7-The Heart_ Introduction and Origins

The heart plays a fundamental role in embryonic development, beginning its activity on the 21st day of intra-embryonic life. As the first functional organ, it is responsible for the distribution of information, directly influencing the growth of embryonic structures, particularly the neural tube. This interaction between the heart and the brain is essential, as the heart generates a pulsatile vibration that informs the central nervous system, thus establishing a vital connection for future development.

The heart is also involved in the nourishment and energetic support of the embryo, in connection with the digestive system and the endoderm. Through autocrine and paracrine mechanisms, it ensures the redistribution of essential nutrients, thus strengthening the bond between mother and child. This bond is particularly crucial during the first years of life, where the child still depends on the mother's health for their own development. At the age of seven, a significant transformation occurs, marking a stage of energetic and cognitive independence, where the child begins to assert themselves in their environment.

The primitive origin of the heart is found in the splanchnopleural mesoblast, and its asymmetrical position is determined by complex morphogenetic processes. The polarity induced by the spermatozoon and early cellular interactions establish an essential information field for cardiac formation. In summary, the heart is not only a vital organ, but a key player in orchestrating the first stages of life, influencing both physical development and the emotional and energetic connections between mother and child.
