Hearts Primary Function
Pump blood into the arteries.
Blood Vessels Primary Function
Transport blood to and from all areas of the body
Arteries Primary Function
Transport blood away from the heart to all parts of the body.
Capillaries
Permit the exchange of nutrients and waste products between the blood and the cells.

Right Atrium (RA) Blood Flow
Receives oxygen poor blood from all tissues except the lungs.
Right Ventricle (RV) Blood Flow
Pumps onygen poor blood through the pulmonary semilunar valve and into the pulmonary artery, which carries it to the lungs.
Left Atrium (LA) Blood Flow
Receives Oxygen-rich blood from the lungs through the four pulmonary veins.
Left Ventrical (LV) Blood Flow
Received oxygen rich blood from the LA. Blood flows to all parts of boy except lungs.
Venae Cavae part in blood flow
Oxygen poor blood is returned to the VC ro the right Atrium
Arterioles Function
The distal branches of the arteries that carry blood to the capillaries. Help to determine blood pressure.
Capillaries primary function
Permit the exchnce of nutrients and waste products between blood and the cells.
Veins primary function
Return blood from all body parts to the heart
Name 3 components of blood
Erythrocytes, Leukocytes, Thrombocytes
Thrombocytes
Platelets - assist in clotting
Blood is 55% what?
Plasma
Blood is 45 % what?
Formed Elements, Red, white and platelets.
Pulmonary Circulation is the flow of blood between
The heart and lungs only!
Systemic blood flow includes
Blood to all parts of the body except the lungs
ACE Inhibitor
Angiotension Convertin Enzyme inhibitor. Popular antihypertensive drug.
Anemia
Lower than normal erythrocytes
Aneurysm
Soft spot in a blood vessel
Angioplasty
Surgical repair of blood vessle
Anticoagulant
Drug that prevents clotting
Aplastic Anemia
Lower than normal blood cells of all types
Arrythmia
Irregular heart beat
Atheroma
Characteristic of Athreosclerosis - deposit of plaque on or withing the arterial wall
Atrial Fibrillation
Excessive beating of the arteria
Beta-blocker
Drug that slows heart & reduces BP by blocking beta receptors
Blood Dyscarsia
Any pathologic condition of the cellular elements of the blood.
Bradycardia
Slow heart rate
Cardiac catheterization
Placing a tube in the heart
Cardiomyopathy
Disease of the heart muscle
Carotid Endoarterectomy
Surgical removal of the lining of a portion of a clogged artery
Cholesterol
A form of lipid found in the blood
Coronary Thrombosis
A blood clot in a coronary vessel.
defibrillation
normalizing depolarization of heart muscle
diuretic
drug that increases urine output
electrocardiogram
recording of electrical activity of the heart
Embolism
blockage of a blood vessel by embolus
Embolus
clot or fat or other substance "inserted" into a blood vessel
Endocarditis
inflammation in heart lining
Hemoglobin
molecule that transports oxygen in blood
hemolytic anemia
low numbers of erythrocytes because of red cell destruction
homeostasis
maintaining normal blood conditions
Ischemic heart disease
not enough blood reaching heart muscle
leukemia
cancer that causes too many white blood cells
leucocytes
white blood cells
leucopenia
less than normal blood cells
Megaloblastic anemia
Blood disorder in which red cells are excessively large
Myocardial infarction
injury of heart muscle due to inadequate oxygen
Orthostatic hypotension
low blood pressure upon standing
pernicious anemia
low red cells due to low vitamin B12
Phelbitis
inflammation of veins
Raynaud's Phenomenon
Peripheral artery disease often made worse by cold
Septicemia
infection in blood
Sickle cell anemia
inherited anemia most common in people of African descent
Tachycardia
excessive heart rate
Thrombolytic
drug that breaks up clots
Thrombus
Clot
Valvulitis
inflammation of the heart valve (s)
Vericose Veins
enlarged veins
Ventricular fibrillation
useless contractions of ventricular muscle, fatal if not reversed
ventricular tachycardia
A rapid heart beat in the ventricles
Arterioles
distal end of artery - assist in blood pressures
SA (sinoarterial) Node
located in the posterial wall of the RA near the entrance of the superior vena cava. Establishes a basic rythm and rate of the heartbeat.
What is the "Natural Pacemaker."
The SA (sinoarterial) Node.
AV (atrioventricular) Node
Located: Floor of RA. Transmits electrical impulses to the Bundle of His.
Plasma
Fluid in blood containing hormones, nutrients and waste products.
Serum
Is plasma fluid after blood cells and the clotting proteins have been removed.
Atherosclerosis
abnormal hardening of the artery
Atherosclerosis is caused by what?
cholesterol plaque building up on the interior wall of the artery
Angina
episodes of chest pain due to inadequate blood flow to the myocardium.
Heart Murmur
An abnormal sound herd when listening to the heart
Hemangioma
A benign tumor made up of newly formed blood vessels
polycythemia
abnormal increase in the number of red cells in blood due to an excessive production from bone marrow.
Hemolysis
destruction of red blood cells.
Hypertension
high blood pressure
Hypotension
lower than normal arterial blood pressure.
Holter monitor
Portable electrocardiograph that is worn by an ambulatory patient over a 24 hr period to monitor heart rate.
