Overview of the Cardiac Conduction System The cardiac conduction system is a network of specialized cells responsible for the initiation and co-ordination of the heartbeat. Relative to the myocytes responsible for regulating cardiac contraction in a normal heart (~1 × 109), the cells that make ...

Conduction System The heart is a beating muscle that continually pumps blood to the rest of the body. What we commonly call a heartbeat is actually the rhythmic contraction of the heart's four chambers. Each heartbeat is stimulated by electrical signals that travel through a specific pathway ...

Conduction System of the Heart Steps The main function of your heart’s conduction system is to contract and relax your heart, which causes your heart to beat and helps pump blood through your body. Each heartbeat is accompanied by electrical signals that travel along the conduction pathway. He...

This system functions as the body's own pacemaker and keeps the heart beating at a normal rate of 60 to 100 beats per minute. If the activity of this system is interrupted due to heart damage or other medical conditions, it can cause the heart to beat at an abnormal rate or with an ...

Explain the intrinsic conduction pathway that travels through the heart. Describe saltatory nerve conduction. Explain the need for saltatory conduction and how myelination and axon diameter affect the rate of conduction. a) What is the path that the conduction system takes? b) Which chamber does th...
Heart Blood Flow Diagram The heart is the primary engine behind one's circulatory system, or the system responsible for providing oxygen to the various parts of one's body. Generally speaking, the heart's right side receives deoxygenated blood and redirects this blood to the lung...
