Blood Flashcards
Cirrhosis
Liver disease caused by cancer, alcoholism, hepatitis. Could eventually lead to exéma
Thrombocytopenia
Number of platelets are low
Leukaemia
Cancers of the blood cells or bone marrow
Thrombus
Clot formed in an I damaged blood vessel. Causes thrombosis
Embolus
Dislodged thrombus travelling through blood
(Pieces of platelets, air bubbles, fat from broken bones, etc.)
Causes ventricular failure & death in lungs
Stroke in the brain
Kidney failure
Heart attack
Hemophilia
Shortage of one clotting factor
Hypoxia
Lack of O2 from High altitude, lung disease Reduced number of erythrocytes Exposure to CO increased demand for O2 by the body
Anemia
O2 carrying capacity lower than normal
Hemorrhagic anemia
Lack of erythrocytes
Acute/chronic blood loss through large wounds, stomach ulcers or heavy menstruation
Hemolytic anemia
Lack of erythrocytes
RBCs rupture prematurely and hemoglobin enters the kidneys, where it causes damage to the nephrons.
Causes of premature destruction of RBCs varying from genetic disorders to incompatible blood transfusions
Aplastic anemia
Lack of erythrocytes
Destruction or inhibition of red bone marrow caused by toxins, radiation exposure and certain medications that inhibit the enzymes involved in hématopoïèses
Fe+ deficiency
Low hemoglobin content
Most common
Pernicious anemia
Low hemoglobin content
From a lack of intrinsic factor that is produced by the stomach that is needed for absorption of VitB12 in the small intestine
Megaloblastic anemia
Abnormal RBC/hemoglobin
From inadequate intake of VitB12 or folic acid caused by drugs
Thalassemias
Abnormal RBCs/hemoglobin
Genetic hemolytic anemia creating thin pale delicate RBC
