Chapter 13 Heart & Disease

QuestionAnswer
System that supplies are cells transportation is the? Circulatory System
Blunt point at the edge of the lower heart that lies on the diaphram Apex
Divides the Heart into Right and Left sides between the Atria Interatrial Septum
Upper Chambers of the heart Right and Left Atria they are receiving chambers
Lower Chambers of the Heart Right and Left Ventricles they are discharging chambers
Cardiac Muscle tissue is referred to as Myocardium
The inner lining of the Myocardium Endocardium
Inflammatin of the Endocardium Edocarditis-imflammed Endocardium can become rough & abrassive causing Thrombus
The two Antrioventrricular Valves (AV Valve) Tricuspid Valve-Located at the opening of the Right Atrium into the Ventricle. Bicuspid Mitral Valve Located at the opening of the Left Atrium into the ventricle
The Two Semilunar Valves (SL Valves) Pulmonary Semilunar Valve Located at the beginning of the Pulmonary Artery. Aortic Semilunar Valve Located at the beginning of the Aorta
Pericardium Two layered fibrous sac with a lubricated space between the two layers
Inner layer of the Pericardium Vesceral Pericardium or Epicardium
Outer layer of the Pericardium Parietal Pericardium
Inflammation of the Pericardium Paricarditis
Cardiac Tamponade Compression of the heart that is caused by fluid between the Vesceral Pericardium and the Parietal Pericardium
They are located between the two Ventricle chambers and the larger arteries that carry blood away from the heart when contraction occurs Semilunar Valves - Pulmonary Semilunar and the Aortic Semilunar Valve
A condition caused when the flaps of this valve extends back into left atrium causing the valve to leak Mitral Valve Prolapse
Cardiac Damage Resulting from a delayed inflammatory response to Strepococcal Infection and occurs mostly in children Rheumatic Heart Disease
Movement of blood from the left Ventricle through the Body Systemic Circulation
Blood Clot Embolism
Myocardiac Infarction is a Heart Attack
Abnormal Heart sound often caused by disorders of the valves Heart Murmur
Movement of blood From the Right Ventricle to the Lungs Pulmonary Circulation
Hardening of the Arteries is called Atherosclerosis
Severe chest pain caused by inadequate oxygen to the Heart Angina Pectoris
High Blood Pressure is also called Hypertension
Structure through which blood returns to the left atrium Pulmonary Veins
Treatment for certain Coronary Disorders Coronary Bypass
The heart beats an average of 72 beats/min
Each complete beat of the Heart is called A Cardiac Cycle
The pacemaker of the Heart is also called the Sa node + Sinoatrial Node
Rapid Heart Rhythm over 100 beats/min Tachycardia
The term that describes the electrical activity that triggers contraction of the Heart Muscle Depolarization
A diagnostic tool that uses ultrasound to detect valve and heart disorders is known as a Echocardiogram
Frequent premature contractions can lead to Fibrillation
A drug that slows and increases the strength of the cardiac contraction is Digitalis
Congestive Heart Failure enevitable causes Pulmonary Edema
Failure of the right side of the heart due to blockage of pulmonary blood flow is called Cor Pulmodale
Coumadin and Dicumarol are examples of commonly used Oral Anticoagulants
upper Nodes Sa Node: Sinoatrial Node located in the wall of the Right Atrium near the opening of the Superior Vena Cava. Av Node: Atrioventricular Node located in the wall of the Right Atrium in the interatrial Septum
Lower Nodes Av Bundle or Bundle of His located in the Septum of the ventricle. Purkenje Fibers located in the walls of the ventricles
Location, Size & Postion of the Heart Triangular Organ located in the mediastinum 2/3 of the mass to the left of the body midline and 1/3 to the right, the apex is in the diaphram and is the size of a closed fist.
Heart Chambers Two upper - R & L Atrium - Receiving Chambers Two Lower - R & L Ventricle - Discharging Chambers.
Walls of each chamber is composed of Cardiac Muscle called Myocardium Endocardium is the smooth lining of the chamber
What do the Heart Valves do? Valves keep the blood flowing through the heart and prevent backflow
Two distinct sounds of the Heart Lub- first sound caused by the vibration and closure of the AV valve during he contraction of the ventricle. Dup -Second Sound is caused by the Closure of the SL Valves during relaxation of the Ventricles
Heart Murmur Abnormal Heart sounds caused by abnormal valves
The Superior Vena Cava carries blood to the Right Atrium
The outside covering that surrounds and protects the heart is called the Pericardium
Thin walled upper heart cavities that recieve blood from the veins is called Atria
A valve that permits blood to flow from the right ventricle into the pulmonary arter is called the Pulmonary Semilunar Valve
Ventricular contraction of the heart occurs immediately after depolarization of the Purkinje Fibers
A variation in Heart rate during the breathing cycle is called Sinus Dysrhythmia
BradyCardia Slow Heart Rhythm lower than 60 beats/min
TachyCardia Rapid Heart Rhythm more then 100 beats/min
Sinus Dysrhythmia Variation in Heart Rhythem during the breathing cycle
Premature Contraction or Extrasystole Contraction that occurs sooner than expected in a normal rhythm
Fibrillation Condion in which cardiac muscle fibers are out of step. Producing no effective pumping action
Heart Failure Inability to pump enought returned blood to sustain life. It can be caused by many different Heart Diseases
Right Heart Failure Failure of the Right side of the Heart to pump blood effectively usually caused b the left side of the heart to pump blood effectively
Left Heart Failure Failure of the left side of the Heart to pump blood effectively.Resulting in congestion of the Systemic & Pulmonary Circulation
Heart Beat Regular Rhythm each complete beat is called a Cardiac Cycle. Average beats is 72 beats/min. Cycle is 0.8 second long subdivided into Systole & Diastole
Stroke Volune The volume of blood ejected from the ventricle with each beat
Cardiac Output The amount of blood that one ventricle can pump each minute
Valve Disorder Called Incompetent Valve Leaky- allowing some of the blood to flowback into the chamber from which it came
Valve Disorder called Stenosed Valve Narrower than normal, reducing blood flow
Valve Disorder called Rheumatic Heart Disease Cardiac Damage caused by delayed inflammatory response to Streptococcal Infection
Valve disorder called Mitral Valve Prolapse Incomptence of the Mitral valve caused by it edges extending into the left atrium when the left ventricle contracts
The ECG 3 deflection or waves is called P Wave, QRS Complex, & the T Wave
P Wave Associated with the depolarization (contraction) of the Atria
QRS Complex Associated with the depolarization (contraction) of the Ventricle
T Wave Associated with repolarization (relaxtion) of the ventricle
