What is the function of the cardiovascular system?
To maintain blood pressure in the arteries and blood flow (perfusion) to the tissues, delivering oxygen, transporting hormonal messages and picking up waste products. The heart is the pump for this system.
What is the high pressure circulation system that delivers oxygenated blood to the body, returns deoxygenated blood to the heart?
Systemic Circulation
What is the low pressure circulation system, that delivers deoxygenated blood to lungs, returns oxygenated blood to the heart?
Pulmonary Circulation
What is the circulation system that is a separate blood supply system to the heart muscle itself?
Coronary Circulation.
Take a look!
Systemic Circulation
What are vessels that carry blood to the heart?
Veins
What are vessels that carcy blood away from the heart?
Arteries
What are the only arteries that carry deoxygenated blood?
Pulmonary Arteries
What are the only veins that carry oxygenated blood?
Pulmonary Veins

Pulmonary Circulation
Take a look!
Coronary Circulation
What are the Cardiovascular functions?
Maintain normal blood pressure within arteries.
Maintain blood flow to tissues.
Maintain normal blood pressure within capillaries and veins.
Maintain these funections in rest and in work.
What is Tissue Perfusion?
Delivery of O2 and nutrients to tissues.
Removal of waste products.
Transport of hormonal messages from one part of the body to another.
What is the force exerted by the blood against the inner walls of the blood vessels?
Blood Pressure

(Typically refers to systemic blood pressure)
What is the maximum pressure achieved during ventricular contraction?
Systolic Blood Pressure
What is the lowest pressure that remains in the arteries when the ventricles are relaxing?
Diastolic Blood Pressure
What is the difference between systolic and diastolic pressure called?
Pulse Pressure
What is the space between the two pleural cavities that contain the lungs - dividing the pleural spaces into left and right sides?
Mediastinum
What is the area on the right ventrolateral thorax where the heart makes contact with the chest wall? (elsewhere surrounded by lung)
Cardiac Notch
Take a look!
Mediastinum
What is the double walled connective tissue layer over the heart?
Pericardium
The out layer of the pericardium is called the?
Fibrous Pericardium
The inner layer of the pericardium is called the?
Serous Pericardium
The pericardium creates the potential space known as the?
Pericardial Space
What is the visceral layer of the serous pericardium of the covering the heart?
Epicardium
What is the word pertaining to the wall of an organ or cavity?
Perietal
What is the word pertaining to the soft internal organs?
Visceral
Take a look!
Pericardium
What is the heart muscle layer called?
Myocardium
What is the thin membranous lining layer of the inner chambers of the heart - the ventricles and atria are called?
Endocardium
The Fibrous Skeleton of the heart does what?
Seperates the heart into atrial and ventricular areas.

Tissue does not conduct electrical impulses.

Serves as an anchor for the atrioventricular valves.
What does auscultation mean?
Listening
If the fetal hole between the atria fails to close what is the defect called?
Atrial Septal Birth Defect
What delivers venous blood from the coronary circulatory system into the atrium?
Coronary Sinus
Take A Look!
Atrial Septal Birth Defect
Right ventricle pumps deoxygenated blood into the?
low pressure pulmonary circulation.
What band runs from the interventricular septum to the free wall?
Moderator band
What prevents blood from flowing retrograde into the right atrium with ventricular contraction?
Tricuspid
Right Atrioventricular Valve
(AV Valve)
What prevents blood from flowing retrograde from pulmonary artery back into right ventricle?
Semilunar valve
(Pulmonic Valve)
What prevents backflow of blood from the left ventricle into the atrium?
Mitral Valve
Left Atrioventricular Valve
(AV Valve)
Which ventricle is a high pressure system with walls 2 to 3 times thicker and no moderator band?
Left Ventricle
What valve prevents backflow into the left ventricle during diastole?
Aortic Valve
Know for Exam

Know the three cardiovascular systems

Be able to label the 4 chambers and valves of the heart

Which arteries carry deoxygenated blood?

Trace the flow of blood through the heart and label each part
Do I know these?
What creates the first S1 "Lub" sound?
Closure of the AV valves creates the first heart sound.
What is the term for the amount of blood leaving the heart?
Cardiac Output
What is the term for the difference between systolic and diastolic pressures of the expanding and contracting arterial walls?
Pulse Pressure
What is the specialized area of cardiac muscle in the right atrium (Pacemaker) that spontaneously depolarizes?
Sinoatrial (SA) node
When the Sinoatrial (SA) node spontaneously depolarizes a wave of depolarization takes two routes! What are they?
1. AV node via conductive fibers. (Highway Route)

2. Across Both Atrial Myocardium to Stimulate Arterial Contraction
- Slower local route
- Via cell to cell interaction
- Stoped by the fibrous skeleton at the bottom of the atria.
Depolarization Pathway
Depolarization Pathway
What is a diseased myocardium which spontanously depolarizes called?
Ectopic Pacemakers
What is a heart muscle cells contracting independently of each other and so coordinated pumping is lost called?
Ventricular Fibrillation
What is a large electrical current in attempt to repolarize all the cells at the same time called?
(Reset)
Defirbrillator
Cardiac Ouput X Peripheral Resistance / Vessel Constriction Equals?
Blood Pressure = Cardiac Ouput X Peripheral Resistance / Vessel Constriction
Stroke volume X heart rate equals?
Cardiac Output = Stroke Volume X Heart Rate
What is the volume of blood in the ventricle right before it starts to contract called?
EDV - (End Diastolic Volume)
Preload
Preload is?
EDV - (End Diastolic Volume)
What is the volume of blood left in the ventricle at the end of systole?
ESV - (End-Systolic Volume)
What is the S2 "Dub" sound from?
Semi-lunar valves (pulmonic: aoritc) close.
What is it called when all valves closed, ventricles relax and pressure inside the ventricle decreases?
Isovolumetric Relaxtion
