Question | Answer |
hemorrhagic anemia | anemia resulting directly from loss of blood |
hemolytic anemia | decreased survival of mature erythrocytes and inability of bone marrow to compensate for the decreased life span |
aplastic anemia | bone marrow suppression with replacement of the hematopoietic cells by fat |
iron deficiency anemia | inadequate iron results in no hemoglobin synthesis |
pernicious anemia | deficiency of V. B12 preventing stem cell division in bone marrow |
thalassemia | inability to produce adequate amounts of normal protein subunits of hemoglobin |
sickle cell anemia | mutation of amino acid sequence upon releasing bound O2 they sickle which can cause blockage |
polycythemia | an increase in the total cell mass of the blood |
leukopenia | reduction of the number of leukocytes in the blood |
leukemia | cancers of blood forming tissues that circulate throughout the body 2 types: myeloid & lymphoid |
infectious monomnucleosis | caused by the Epstein-Barr virus its primary symptoms of fatigue and lack of energy |
thrombus | a stationary blood clot along the wall of a blood vessel |
embolus | a mass of clotted blood or other material brought by the blood from one vessel and forced into a smaller one, obstructing the circulation |
hemophilia | inherited reduced production of a single clotting factor which results in excessive bleeding |
thrombocytopenia | An abnormal decrease in the number of platelets in circulatory blood. |
pericarditis | inflammation of the pericardium makes heart work harder |
cardiac tamponade | compression of the heart due to fluid accumulation in pericardial cavity restricting movement & could increase Heart rate |
cardiac cells are connected by | desmosomes & gap junctions |
Pericardial cavity | location: area between 2 spaces
contains pericardial fluid - function = reduces friction |
parietal pericardium | serous membrane that forms the outer wall of pericardial cavity & has dense fibrous layer; Tissue: areolar & mesothelium |
visceral pericardium / epicardium | serous membrane covers the outer layer of heart |
fossa ovalis | depression in septum, fetal remnant in right atrium |
