Question

Transitional epithelium occurs in:
A. Ureter
B. Urinary bladder
C. Urethra
D. All of the above

Answer 1

The urinary system is involved in the regulation of fluid balance in the body. Since the kidney is a part of the urinary system. It has several parts made of different tissue including the transitional epithelium which is made of stratified epithelial cells.

Complete Answer:
Today we will learn about Transitional epithelium, it is a tissue that is stratified in nature. It is made from multiple cell layers. Cells constituting this type of tissue can change shape which usually depends upon the distended in the organ. When an organ is fluid-filled, cells stretch themselves from the top layer of the epithelium to appear flattened. While it appears in cuboidal shape when the fluid pressure is low in any organ. It is a notable point that it is composed of 3-4 layers of cells. All its cells are deeply connected at the junction point.

We may also need to know about the process of the urinary system
- The urinary system consists of organs like Ureter, Urinary bladder, Urethra, and Kidney. The urinary system is responsible for eliminating bodily waste.
- Urine is formed inside the kidney while the ureters carry the urine away from the kidney to the urinary bladder and it is considered as a temporary reservoir of urine.
- The role of the urethra is to take urine outside of our body from the urinary bladder with the help of its tubular structure.
- There are two main reasons for the occurrence of the transitional epithelium in the urinary system.
- It tends to provide im-permeability towards the water and other molecules. The cells of epithelium are resistant to osmotic pressure.
- These tissues stretch themselves based on the pressure of the fluid on the organ.

Hence the correct option is option D. Transitional epithelium is a part of the complete urinary system.

Note: Urinary system consists of organs like Ureter, Urinary bladder, Urethra, and Kidney. The urinary system is responsible for eliminating bodily waste. The malfunctioning of the kidney may result in the accumulation of salts such as creatine in the blood leading to kidney failure. This can be treated via the process of dialysis or transplantation surgery.
