What is the function of valve Z?
to prevent the backflow of blood from the right ventricle to the right atrium
to prevent the backflow of blood from the left ventricle to the left atrium
to prevent the backflow of blood from the left atrium to the left ventricle

Electrical impulses pass from X to Y - what is happening to the heart at this time?
Diastole
Ventricular diastole
Ventricular systole
Atrial systole
During which stage of the cardiac cycle is Z closed?
Diastole
Ventricular diastole
Ventricular systole
Atrial systole
Name the type of blood vessel X
artery

The terms atrial systole, ventricular systole and diastole are concerned with
the cardiac cycle of the heart
the conducting system of the heart
the circulation of blood in the heart
cardiovascular disease of the heart
The terms sympathetic and parasympathetic are concerned with
the cardiac cycle of the heart
the conducting system of the heart
the circulation of blood in the heart
cardiovascular disease of the heart
Name the diagram that is produced from electrical activity in the heart
Electrocardiograph
Electrocardiogram

60bpm
83bpm
120bpm
100bpm
State the stage of the cardiac cycle that lasts longest.
atrial systole
ventricular systole
diastole
Predict how this ECG pattern would change under the influence of the parasympathetic nervous system
speed up
slow down
stay the same
Which statement about veins and arteries is correct?
Arteries can undergo vasoconstriction and carry blood at low pressure
Veins can undergo vasodilation and have valves
Arteries have a thicker muscular layer than veins and carry deoxygenated blood
Veins carry blood at low pressure and have a wider lumen than arteries
