Cardiovascular System Test Review Flashcards
Erythrocytes
Red blood cells
Leukocytes
White blood cells
Neutrophis
Most common type of WBC
Capillaries
Deliver oxygen and neutrients to cells of tissues
Veins
Carry oxygen- poor blood to the heart
Arteries
Carry oxygen- rich blood away from the heart
Pulmonary vein
Carries oxygenated blood
Pulmonary Artery
Carries deoxygenated blood
Atria
Two upper chambers of the heart that receive blood
Ventricles
Two lower chambers of the heart that pump blood
Septum
Separates heat into left and right
Endocardium
Smooth inner layer of the heart
Myocardium
Thickest muscle layer of the heart
Epicardium
Thin outermost layer of the heart
Diastolic Pressure
Ventricles are relaxed (low)
Systolic Pressures
Ventricles contract (high)
Embolism
Blockage of a blood vessel by a embolus
Thrombus
Blood clot attached to the inner wall
Coronary Thrombosis
Damaged heart muscle caused by a thrombus
Deep Vein Thrombosus
Thrombosis attached to the wall of a deep vein
Thrombocytopenia
Abnormally small platelets circulating in the blood
Leukemia
Abnormal increase of WBC
Anemia
Low number of RBC
Sickle cell anemia
Abnormal hemoglobin
Iron- deficiency anemia
Insufficient iron that blood cannot carry oxygen effectively
Megaloblastic anemia
Larger than normal red blood cells
Hemochromatosis
Blood disease
Arrhythmia
Abnormal heart beat
Bradycardia
Abnormally slow heart beat
Tachycardia
Abnormally rapid heartbeat
Congestive Heart Failure
When the heart isn’t able to pump out blood it receives (build-up)
Cardiac Arrest
When the heart stops beating
Cardiomyopathy
Disease of the heart muscle
Carditis
Inflammation of the heart muscle
Endocarditis
Inflammation of the inner wall of the heart
Myocardial infraction
Interruption of blood supply to the heart (heart Attack)
Atherosclerosis
Hardening and narrowing of arteries caused by build-up
Aneurysm
Ballooning and weakening of an artery
Varicose veins
Swollen veins that causes blood to pool
Phlebitis
Inflammation of the veins
Ischemia
Inadequate blood supply
Valvular prolapse
Improper closure of the valve
Septicemia
Blood poisoning
