How is it formed?
Urine is formed in the kidneys of a human being. The urine is passed from kidney to bladder through the ureters. The urine is stored in the bladder. On urination, it is passed from bladder to urethra followed by excretion from the body.
Step by step explanation-
Inside the kidney are present numerous cells called nephrons. Each nephron consists of a small tube called a renal tubule. When urea, ammonia and other waste materials combine, it forms urine and it passes through the nephrons and down the renal tubules of the kidney.
I have made this as short as possible for 5th standard students.
