<h3>What is pathogen?</h3>

The cell is called the Nucleus
The urinary tract is the body’s drainage system for removing urine, which is made up of wastes and extra fluid. For normal urination to occur, all body parts in the urinary tract need to work together, and in the correct order.
To urinate, your brain signals the sphincter muscles to relax. Then it signals the muscular bladder wall to tighten, squeezing urine through the urethra and out of your bladder. How often you need to urinate depends on how quickly your kidneys produce the urine that fills the bladder and how much urine your bladder can comfortably hold. The muscles of your urinary bladder wall remain relaxed while the bladder fills with urine, and the sphincter muscles remain contracted to keep urine in the bladder. As your bladder fills up, signals sent to your brain tell you to find a toilet soon.
