Cardiovascular System Flashcards
Learn Basic Cardiac Anatomy
Name the layers of the heart wall.
Pericardium
pericardial space
epicardium
myocardium
endocardium
What is the average heart beat?
60-100 BPM
What is the normal total output per min of the heart?
5L/min
How big is the normal heart? (size and weight)
size of fist, weighs 200 grams
What is the function of the heart?
pump blood to and from body tissues
Define and describe the function
Where and what does the pericardium do?
surrounding the heart
protects the heart from infection and trauma
Name the 2 layers of Pericardium and their function
Parietal: tough outer layer
Visceral/epicardium: innerlayer that adheres to heart
Where is the pericardial space located and what is its function?
between parietal and visceral layers of pericardium
Cushions against trauma
Define
Which layer of the heart is the myocardium? Which layer is it?
Middle, muscular layer
Define
Where is the epicardium/pericardium located? What is its function?
outer layer,
thin, contains c oronary arteries
Define
What is found in the endocardium layer? Where is it located?
Inner layer,
lines surfaces of the heart chambers and valves,
location of Purkinje Fibers
Name the Heart Valves
Tricuspid
Mitral/bicuspid
Pulminary semilunar
aortic semilunar
Name the chambers of the heart
Right atrium
Right Ventricle
Left atrium
Left ventricle
Where is the Tricuspid valve located?
between right and atrium and right ventricle
Where is the Mitral/bicuspid Valve located?
between left atrium and left ventricle
Define
Superior Vena Cava
returns blood from upper part of body
Describe the function
Inferior Vena Cava
returns bld from lower body
Describe the function
Pulmonary Vein
carries Oxygenated bld from lungs to left atrium
Describe the function
Pulmonary artery
Carries Deoxygenated bld from right ventricle to lungs
Describe the funciton
Aorta
carries bld to left ventricle of body
first branches from aorta are the coronary arteries
