Which type of circulation carries deoxygenated blood from the heart to the lungs?
Pulmonary circulation
Systemic circulation
Both
Neither
Which node is known as the heart's natural pacemaker?
Sinoatrial node
Atrioventricular node
Bundle of His
Purkinje fibers
Where are Purkinje fibers found and what is their function?
Purkinje fibers are found within the walls of ventricles; stimulation causes ventricles to contract.
Purkinje fibers are found in the atria; stimulation causes atria to relax.
Purkinje fibers are found in the sinoatrial node; stimulation causes heart rate to decrease.
Purkinje fibers are found in the pulmonary veins; stimulation causes blood oxygenation.
How is the conduction system of the heart visualized?
The conduction system is visualized as wave movements on EKG (or ECG).
It is visualized using X-ray imaging.
It is visualized by measuring blood pressure.
It is visualized through ultrasound scans.
Which part of the heart is known as the natural pacemaker?
Sinoatrial (SA) node
Atrioventricular (AV) node
Bundle of His
Purkinje fibers
