ANATOMY

Detailed explanation-1: -Like a balloon, the bladder’s elastic walls stretch to store urine. When urine is emptied out, the walls flatten together.

Detailed explanation-2: -The wall of the bladder is comprised of smooth muscle fibers oriented in multiple different directions. These smooth muscle fibers are collectively known as the detrusor muscle. This interwoven orientation provides the bladder with the ability to stretch in response to the presence of urine.

Detailed explanation-3: -Usually the bladder walls become thicker and then grow because they are overstretched. The condition is sometimes referred to by medical professionals as bladder hypertrophy. An enlarged bladder can be present from birth or it can occur due to an obstruction in the bladder, the kidneys, or the connecting ureters.

Detailed explanation-4: -The bladder expands when it fills up, like a balloon. Nerves in the bladder wall detect the expansion and send a signal to the brain, letting it know that the bladder is full. The urinary bladder can store up to 500 ml of urine in women and 700 ml in men.
