Why do some of our organs come in pairs, such as kidneys, whereas we only have one heart, one liver etc?If an intelligent marine species like the octopus evolved to live on land, what is the likelihood it would develop

Because that’s the environment we are made from and for…..
Therefore, organ function determines if these will be single or double. This is also confirmed by the cybernetic system approach of traditional Chinese medicine. Alain de Bavelaere MD
side of the body will predominantly interact through the nervous system with the right hemisphere, as observed. The liver will interact with the left hemisphere. Double organs will exchange in sequence with both brain hemispheres.
complementary functions. These oscillations alternate in time from one hemisphere to the other thus influencing and regulating downward structures placed on the opposite side of the concerned hemisphere. Consequently, a unique organ, such as the heart, situated on the left
Answer in a nutshell: The brain and body are constantly interacting in many ways but also through oscillations. These play an important role in maintaining coherence in the whole organism. The oscillations of the brain are hemispheric; each brain hemisphere fulfills different,
A: in case we (USA) ever elect a deadbeat President,.. a 'spare of a pair' allows us to pawn $$ organs that we can do without-- iow- great insurance against runaway inflation
It must be a surface area thing. Both lungs and kidneys need a large surface are to be effective, whereas the heart actually needs the blood to be in a smaller area/volume to pump effectively. The stomach and liver also need all the food in one place to break it all down.
It just looked better on the plans
A genitic studder?
Like this heart is a very special organ to live, to love we say, just love whole heartly! Will it be wrong if we say just love whole brainly? Not good, we just see our soul also in our heart, that's so pure and spiritual.
As for all creatures that's mandatory, thanks to the one who built the lives perfectly and giving right things to live. If someone does not have one of pairs organ we called handicaped or I'll person, but surprisingly no one tell you I'll if you have one heart!
Because one liver and heart are enough for absorbing and delivering required oxygen and nutrients to our body but we require two kidneys, two lungs, etc. to get rid of the internal as well as external wastes that we receive these days (you know what I mean).
And we all have two mouths too. Ass and mouth. We all talk out of our asses
Because that is what what God plained for human being 👍
Animal life became mobile once it tamed spin of the earth. Brain is gift of spin of earth. Information gathering 2 eyes, 2 ears Blooded animals created one pump 2 lungs, 2 kidneys as the optimum system. The digestive system is a tube to which are attached secretion glands. 1/2
So that if one organ stop functioning,the other organ will continue to function supporting life.
Organs come in pairs because there are two of them. The ones that are on their own is because we have only one of them. QED

Because kidneys are cowards
Because that is what the instruction manual says. Genes that favor redundancy in critical systems were selected by evolution. Those with one lung and one kidney never made it long enough to reproduce with their one testicle 😂.
Organs are selected by nature if they give an advantage to outcompete competitors in reproduction. The number of organs are energy costly, so that, e.g. having three eyes is not doing the work much better than two to hunt or flight. So two-eyes organism are selected. Efficiency.
The reasons why some organs come in pairs and others do not are complex and multifactorial, and reflect a combination of function, size, symmetry, and evolutionary history.
Lol just in case one is lost, but over all it’s to ensure we get capacity filtration and reproduction and hear and see survival primal needs
They are fed with polar opposite blood coming from a centerfuge of the heart with opposite directional output. Think planet and magnetic field. It's simply an observation.
We're not Klingons
Somos organismos con simetría bilateral
Because it’s all about symmetric design. We have “two” of many organs to administrate work but also to protect in case of an accident. In organs like the heart, the symmetric design is inside. Anyway the brain sees being a human as a whole, not as organized organs.
Cuz it's a circuit board. Learn more at
Think of intelligent design. Pure functional efficacy with freewill power. Or humans would still be dragging a useless tail behin them! Neural pathways & habits after a few millions of years does it (or we wouldn't have a biospheric crisis of today)!
Because a heart can be lonely. Don't you agree?
Many organs would end up competing with each other. One of the ones we have is enough.
Evolution can be baffling at times! although I think that two brains might have helped a lot of people these days because the world situation etc etc
cells are dumb
Sometimes it’s more efficient to split the task, add redundancy and reduce complexity so that you can reduce cost.
The paired organs are for redundancy, where the cost/benefit justifies the duplication. Single organs are too 'costly' to maintain a duplicate - like the heart or the brain. The 'cost' in this context refers to energy and/or other resources consumed.
