Identify the structure(s) that make up the cardiac conduction system

With intrinsic regulation of the heart - the electrical impulse is generated in the:

After the impulse has been generated - the impulse travels across the atria walls to the:

The electrical impulse is delayed by about 0.09sec where?

There is a delay in the electrical impulse so that:

When the electrical impulse passes through the atrioventricular (AV) node, it moves to the:

After the electrical impulse passes the atrioventricular bundle (bundle of His), it moves to the:

After the electrical impulse passes the left & right bundle branches, it moves to the:

The cardiac conduction system does not rely on external stimulation

The electrical impulse within the cardiac conduction system is initiated by the:

Extrinsic regulation of the heart is influenced by the:

The Sympathetic Nervous System stimulates the pacemaker to:

The Parasympathetic Nervous System stimulates the pacemaker to:

A decrease in HR is brought about when the Sympathetic Nervous System releases acetylcholine

A decrease in HR is brought about when the Sympathetic Nervous System releases adrenaline (epinephrine)

An increase in HR is brought about when the Sympathetic Nervous System releases adrenaline (epinephrine) and norepinephrine (noradrenaline)

An increase in HR is brought about when the Parasympathetic Nervous System releases adrenaline (epinephrine) and norepinephrine (noradrenaline)

A decrease in HR is brought about when the Parasympathetic Nervous System releases acetylcholine

Which type of receptor would help us detect an increase in carbon dioxide levels in the blood brought about by exercise?

Which type of receptor would help us recognize that our muscles are exerting more effort than normal during exercise?

Which type of receptor would help us recognize an increase or decrease in blood pressure?
