The image displays anatomical illustrations of the developing human heart. The top illustration, labeled (A) Dorsal view of heart, 26 days, shows the primordial atrium and its connections to various veins, including the left horn of the sinus venosus, left anterior cardinal vein, and left common cardinal vein. The right horn of the sinus venosus and the future superior vena cava are also depicted. Illustration (B) Dorsal view of heart, 8 weeks, presents a more developed heart, showing the aorta, pulmonary artery, pulmonary veins, oblique vein of the left atrium, and coronary sinus. Illustration (C) Internal view of fetal right atrium, further details the internal structures of the fetal right atrium, including the crista terminalis, sinus venarum, right auricle, and rough and smooth parts of the atrial wall. Illustration (D) depicts a schematic representation of the circulation in the thoracic cavity before birth, highlighting the higher pressure in the right atrium and lower pressure in the left atrium, with a shunt through the oval foramen. The septum secundum and septum primum are also indicated. Illustration (E) shows the circulation after birth, where the pressure in the left atrium is higher than the right atrium, and the oval foramen (oval fossa) is closed. The septum primum and septum secundum are again labeled. The text also briefly mentions patency of the superior part of the IVC in adults and congenital heart diseases such as Ventricular Septal Defects (VSDs).