According to the requirements the body organes are present like Kidney filters blood and to filter approx 5L blood it is two while the Liver has main role like to form Bile and Detox the liquid of body but role is less so it is one and according to size it is of Big size
That is how god is. The Bible say that he made men at his likelihood. So, a defected animal
I just thought how strange it would be to have a pair of brains
Natural selection. Nothing more. Nothing less.
Because scientifically they feel lonely 😂😂😂😎
Please let me known the answer. 🤞
Some organs are loners
the heart is bicameral and the digestive system is just a waste drain we also have two brains but they’re so close together we can’t tell
So that others who may need one can have it. Nature is most generous.
some organs, such as the heart and liver, are large and complex and perform essential functions that cannot be replicated by a second organ. These organs also require a significant amount of blood flow to function properly, which can be challenging to maintain if there were two
Because of the process of cleaning and expelling toxins, the first kidney works on cleaning and the other on metabolism and filtering what remains
My guess is that either a single kidney or lung would be too bulky to fit, or that each of the pair does something slightly different... that we haven't discovered yet.
Most animals on Earth with brain have 2 eyes+1 mouth, except spider=8 eyes When come in pairs 2 organs work=👍corporate or👍independent 1 organ can send '1 signal'= in more conclusive to brain for decisive, without fights 2 kidneys=like freeway X 2 1 heart, liver =1 train station
Lack of spacial awareness on God's part
Wow, some people talk absolute bollocks.
I'm in two minds whether to respond to this..
We were given one heart to discourage polygomy.
It is what it is - Lukespl
Mechanics, it has to do a great deal with it. How woud you ride a bike with one pedal? How about waking with one leg?
I have 3 kidneys
Only the God knows
Random chance regulated by real-world utility. That is what evolution is.
Dr Who has two hearts ✌️ you’re welcome
For symmetrical functioning there are pair organs however heart and has its own chambers and liver has bile dict to support their func.
Why do we have 2 eyes 2 lungs 2 ears and 2 feet 2 legs. We evolved this way from water to land bipedalism.
To make a clear sign that when it not in pair it control the whole system in the body, and if that only one organ stop, the body die and if it's in pairs it means only support system. Cheers !
Of course, ChatGPT gives an explanation: …organs that come in pairs are typically symmetrical and perform functions that benefit from redundancy; organs that exist as a single structure are often more complex and require a centralized organ to perform their intricate functions
Let me try it first: the solar system in which humans live on Earth is a single star system. It can be corroborated by many astronomical phenomena we have discovered. The distribution and shape of human organs also subtly cater to these evidences.
competition of pseudoscience?
Imagine you had two penises and two ass holes world would be even worse place to live. Joke aside it might be for better functioning.
The organs we have one of seem to be those connected to the digestive system: stomach, spleen, pancreas, liver, appendix. These have all developed from the single tube running down the middle of early vertebrate bodies.
Bilateral symmetry was established very early on in evolutionary developmental pattern formation.
心肝宝贝
I would imagine it partly depends on whether an organ evolved before or after bilateral symmetry
The reason for a particular organ being paired or singular may depend on its specific function and needs. 1.Organs that required a little more surface area to carry out physiological functioning and yet fit in a compact anatomical human skeletal cage would elvove as such.
This is really an interesting question. Let me think about what would be a humorous answer.
so that I can tell whats normal form an individual when I’m examining them 😂
We have pairs of things, where redundancy would save our life. We have singles where had we had two, it would not help. So for example, if we had two hearts and we sprung a leak on one (or at any major artery), we would die anyway as the other would pump the blood right out ...
Because evolution is an ongoing process.
Body balance reasons
Natural selection; one heart don't need to be synchronized, liver repairs itself and even regrows, kidneys have other kind of failure proof than the liver. Mammals may face physical attacks by others: injuries have been common and those with better redundancy have survived.
Evolution
Those pairs of organs are Gods ways of giving us second chances. If we loose one eye we can use a second one, same goes to other pairs of organs. Why one heart?❤️ I believe we only have one life to live. Stay blessed 🙏🙌🥰
Organ which are to supply wholesome are one and are in pair to balance body, mind and soul feelings to upkeep,its Aura and distance to be symmetrical.
That's the biological arrangement in mammals.
