Development of the Cardiovascular 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.
