Starting from the 4th week, a septum begins to form within the primitive ventricle, giving rise to the interventricular septum. This structure is primarily muscular, but its upper section is completed by a thin fibrous portion known as the membranous septum.
This fibrous portion originates from the partitioning of the arterial bulb, which also gives rise to the pulmonary artery and the aorta, two of the main vessels in the circulatory system.

The cardiovascular system is the first to become functional in the embryo. As early as the third week of development, bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood circulation begins, marking a crucial step for the embryo’s growth and development. This primitive system ensures the delivery of nutrients and oxygen essential for its rapid development.

The circulatory system begins to form very early during embryonic development, just a few days after the fertilization of the egg by the sperm. It is the first functional system to develop, as it is crucial for delivering the nutrients and oxygen required for the embryo’s rapid growth. This early formation is a complex and fascinating process that marks the initial stages of life.
