Urinary System

The urinary system is responsible for the production, storage, and elimination of urine. It is made up of the kidneys, ureters, bladder, and urethra. The kidneys are a pair of bean-shaped organs that filter the blood and produce urine.

Urine is stored in the bladder until it is eliminated through the urethra. The urinary system helps to maintain the body's fluid balance, removes waste products from the blood, and regulates the levels of electrolytes in the body.

The kidneys are located in the abdomen, just below the ribs. Each kidney is about the size of a fist. The left kidney is usually slightly larger than the right one.

The ureters are a pair of tubes that carry urine from the kidneys to the bladder. The urethra is a tube that carries urine from the bladder to the outside of the body.

The bladder is a sac-like organ that stores urine. The bladder is located in the pelvis, just above the pubic bone. The pelvic floor muscles support the bladder and help to keep it from emptying too often.

The urinary system helps to maintain the body's fluid balance, removes waste products from the blood, and regulates the levels of electrolytes in the body. Urine is also a way for the body to get rid of excess water, salt, and other wastes.
