Why do we have two kidneys and two lungs?

Evolutionary anthropologists guess that we have two limbs, two lungs and two kidneys because these dual organs gave our ancestral organisms some kind of advantage, not because they’re spare parts We can see with one eye (and one-eyed organisms evolved first), but two eyes offer the advantage of depth perception.

Why do we have two kidneys when we can live with only one?

Sometimes our kidneys stop working. When this happens our blood cannot be cleaned and we can get very sick. After the new kidney is put into the recipient, both the donor and recipient only have one kidney that works properly. Both the donor and the recipient can live long happy lives with only one kidney.

Why do most people have two kidneys?

Most humans are born with two kidneys as the functional components of what is called the renal system, which also includes two ureters, a bladder and a urethra. The kidneys have many functions, including regulating blood pressure, producing red blood cells, activating vitamin D and producing some glucose.

Can a woman with one kidney have a baby?

However, as many as 1 in 1,000 infants are born with only one functioning kidney. In the past, most individuals did not know they had one kidney, and did not have any health issues. Today most women have an ultrasound during their pregnancy and most infants with a single kidney are discovered before they are born.

Why do we have two eyes and two ears?

For some organs, the function is really dependent on having two: two eyes offer the possibility to appreciate distances, two ears to appreciate directionality of sound and to balance oneself.

Why do some organs have two pairs of organs?

Scientists believe (as do we) that having pairs of organs is not just a sign of redundancy. In other words, having a pair does not mean that the body is keeping a ‘spare’. In fact, almost every organ pair is equally important to proper functioning of the body.

Why don’t we have two brains?

This is because the body re-organizes the functions of the rest of our body parts to be in sync with only one hand, rather than a pair. This is probably the reason why people with amputations develop unusual strength in their other hand. Since the body already functions at 100\%, it wouldn’t make much of a difference if we had two brains.
