Summary
- The are a number of steps involved in the development of the human heart. These included the formation of the two endocardial tubes which fuse later into a single endocardial tube
- The cardiac skeleton consists of multiple layers, four chambers, four valves, cardiac septum and conduction system
- Coronary circulation is an integrated network of arterial, venous and collateral circulation as well as cardiac nerves and lymphatics
- Contraction (systole) and relaxation (diastole) plays an important role in maintaining the cardiac function and forms the basis of the cardiac cycle
- The regulation of cardiac muscle contraction is an integration of neural, hormonal and intrinsic components of the heart
- Depolarisation and repolarisation forms the basis of cardiac muscle cell function
