The urinary system
To understand how bladder weakness occurs, it helps to consider how the urinary system functions. This system consists of a number of interconnected structures whose job it is to make, store and excrete urine, one of the body’s waste products.
Sphincter – a circle of muscle around the opening of the bladder. Keeps urine inside and prevents leaks.
Pelvic floor muscles – surround and support the bladder and urethra. A strong pelvic floor helps prevent leaks.
Prostate gland – a small gland located between the penis and the bladder in men. It is involved in semen production, but if it becomes enlarged, it presses on the bladder and urethra, affecting urination.
