A | B |
Blood is received by the _____ then passes through _____ valve to the _____ | Right Atria, tricuspid, right ventricle |
From the right ventricular blood passes through the _______ clave to the lungs for oxygenation | Pulmonary (Semi lunar) |
Oxygenated Blood returns from the lungs to the ________ through the _______ valve to the ______ | Left atria, bicuspid, left ventricular |
From the left ventricle the blood is pumped through the _______ valve to the body | Aortic |
Arteries carry blood | Away from the heart |
Veins carry blood from | The body back to the heart |
Coronary arteries | Supplies oxygenated blood to the heart muscle (myocardium) |
ECG (ELECTROCARDIOGRAM) | Measures electrical activity of the heart |
Capillaries are the smallest vessels where | Exchange of water, nutrients, and waste products takes place |
Sinoatrial node initiates the | Heartbeat |
Systole | contraction phase of cardiac cycle |
Diastole | Relaxation phase of the cardiac cycle |
Anemia | Reduction of hemoglobin to below normal levels which can result in hypoxia (low oxygen) |
Anemia may results from | Decreased hematopoesis (production of red blood cells); abnormal hematopoesis; increased loss or destruction of red blood cells |
Splenomegaly, enlargement of spleen, is caused by | Spleen Removes old blood cells and in acceleted removal of some disease enlargement of spleen occurs |
Thalassemia, occurs in people of Mediterranean descent | Hereditary defect affecting synthesis (production) of RBCs |
Hemolytic anemia is a | Micro cytic, hypochromic anemia; Is the destruction of RBCs, most common cause is malaria |
Macrocyclic, normochromic anemia | B12 and/or folic acid deficiency |
Sickle cell anemia is characterized by | Abnormal red blood cell shape (sickled) |
Aplastic anemia | Characterized by leukopenia (decreased white blood cells) and thrombocytopenia (decreased platelets) |
2 forms of aplastic anemia | Idiopathic (no identifiable cause) and secondary aplastic anemia (caused by cytotoxic drugs, radiation, or virtual infection) |
Signs of aplastic anemia | Infections due to luekopenia, bleeding tendency due to thrombocytopenia and fatigue and weakness |
Iron deficiency anemia, most common form of anemia, is a hypochromic, microcytic anemia caused by | depletion of irony stores caused by chronic blood loss |
Iron deficiency anemia can be caused by | Increased loss of iron, inadequate iron absorption, increased iron requirements (child growth and pregnancy) |
Megablastic anemia is caused by | Deficiency of B12 or folic acid, two essential cofactors for DNA synthesis |
Pernicious anemia, is the most common form of B12 deficiency and develops as a result of | Lack of intrinsic factor in the intestines and antibodies to intrinsic factor |
Hemolytic anemia | Malaria is the most common infectious cause |
Polycythemia | Also called erythrocytosis denotes an increased number of red blood cells |
Luekopenia | Decreased white blood cells |
Thrombocytopenia | Decreased platelets |
Hereditary spherocytosis | Example of intracorpuscular defect in hemolytic anemia |
Disseminated intravascualar dissemination (DIC) | Example of extracorpuscular defect in hemolytic anemia |
