The wall of the urinary bladder in a fetal pig consists of several layers that facilitate its function in storing and expelling urine. The thickness of the bladder wall can vary depending on the developmental stage of the fetus, but it is generally thinner compared to the urinary bladder in adult pigs. The texture of the bladder wall is smooth and flexible, allowing it to expand and contract as the bladder fills and empties.
The inner surface of the urinary bladder is lined with a mucous membrane called the urothelium or transitional epithelium. This specialized lining is designed to protect the bladder from the potentially harmful effects of urine and maintain a watertight barrier. The urothelium is unique in that it can stretch significantly without losing its integrity, which is essential for accommodating the changing volume of urine.
I hope this helped!
