It is possible to distinguish from three to five coccygeal vertebrae, fused together into a single coccyx. At the same time, the striation of the fused bone is visible, which gives an idea of ​​its initial discreteness.

The situation with kidney doubling is quite common. Even on both sides (a total of roughly four). Usually the third is significantly reduced in size and functionally weaker.

Organs with three lobes (glands) can also be noted.

No, it does not exist normally. Our body obeys the law of mirror symmetry: all organs lie in pairs on either side of the midline (lungs, kidneys, ovaries, etc.), or lie on the midline (brain, spine, heart, etc.). But a triple organ can be found in pathology, for example, a third kidney, with a complete doubling of the kidney from the discharge of a separate ureter.
