I feel so bad for my uncle, he had his kidneys fail and in order to stay alive, he needs blood dialysis three times per week, but they hook him up to the blood dialysis device and have all the blood in his body cleaned just like the kidneys do.
The blood dialysis device is essentially an artificial kidney as it performs close to the same functions.
Of course, the kidneys would do a slightly better work in determining what useful molecules in the blood should be reabsorbed by the body, if you want to live, you will need blood dialysis to keep you going until you can get a replacement kidney, then and trust me, the wait list for kidneys is long and oftentimes people are unable to get a replacement kidney, then my uncle is regularly so faint and he looks something like a ghost these days, he is so pale, I just hope that he can get his turn to get a kidney transplant. I would donate mine but we don’t have the same blood type. These days, he is regularly changing the temperature control settings in order to find a bit of comfort in his home. He uses a smart thermostat these days because he can’t just be walking over to the thermostat all the time, otherwise he would entirely choose to remain in discomfort because it is challenging for him to get around the house. With the smart thermostat, he actually just adjusts the temperature control settings on his phone as he keeps it with him regularly.
