What Is Urine and How It Is Produced ?
Urine is an excretory product produced by the kidneys and is passed through the ureters (tube) into the bladder. When the bladder becomes full, urine is expelled through urethra. When you eat and drink foods, the nutrients present in it are absorbed into the blood and other waste products are sent into the intestine. This would gradually pass into the kidney where urine and stool is produced from the waste food products. The nerve that controls the process of urination is complex and travels widely on your body reaching up to brain and spinal cord.
