  4. Definition of blood Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells

  6. Components of blood Red blood cells, which carry oxygen to the body's tissues White blood cells, which fight infections Platelets, which help blood to clot

  8. Definition of blood diseases Blood diseases are disorders affect one or more parts of the blood and prevent blood from doing its job. Many blood diseases and disorders are caused by genes. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in diet.

  10. Blood diseases affecting Red Blood Cells Anemia : People with anemia have a low number of red blood cells. Mild anemia often causes no symptoms. More severe anemia can cause fatigue, pale skin, and shortness of breath with exertion. Common types of anemia disease : 1. Iron-deficiency anemia 2. Anemia of chronic disease 3. Sickle cell anemia

  11. 1. Iron-deficiency anemia Iron is necessary for the body to make red blood cells. Low iron intake and loss of blood due to menstruation are the most common causes of iron-deficiency anemia. It may also be caused by blood loss from the GI tract because of ulcers or cancer. Treatment includes iron pills, or rarely, blood transfusion

  12. 1. Iron-deficiency anemia

  13. 2. Anemia of chronic disease People with chronic kidney disease or other chronic diseases tend to develop anemia. Anemia of chronic disease does not usually require treatment. Injections of a synthetic hormone, epoetin Alfa (Epogen or Procrit), to stimulate the production of blood cells or blood transfusions may be necessary in some people with this form of anemia.

  14. 3. Sickle cell anemia A genetic condition that affects mostly people whose families have come from Africa, South or Central America, the Caribbean islands, India, Saudi Arabia, and Mediterranean countries that include Turkey, Greece, and Italy. In sickle cell anemia, the red blood cells are sticky and stiff. They can block blood flow. Severe pain and organ damage can occur.

  17. Blood diseases affecting White Blood Cells Blood disorders that affect white blood cells include: 1. Lymphoma 2. Leukemia 3. Multiple myeloma

  18. 1. Lymphoma  A form of blood cancer that develops in the lymph system. In lymphoma, a white blood cell becomes malignant, multiplying and spreading abnormally. Hodgkin's lymphoma and non-Hodgkin's lymphoma are the two major groups of lymphoma. Treatment with chemotherapy and/or radiation can often extend life with lymphoma, and sometimes cure it.

  19. 1. Lymphoma

  20. 2. Leukemia  A form of blood cancer in which a white blood cell becomes malignant and multiplies inside bone marrow. Leukemia may be acute (rapid and severe) or chronic (slowly progressing). Chemotherapy and/or stem cell transplantation (bone marrow transplant) can be used to treat leukemia, and may result in a cure.

  21. 2. Leukemia

  22. 3. Multiple myeloma A blood cancer in which a white blood cell called a plasma cell becomes malignant. The plasma cells multiply and release damaging substances that eventually cause organ damage. Multiple myeloma has no cure, but stem cell transplant and/or chemotherapy can allow many people to live for years with the condition.

  25. Blood diseases affecting Platelets Thrombocytopenia : A low number of platelets in the blood; numerous conditions cause thrombocytopenia, but most do not result in abnormal bleeding Common types of thrombocytopenia disease : 1. Idiopathic thrombocytopenic purpura 2. Heparin-induced thrombocytopenia 3. Thrombotic thrombocytopenic purpura

  26. 1. Idiopathic thrombocytopenic purpura A condition causing a persistently low number of platelets in the blood, due to an unknown cause; usually, there are no symptoms, yet abnormal bruising, small red spots on the skin (petechiae), or abnormal bleeding can result.

  27. 1. Idiopathic thrombocytopenic purpura

  28. 2. Heparin-induced thrombocytopenia  A low platelet count caused by a reaction against heparin, a blood thinner given to many hospitalized people to prevent blood clots

  29. 3. Thrombotic thrombocytopenic purpura A rare blood disorder causing small blood clots to form in blood vessels throughout the body; platelets are used up in the process, causing a low platelet count.
