  • Razvoj srca = Development of the heart
    Zorc, Marjeta ; Petrovič, Danijel, 1963-
    The cardiovascular system is the first major organ system that develops and starts functioning in a growing embryo, because diffusion alone can no longer supply it with enough oxygen and nutrients. ... The heart forms at the end of the third week from the splanchnic mesoderm as a horseshoe-shaped primordium. Bilateral cardiac tubes fuse in the midline, and the fused cardiac tube undergoes further S-shaped bending. The heart increases in size, and several chambers (two atria and two ventricles) and the conducting system are formed.
