The pronephros is an early structure in the developing urogenital system that forms the rudimentary kidneys. It functions briefly during embryonic development before regressing, making way for the formation of more advanced kidney structures like the mesonephros and metanephros.

During foetal development, the ductus arteriosus connects the pulmonary artery to the aorta, allowing blood to bypass the non-functioning lungs. This structure is essential for foetal circulation in utero and normally closes shortly after birth, redirecting blood flow through the lungs for oxygenation.

The foregut, a primary segment of the embryonic digestive system, gives rise to several key organs, including the stomach, pancreas, liver, and gallbladder. It also contributes to the formation of the oesophagus, part of the duodenum, and the associated structures of the digestive tract.

The ureteric bud is a crucial structure in embryonic development, giving rise not only to the ureters but also to parts of the renal collecting system, including the renal pelvis, calyces, and collecting ducts. It grows from the mesonephric duct and interacts with the metanephric mesenchyme to form the functional kidney.
