Adult Echocardiography

we assume all adults are 

normal 

the heart beats over

100,000 times a day

What is pulmonary circulation responsible for

circulating deoxygenated blood to lungs

what is the systemic circulation responsible for

pumping oxygenated blood to body

the heart lies in which cavity

thoracic

Anatomical relationship of hear to sternum

posterior 

what is the heart surrounded by

pericardium

what is at the tip of the left ventricle

apex

Where is the base of the heart

great vessels originate

The aorta originates from what ventricle 

left ventricle 

the pulmonary artery originated from the

right ventricle

The epicardium is the

outer layer of the heart

the myocardium is the

contractile layer of the heart

the endocardium is the

inner layer of the heart

which heart layer is in direct contact with blood

endocardium

what are the collecting chambers

the atria

what are the pumping chambers

ventricles

the right and left heart do NOT

communicate

what are the right and left atria separated by

interatrial septum

what atrium recieves oxygenated blood 

The left atrium 

what does the left atrium receive oxygenated blood from

the lungs

where does the left atrium empty blood

into the left ventricle

what atrium recieves deoxygenated blood

the right atrium

what does the right atrium receive deoxygenated blood from

the body and heart

where does the right atrium empty blood

into the right ventricle

what are the right and left ventricles separated by

interventricular septum 

are ventricular or atrial walls thicker

ventricular

the left ventricle wall is how many times bigger than the right ventricle wall

3 times thicker

the right ventricle moves deoxygenated blood into what

the pulmonary circulation

what ventricle contains the moderator band 

right ventricle 

The left ventricle moves oxygenated blood into what 

the systemic circulation 

How many atrioventricular valves are there

two

What are the two AV valves called

mitral and tricuspid

what side is the mitral valve located on

left

What side is the tricuspid valve on

right side

Where are the semilunar valves located

where the great vessels originate

The left side contains which valve

the pulmonic valve

the right side contains which valve

the aortic valve

what three structures dump deoxygenated blood into the right atrium

IVC, SVC, and coronary sinus 

The deoxygenated blood dumped into the right atrium then does what

moves across the tricuspid valve into the right ventricle

Path of blood from right ventricle

pulmonic valve, main pulmonary artery, right and left pulmonary arteries, lungs, pulmonary veins, and left atrium

pulmonary veins empty into what atrium

left atrium

Blood flow from left ventricle

aortic valve, aorta, sinuses of Val saliva, coronary arteries

What does electrical conduction system consist of 

SA node, AV node, bundle of Hid, and purkinje fibers

what node initiates atrial contraction

SA node

what node delays the SA pulse allowing the ventricle to fill

AV node

what carries electrical impulse to ventricles

bundle of His

what carries impulses to ventricular myocardium 

purkinje fibers 

what is the FINAL pacemaker

ventricular myocardium

what terms ventricular ejection of blood

systole

what terms ventricular relaxation/filling

diastole

while the ventricles are in systole the atria are

in diastole
