The children had two heads, two legs and two arms, sharing all the body below the neck. Each child had a separate spine, but shared a heart, liver, lungs and pelvis, and both brains functioned. The boys were featured on the Channel 4 programme Bodyshock on December 19, 2012, where it was reported they had died at six months.
In lower vertebrates, the pronephros is sometimes called the head kidney due to its anterior position behind the head. [33] In embryogenesis it is usually a transitional structure and is subsequently replaced by the mesonephros in most vertebrates. [7] In mammalian embryogenesis, the pronephros is usually considered to be rudimentary and non ...
In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organs [1] that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. [2] [3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres (4 + 1 ⁄ 2 inches) in length.
The genital tubercles of an eight-week-old embryo of either sex are identical. They both have a glans area, which will go on to form the clitoral glans (females) or penile glans (males), a urogenital fold and groove, and an anal tubercle. At around ten weeks, the external genitalia are still similar.
At this point, the two kidneys are still in the pelvis, and are therefore pretty close together, so close that it’s thought that some flexion or growth of the developing spine and pelvic organs essentially pushes them together, causing the lower or inferior poles of the kidneys to touch and fuse together, forming what’s called a fibrous ...

In the human urinary system there are two kidneys that are located between the dorsal body wall and parietal peritoneum on both the left and right sides. The formation of urine begins within the functional unit of the kidney, the nephrons. Urine then flows through the nephrons, through a system of converging tubules called collecting ducts.
