Ureters

The ureters are muscular tubes that connect the kidneys to the bladder. Their main function is to transport urine from the kidneys to the bladder for storage and eventual elimination from the body. Each human has two ureters, one connected to each kidney.

Anatomy of Ureters

The ureters are approximately 25-30 cm long and about 3-4 mm in diameter. They extend from the renal pelvis of the kidney to the urinary bladder. Each ureter is composed of three layers: mucosa, muscularis, and adventitia. The muscularis layer consists of smooth muscle fibers that propel urine through peristaltic contractions.

Functions of Ureters

The primary function of the ureters is to transport urine from the kidneys to the bladder. The urine produced in the kidneys travels down the ureters to the bladder, where it is stored until it is eliminated from the body during urination.
