Whether the pulmonary circuit is supplied by both the right and the left sides of the heart
True
Whether the systemic circuit contains oxygen-rich blood only.
False
Given a group of blood vessels, determine which one(s) belong(s) to the pulmonary circuit.
DO: pulmonary arteries and veins
The location of the apex of the heart relative to the midline of the body.
to the left of the midline
The names superior and inferior chambers of the heart.
superior: R&L Atriums
inferior: R&L Ventricles
The right atrioventricular valve (tricuspid) regulates the opening between what chambers of the heart
Right atrium and right ventricle
The heart valve(s) through which oxygen-poor blood passes through.
Tricuspid and pulmonary semilunar valves
The valve that regulates the flow of blood between the right ventricle and the vessels leading to the lungs.
Pulmonary semilunar valve
Where in the ventricles the chordae tendineae of the AV valves are anchored to.
The papillary muscles
The inflow of what ions results in the pacemaker potential.
Sodium (Na+) ions
The value of the heart rate if the SA node is damaged.
Reduced to 40-60bpm
The source of the Ca²⁺ needed for myocardial contraction.
Sarcoplasmic Reticulum
The cause of the first sound of the heart
Closure of AV Valves
The cause of the second sound of the heart
Closure of Semilunar valves
Defining the pulse pressure
difference between systolic and diastolic blood pressure
defining the stroke volume
amount of blood ejected by one ventricle during one contraction.
Defining bradycardia
a heart rate below 60bpm (slow heart rate)
defining cardiac output
volume of blood pumped by one ventricle per minute.
The value of blood pressure at the aorta and at the end of the vena cava.
highest at the Aorta and lowest at the end of the vena cava
The effect of cutting the nerve supply to the heart on the heart rate.
The heart rate would increase to the intrinsic rate of the SA node.
