See your doctor.
The etymological origin of the word kidney is unclear. It is thought to possibly come from the Proto-Germanic *keudō ‎ meaning "sack, testicle".
could be an infection in sperm sac
According to the Mayo Clinic, testicle pain could be a result of a hernia, kidney stones, injury, blood vessel inflammation, urinary tract infection, or a variety of other causes. http://www.mayoclinic.com/health/testicle-pain/MY00464/DSECTION=causes
Could be. Your testicle might have drawn back up into your body, wrapped around your ureter and redescended. Please go to doctor NOW.This would be very unusual , but possible and potentially harmful.
The material that remains after reabsorption in the kidney is urine, which contains waste products, excess ions, and water that were not reabsorbed back into the bloodstream.
There are a lot of males who live a perfectly normal life with one testicle. They grow up, get married, and have children just like most other men. When you think about it, there are people living with one lung, one kidney, and/or one ovary. Some famous people with just one testicle are/were Lance Armstrong, Tupac Shakur, MLB players John Kruk and Mike Lowell, and Arnold Schwarzenegger.
maybe it could be that his testicle has been hit which is affecting his back or vice versa. Just a thought. 2nd Answer: Pain in those areas is common to a kidney stone "attack". It is also common to some very bad conditions which, if they persist for more than a day or two, should be looked at by a doctor.
The liquid that remains in the kidney after reabsorption is primarily urine, which consists of water, urea, electrolytes, and various waste products. The kidneys filter blood to remove waste and excess substances, reabsorbing essential nutrients and water back into the bloodstream. What is left, primarily in the collecting ducts, is concentrated urine, which is then excreted from the body.
The average size of a single kidney in an adult typically ranges from 10 to 12 centimeters in length and about 5 to 7 centimeters in width. When a person has only one kidney, the remaining kidney may undergo compensatory hypertrophy, potentially increasing in size to handle the body's filtration needs. Despite this, the average size remains similar to that of a normal kidney. Overall, individual sizes can vary based on factors like age, sex, and overall health.
The cells of the juxtaglomerular complex of the nephron. Granular cells in the kidney monitor alteration in blood pressure. If blood pressure falls and remains low, this specialized cells release the enzyme renin into the blood stream.
Logically speaking I don't see why not. If the kidney was originally harvested from a cadaver and implanted into the initial recipient and it was healthy and functioning at the time of the initial recipients death, then I'd say yes, it could possibly be transplanted to somene else as long as the tissue remains healthy and viable. **I hope I understood the question correctly...
If an animal has 40 chromosomes in its skin cells, it will also have 40 chromosomes in its kidney cells. This is because all somatic cells in an organism typically have the same number of chromosomes, which is characteristic of that species. The number remains consistent across different types of cells, including skin and kidney cells.
