and CORRECT Answers
Right atrium pressure (& what is considered high)? - CORRECT ANSWER - No
definition
anything over 8 mmHg


Right ventricle systolic pressure (& what is considered high)? - CORRECT ANSWER -
Pressure at the peak of systole
anything over 28 mmHg


Right ventricle end diastolic pressure (& what is considered high)? - CORRECT
ANSWER - Pressure at the end of diastolic, right before systole
anything over 9 mmHg


Left atrium pressure (& what is considered high)? - CORRECT ANSWER - No definition
anything over 12 mmHg


Left ventricle systolic pressure (& what is considered high)? - CORRECT ANSWER -
Pressure at the peak of systole
anything over 140 mmHg

Endocardium - CORRECT ANSWER - Innnermost layer of the heart which comes in
contact with the blood
Made of simple squamous epithelium and underlying connective tissue

,Myocardium - CORRECT ANSWER - This is the middle layer of the heart
Contains myocytes-which are responsible for heart contraction


Pericardium - CORRECT ANSWER - The outermost layer of the heart
Made up of two layers


Fibrous Pericardium - CORRECT ANSWER - Made of connective tissue and provides the
heart with stability by connecting to the sternum anteriorly and the diaphragm inferiorly


Serous pericardium - CORRECT ANSWER - This has two layers that consist of the
epicardium and the parietal layer


Epicardium - CORRECT ANSWER - this is the visceral layer of the heart and it lays
directly over the heart and contains the coronary arteries


Parietal layer - CORRECT ANSWER - Layer of the heart above the epicardium and
underneath the fibrous pericardium


Left ventricle - CORRECT ANSWER - -This ventricle is the larger of the two because its
workload is greater
-This ventricle pumps blood to the entire body and has a much higher afterload to push against
-This makes the pressure in this side of the heart greater than the other side


Right ventricle - CORRECT ANSWER - -This ventricle only pumps blood into the lungs
-The pressure in this side of the heart is lower than the other side


Umbilical vein - CORRECT ANSWER - This receives oxygenated blood from the
placenta
It connects to the hepatic circulation but also connects to the inferior vena cava by the ductus
venosus

, Ductus venosus - CORRECT ANSWER - This allows the oxygen-rich blood to enter the
vena cava and some blood does enter the hepatic circulation


Foramen Ovale - CORRECT ANSWER - This is an opening between the right and left
atria
This is where the most oxygenated blood in the right atrium is shunted through here into the left
atrium


One cardiac cycle - CORRECT ANSWER - This consist of one full contraction and
relaxation


Atrial kick - CORRECT ANSWER - When left ventricular relaxation and the left atrium
contracts to push blood into the left ventricle... it is called...


It increases the amount of blood put into the left ventricle and represents about 20% of the
cardiac output


Cardiac output - CORRECT ANSWER - -The amount of blood pushed from the left
ventricle in 1 minute
-Calculated by multiplying the heart rate in beats per minute by the stroke volume


Normal cardiac output - CORRECT ANSWER - 5L/minute



Stroke volume - CORRECT ANSWER - -The amount of blood ejected by the ventricle for
each cardiac cycle (heart beat)
-Highly dependent on the force of the contraction


Contraction - CORRECT ANSWER - This is dependent on the amount of preload which
stretches the left ventricle, the stimulation of endogenous positive inotropic agent (epi and
