HEART ANATOMY EXAM 1 2025 QUESTIONS
AND ANSWERS GRADED A+
Blood returning to the heart from the systemic circuit first enters the
Right atrium
The bicuspid or mitral valve is located
Between the left atrium and left ventricle
In this figure showing an anterior view of the heart, the left atrium is noted by
number
4
In this figure showing an anterior view of the heart, what is depicted by number 7
Right atrioventricular valve/tricuspid
The atrioventricular valve (AV) node is located in the
,Floor of the right atrium
The foramen ovale of the fetal heart is an opening in the
interatrial septum
Which prenatal structure forms the ascending aorta and pulmonary trunk
Truncus arteriosus
Which vein drains the posterior aspect of the ventricles of the heart
Middle cardiac vein
The function of the coronary sinus is to
take blood from the coronary circulation to the right atrium
The great cardiac vein runs alongside the
anterior interventricular artery
,The right border of the heart is supplied by the
right marginal artery
During ventricular contraction
The semilunar valves open and the AV valves close
What part of the cardiac conduction system is located in the posterior wall of the
right atrium, adjacent to the entrance of the superior vena cava
SA node
What is the sequence of events in the transmission of an impulse through the heart
muscle
c, d, a, b, f, g, e
Typically, there are papillary muscles that project from the wall of the
left ventricle and attach to the tendinous cords that support the left AV valve.
Two
, As blood is pumped out of the heart and into the major arteries leaving the heart, it
pushes against the semilunar valves and opens them
Identify the highlighted structure.
Papillary muscles
Which valve prevents the backflow of blood into the left ventricle when the
ventricles relax
aortic semilunar valve
How many half-moon shaped, pocketlike cusps are found in each semilunar valve?
3
Which action leads to the closure of the right atrioventricular valve
Contraction of the right ventricle
Identify the highlighted vessel.
