Cardiovascular System Flashcards
Learn Basic Cardiac Anatomy
Name the layers of the heart wall (Outer to Inner)
Pericardium
pericardial space
epicardium
myocardium
endocardium
What is the average heartbeat?
60-100 BPM
(Sinoatrial Rhythm)
What is the normal total output per min of the heart?
5L/min
How big is the normal heart? (size and weight)
size of a fist
weighs aprox 200 grams
What is the function of the heart?
pump blood to and from body tissues
Define and describe the function
Where is 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: inner-layer 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?
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?
Location of Purkinje Fibers
Inner layer
lines surfaces of the heart chambers and valves,

Name the Heart Valves
Tricuspid
Pulmonary semilunar
Mitral/bicuspid
Aortic semilunar
(Toilet Paper My Ass)
Name the chambers of the heart
Right atrium
Right Ventricle
Left atrium
Left ventricle
Where is the Tricuspid valve located?
Between right atrium and right ventricle
Where is the Mitral/bicuspid Valve located?
between the left atrium and left ventricle
Where are the Semilunar Valves located?
Base of the pulmonary artery & base of the aorta.
(prevent backflow)
Define
artery
Pushes blood away from heart
Define
vein
Pushes blood to heart
Name the Heart Vessels
Vena Cava
pulmonary artery
pulmonary veins
Aorta
Coronary arteries
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 blood from lungs to left atrium

Describe the function
Pulmonary artery
Carries Deoxygenated bld from right ventricle to lungs

Describe the funciton
Aorta
Carries blood to the left ventricle of body
First branches from the aorta are the coronary arteries

Name the Coronary Arteries
- LEFT Coronary Artery
- Circumflex Artery
- Left Descending Artery
- RIGHT Coronary Artery
