By the process of gastrulation, the embryo differentiates into three types of tissue: the ectoderm, producing the skin and nervous system; the mesoderm, from which develop connective tissues, the circulatory system, muscles, and bones; and the endoderm, which forms the digestive system, lungs, and urinary system.Mesodermal cells migrate from the surface of the embryo to fill the space.

The heart rate is established by the Sinoatrial Node (SAN) – the pacemaker of the cardiac muscle. In the absence of any influences the SAN pacing rate would be 100 bpm, however heart rate and cardiac output must be able to vary in response to the needs of the body. By influencing the cells in the SAN, nerve impulses and hormones can affect the speed at which the SAN generates electrical impulse.
