what are the structures found in the right atrium
Superior vena cava Inferior vena cava Right auricle Pectinate muscle Fossa ovalis Coronary sinus (opening of…)
what are the structures of the right ventricle
Right atrioventricular (tricuspid) valve Chordae tendineae Papillary muscles Trabeculae carnae Pulmonary Semilunar valve Trunk of pulmonary arteries Right and left branches of pulmonary arteries
what are thee strutures of the left atrium
Left auricle
Pulmonary veins (openings of…)
Pectinate muscle
what structures are found at the left veentricle
Left atrioventricular (bicuspid or mitral) valve Chordae tendineae Papillary muscles Trabeculae carnae Aortic Semilunar valve
pectinate muscle is located in the atrium or ventricle
atrium
what holds the chordia tendinae to the ventricl
papillary muscles
pulmonary trunk sends blood to the
lungs
the pulmonary arteries are carrying oxygenated or deoxy blood
deoxy blood
the pulm veins carry deoxy or oxy blood
oxy blood
explain the passage of blood through heart
deoxy blood comes in to the right atrium by SVC and IVC
tricuspid valve
right ventricle
up the pulm trunk through the pulmonary semi lunar valve
to the lungs by pulmary artries (left and right)
back to theart via pulm veins
left atrium
through bicupsid valve into the left ventricle
up through the aortic semilunar valve
up the aorta and out to circualtion
how does blood enter the right atrium
SVC and IVC
what are the cardiac veins
great anterior small middle coronary sinus
what divides the iventricles
interventricular septum
what divides the atrium
interatrial septum
where are the openings of the coronnary rteries found
above the oartic semil lunar valves

what vessel branches directly off the subclavian a
internal mammary
what branches off the internal mammary
anterior intercostals
what are the divisions of the aorta
aorta
thoracic aorta
abdominal aorta
common illiac

begins at hiates (starts at diaphragm)
where does the common illiac a bein
begins at umbilicit
what arteries branche directly off the thoracic aorta
posterior intercostal aq
