08 Cardio-Vascular System: Andrew Sanchez-Vasquez Period:5
Cardiac cycle and the ECG
Cardiac Cycle
AV Bundle( From the AV node, impulses pass to AV bundle and travel down the interventricular system)
Bundle Branches( AV bundle divides into left and right bundle branches under the endocardium)
Atrioventricular or AV Node(Passes impulses to the AV bundle)
Purkinje Fibers( Bundle Branches give off the purkinje fibers which spread impulses to the ventricular wall and papillary muscles)
Sinoatrial or SA Node( A self-exciting mass of cardiac muscle, which serves as as the facemaker)
ECG(Electrocardiogram)
QRS Complex( Corresponds to the depolarization of ventricle, the repolarization of the atria occurs, but its hidden behind the larger ventricle event)
T-Wave( Corresponds to ventricular repolarization,& leads to ventricular relaxation)
P Wave( First wave, corresponds to depolarization of the atria)
Disorders of the cardiovascular system
Stroke( Also known as Cerebrovascular Accident, this when blood flow from the brain is interrupted, this can be caused by blood cots, diabetes, symptoms are memory loss and muscle weakness, blood thinners are used as treatments options)
Endocarditis & Myocarditis( Inflammation of the heart, this can be caused by virus infection, symptoms are fatigue and chest pain, treatment options are antibiotics and reduced activity)
PAD( Peripheral Artery Disease is when Arteries are narrow and reduce blood flow to extremities, this can be caused by obesity and diabetes, leg pain and weak pulse, can be treated by bypass surgery)
Congenital Heart Disease( Issue with heart structure and/or function presented from birth, Caused by ASD and pulmonary stenosis, Death can occur, Treatments are surgery, medication and can heal on its own)
Heart Attack( Also known as Myocardial Infarction, its when blood flow to the part of the heart is blocked, chest pain, vomiting,can be treated with open heart surgery)
Major Components& Functions of the Blood
Red Blood Cells(Contain hemoglobins, Main Role: Carries Oxygen from the lungs to the rest of the body)
White Blood Cells( Part of the immune system,fight infections and diseases)
Plasma( Largest part of the blood, light yellow liquid, carries water and enzymes, Main Role:take nutrients to the correct part of the body)
Platelets(Also known as thrombocytes,come from bone marrow, play a role in blood clotting)
Anatomy of the heart( Including all chambers, and valves)
Chambers( Left&Right Atrium,Function: Receive blood from veins, Left&Right Ventricles, Functions:Pumps out blood out of the blood into the body)
Valves
Pulumonary Valve( Inside the pulmonary trunk, prevents blood from moving from the trunk into the right ventricle during relaxation)
Mitral or Bicuspid Valve( In between left atrium and left ventricle, prevents blood from the left ventricle into the left atrium during contraction)
Tricuspid Valve(Opening in between right atrium and right ventricle, Its role is to prevent blood from moving from the right ventricle into the right atrium during contraction)
Aortic Valve( In the aorta, prevents blood from moving from the aorta into the left ventricle during relaxtion)
Major Functions of the Cardio-Vascular System
Functions( Bring oxygen,nutrients to every living cell to the body, take away carbon dioxide and waste)
ABO, Rh blood types
Type B Blood( Has B antigens on RBC membranes& Anti-A antibodies in the plasma)
Type AB Blood(Has both A&B antigen on RBC membranes, but neither type of anti bodies in the plasma; Universal recipient)
Type A Blood( A Antigens on RBC membranes& Anti-B antibodies in the plasma)
Type O Blood( Has neither antigen on RBC membranes, but both types of antibodies in the plasma; universal donor)
Layer of the Heart
Myocardium( Middle Layer)
Endocardium( Inner Layer)
Epicardium( Outer layer)
Blood Flow through the heart & body Steps
9.) Bicuspid Valve
10.) Left Ventricle
8.) Left Atrium
11.) Aortic Semilunar Valve
7.) Right & Left Pulmonary Vein
12.) Aorta
6.) Right and Left Pulmonary Artery
5.) Pulumonary Semilunar Valve
4.) Right Ventricle
3.) Tricuspid Valve
2.) Right Atrium
1.)Superior& Inferior Vena Cava
Structural and functional differences between blood vessel types (arteries, veins,
capillaries)
Veins( Carry blood towards the heart, thinner than artery, smaller diameter)
Capillaries( Tiny, thin-walled, exchange blood flow with body cells, connects arterioles and venules)
Arteries( Carry away blood from the heart, Thicker than veins, more elastic fibers than veins)
Major blood vessels (names arteries and veins)
Capillary( Single layer of squamous epithelium, allows nutrients, gases and wastes between blood and tissue fluid)
Venule(Thinner wall than arteriole, connects a capillary to a vein)
Arteriole(Thinner Wall, three layers as well, connects an artery to a capillary, helps control blood flow)
Vein(Thinner wall than artery, transport blood under low blood pressure from the ventricle to the heart)
Artery(Thick, Strong wall, three layer, Transports blood under high pressure from the heart to arterioles)
Vital signs (BP and Pulse)
Blood Pressure
High Blood Pressure( Also known as hypertension, long term force on artery walls, might cause heart attack)
Low Blood Pressure( Causes fainting and dizziness, Lack of blood flow)
Pulse(Normal Range for Adults:60 to 100, may fluctuate and increase with excerise,injury and emotions)
