L4 Anatomy of Heart

• anemia - decreased rbc count
• leukemia - cancer of the blood
• UTI - shown by increased number of WBC
• leukocytosis - increased number of WBC in blood
• leukopenia - decreased number of WBC in blood
• polycythemia - produces too many RBCs
• thrombocytosis - increased platelets
• thrombocytopenia - decreased platelet count
• lymphangitis - inflammation of lymphatic channels
• lymphadenitis - inflammation of lymph nodes
• lymphadenopathy - abnormality in size or number of lymph nodes
• splenomegaly - enlargement of spleen
• hodgkin disease - cancer that affects immune system and enlarged lymph nodes
• lymphosarcoma - type of cancer that develops lymphocytes
• lymphoma - cancer of lymphatic system that begins in lymphocytes
• septum - divides middle into left and rgith sides
• right atrium - receives deoxygenated
• right ventricle - pumps into pulmonary artery
• left atrium - receives oxygenated blood from lungs
• left ventricle - pumps blood into aorta
• endocardium - inside layer lines the valve and interior chambers
• myocardium - thick layer, pumps blood into the arteries through contractions
• epicardium - outermost thin watery membrane covers the heart, attached to pericardium
• visceral - serious, inner

  parietal - fibrous, outer
• tricuspid valve - right AV valve
• bicuspid valve - left AV valve
• pulmonary valve - entrance of pulmonary artery
• left semilunar valve - aortic valve located in the entrance of aorta
• cardiac cycle - one heartbeat
• systole - 120, pressure created die to muscular contraction
• diastole - 80, product of muscular relaxation
• electrocardiogram - provides graphical representation of heart's activity
• lubb first sound, dupp second sound
• heart rate - 60-90 normal beat per min, 72 beats average
• cardiac output - volume of blood pumped per minute
• pulse - rhythmic throbbing resulting from the alternating expansion and contraction of artery
• blood pressure - force exerted by blood on the walls of vessel mesured by sphygmomanometer
• angina pectoris - chest pain, reduced blood flow
• aortic stenosis - heart murmur
• bacterial endocarditis - inflammation of endocardium
