Most people know that they don't need their appendix, but what other organs can humans live without?

Humans are heartsruck because we have lost the vital symmetry of the ancients due to a lack of harmony. The problem might be regeneration of tissue whenever the need be has limits, eternity is for the divine....
Don't know what weird inferior schools YOU went to, but all the public schools in the USA, including all those I and my family went through, teach the why & how of everything as well as critical thinking.
All that knowledge and skills are lost when one gets a job. Jobs in the USA dumb everyone down. You lose all critical thinking skills, thanks to capitalism & extreme conservatism & hypocrisy of corporations & the governments that defend them.
My Dad was a victim of the 1953 polio epidemic (get your sugar cube vaccination, kids), and he was paralyzed from the neck down, requiring him to be in an iron lung for a long time till he regained his mobility. The iron lung was like a 12 to 14 ft. Can on its side wit a bellows at one end and a bed on the other end, with a hole for the patient's head to come out; Dad, like others who succumbed to polio, could not breathe on his own.
When Dad could breathe on his own, he was left with 1/5th of his lung capacity, which allowed him to live a long life —he was one of the longest lived epidemic survivors. He lived to raise 3 daughters, see his one grandson, and even take a travel vacation with Mom when he was about 60. He had complications along the way including heart failure, acidosis, and flat - lining, but his body compensated for the lung insufficiency by working overtime and over capacity.
I asked him once if it were possible to get a lung transplant, would he. He told me he might.
It was way after his death at 61 (40 years of blessed marriage) that I saw a TED talk of an opera singer who had sung her lungs into insufficiency, and she even had a few harrowing close calls when her equipment failed. She received a double lung transplant and her lungs gave her great power she never had before, though iirc she tempered her singing career (i.e. Not singing such high arias).
I'm sure that with today's medicine, if Dad had had a transplant of even one lung, it would have relieved his body tremendously so that he could live longer.
Thought I'd share.
I knew since my youth some (garble garble 40) years ago that livers grow back. I was interested in Ancient Greek mythology at the time, and the god Prometheus was chained to Mount Aetna for his irritating tricks against the Titans, and an eagle ate his liver every day, but it would grow back every night. He was condemned to this fate for eternity, till Heracles rescued him. Then I found out the human liver does have that regeneration capability.
But it didn't occur to me till now that liver cells might be the next candidate for pluripotent cells to create new body parts like stem cells are used for. I think the most difficult obstacle to surmount in transplants is rejection due to cell surface proteins. Pluripotency combined with DNA or RNA vectors (perhaps introduced by engineered viruses) could create proteins compatible with the recipient so the body would identify the transplant tissue as self tissue rather than rejecting it as alien tissue.
Just one small correction: the stomach doesn't actually absorb vitamin B12, it secretes a substance that facilitates the process, called the Castle factor. But the actual absorbing is still done at the small intestine level like most other nutrients.
My husband is living without a big chunk of his liver, his appendix, gallbladder, and 12 feet of small intestine (thanks, cancer...)
However, he’s totally kicking butt, working full time, and eating and digesting normal food! Our bodies are amazing :)
My grandmother had to have her gallbladder removed because of gallstones. She's still living a normal life, she just needs to watch what she eats, she basically can't have anything too fatty or else she'll feel really ill for a day or so.
My dad donated a kidney to his brother last summer. After the surgery my dad kept explaining to us how the kidney compensates for the other missing kidney, and how when they put the new kidney in they don't take the old one out.
Did you miss a button on your shirt? I’m pretty sure you forgot to button up your third button. I had to ask that. It goes with the video though. You can live while missing some organs. You can wear your shirt while missing some buttons.
When I saw the icon I thought it'd be about the extra organs people are often born with. Like accessory spleens or pancreases, or how 4 parathyrroid glands turned out to be a minimum rather than a set number.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
