 15, and most commonly affecting children between the ages of three and f
Iron deficiency anemia is caused by blood bolshie in adults, or a feed low in weigh in children (743). Blood loss can be sudden, e.g from an injury or a nose bleed, or chronic, as from a stomach ulcer or colon cancer. Menstrual bleeding may cause iron deficiency anemia in premenopausal women.
Teratology of Fallot is a combining of four boob defects consisting of a large ventricular septate defect; displacement of the aorta, allowing oxygen-depleted blood to flow directly from the dependable ventricle to the aorta; a narrowing of the outflow passage from the advanced side of the warmheartedness; and a thickening of the wall of the effective ventricle (1229). This means that blood circulating through the body is not sufficiently oxygenated.
Lesson 10: Alterations in Blood contract and Vascular Function
Pathology and compensatory tools for heart failure: heart failure (congestive heart failure) is a condition in which the blood cannot pump exuberant blood each minute to meet the body's normal requirements for oxygen and nutrients (Berkow, Beers and Fletcher, 1997, 87-88). The condition usually worsens slowly over time. Any disease which affects the heart and circulation can lead to heart failure, such as high blood pressure, faulty valves, myocarditis, diabetes, and obesity. The most common cause is CAD. If the heart has to work harder for an extended time, it enlarges, and initially responds with a stronger contraction, however ultimately this leads to decreased pumping pressure and heart failure. The initial compensatory mechanism is the production of epinephrine and norepinephrine in the "fight or flight" response, which causes the heart to work harder. This provides a temporary increase in blood delivery, but over time, it weakens the heart yet and heart function deteriorates. The kidneys respond by conserving salt, which retains water in the body, expanding the blood volume and initially improves performance of the heart, but this stretches the heart muscle, and
