urinestelsel

The urinestelsel, or urinary system, is a vital organ system in the human body responsible for producing, storing, and eliminating urine. This complex system plays a crucial role in maintaining fluid balance, regulating blood pressure, and removing waste products from the body.

The primary components of the urinestelsel include the kidneys, ureters, bladder, and urethra. The kidneys are a pair of bean-shaped organs located on either side of the spine. Their main function is to filter blood, removing waste products and excess water to form urine. This filtration process also helps to regulate electrolyte levels and produce hormones that influence red blood cell production and blood pressure.

From the kidneys, urine travels through two narrow tubes called ureters, which transport it to the bladder. The bladder is a muscular sac that stores urine until it is ready to be eliminated from the body. When the bladder is full, the urge to urinate is triggered.

Finally, urine is expelled from the body through the urethra, a tube that connects the bladder to the outside. The process of urination, also known as micturition, is a voluntary action controlled by the brain. The urinestelsel is essential for overall health, and its proper functioning is paramount for survival.
