What are the 2 systems that act to regulate the heart activity? The parasympathetic nervous system functions in regulating heart rate through the vagus nerve with increased vagal activity producing a slowing of heart reate. The sympathetic nervous system has an excitatory influence on heart rate and contractlitiy ... two types of controlling systems act to regulate heart activity nerves of the autonomic nervous system increase or decrease the heart rate two types of controlling system act to regulate heart activity intrinsic conduction system or nodal system Cardiac cycle helps in the circulation of blood. It includes systole (contraction of cardiac muscles) and diastole (relaxation of cardiac muscles). The cardiac cycle is a normal activity of the human heart and is regulated automatically by the nodal tissues- sinoatrial node (SA node) and atrioventricular node (AV node ). The body's nervous system neurotransmitters and hormones regulate the sinus node and play a huge role in how the body regulates heart rate. Each contraction of the heart muscle regulates the flow of blood in the form of a pulse or heart rate. The pulse is measured in beats per minute. Spread within the muscle of the ventricle walls. Describe how the Intrinsic Conduction System Works. 1st the SA node (a tiny cell mass) starts each heartbeat and sets the pace. 2nd From the SA node the impulses spreads through the atria to the AV node to cause a contraction.
