The first set of excretory organs that is rudimentary and nonfunctional.

The second set of excretory organs that may function briefly during early fetal development.

The definitive kidney that forms the permanent kidney by the fifth week of development.

Vestigial excretory units formed by the pronephros that regress before maturity.

An outgrowth of the mesonephric duct that leads to the development of the collecting system.

The dilated section formed by the ureteric bud that connects to the ureter.

Common developmental disorders of the urinary tract like horseshoe kidney or ectopic urethra.

The movement of kidneys during development affecting their final location.

The functional unit of the kidney responsible for urine formation.

A cup-shaped structure surrounding the glomerulus in the nephron.

Tubes that transport urine from the nephron to the renal pelvis.

A network of capillaries involved in the filtration of blood in nephrons.

A kidney abnormality characterized by non-functioning structures surrounded by undifferentiated cells.

The first segment of the renal tubule that reabsorbs water and nutrients.

Structures in the kidney formed by collecting tubules converging on the minor calyx.

A condition where one or both kidneys fail to develop, can be unilateral or bilateral.

Symptoms resulting from renal agenesis, including anuria, oligohydramnios, and hypoplastic lungs.

A condition where numerous cysts form in the kidneys, leading to dysfunction and potential renal failure.

A genetic disorder with cysts forming from collecting ducts; causes renal failure in infancy.

A genetic disorder where cysts form from all nephron segments, typically resulting in renal failure in adulthood.

Condition resulting from the early splitting of the ureteric bud, leading to two ureters.

The process where kidneys ascend from pelvic position to abdominal position during development.

The kidneys receive blood supply from pelvic aorta branches that shift higher as they ascend.

The epithelium of the urethra originates from endoderm in both sexes, while surrounding tissue comes from mesoderm.

The epithelium of the prostatic urethra proliferates during the 3rd month and leads to the formation of the prostate gland.

A condition occurring when the intraembryonic allantois lumen persists, allowing urine to drain from the umbilicus.

A rare defect where bladder mucosa is exposed due to failed closure of lateral body wall folds.

Occurs when a localized area of the allantois persists, leading to a cystic dilation due to secretory activity.

A kidney that fails to ascend and remains near the common iliac artery.

A condition where the lower poles of kidneys fuse during ascent, resembling a horseshoe.

Extra arteries that supply blood to the kidneys, often from the aorta.

The metanephros becomes functional around the 12th week, producing urine that mixes with amniotic fluid.

The cloaca divides into the urogenital sinus and anal canal during fetal development.

Divided into three parts: urinary bladder, pelvic part, and phallic part.

A fibrous cord that connects the bladder apex to the umbilicus after the allantois is obliterated.
