Which Organ System Is Lined By Transitional Epithelium To Accommodate Stretching? (Solution found)

The innermost layer of the bladder is the mucosa layer that lines the hollow lumen. Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine.

  • Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine. Click to see full answer.

Which organ system is lined by transitional epithelium?

Transitional epithelium lines the organs of the urinary system and is known here as urothelium.

Why transitional epithelium is stretchable?

Transitional epithelium is stretchable and waterproof. The cells of transitional epithelium are highly keratinized and contain tight junctions or virtually impenetrable junctions, that seal together the cellular membranes of neighboring cells.

What structures contain transitional epithelium?

Transitional epithelium is found only in the urinary system, specifically the ureters and urinary bladder. When the bladder is empty, this epithelium is convoluted and has cuboidal-shaped apical cells with convex, umbrella shaped, surfaces.

What is the function of the transitional epithelial tissue?

The cells of the transitional epithelia are specialized to protect underlying tissues from the hypertonic and potentially cytotoxic effects of urine. The morphological features of the cells allow distension of transitional epithelium as the urinary bladder fills and stretches.

Why is transitional epithelium called transitional?

Transitional epithelium is a layer of cells that forms the mucosal lining of your ureters, a portion of your urethra, and your urinary bladder. These cells are called transitional because they can undergo a change in their shape and structure.

Why is the bladder lined with transitional epithelium?

Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine.

What is the shape of transitional epithelium?

Transitional epithelium is a stratified tissue in which the cells are all have a fairly round shape when the organ it lines is not distended (stretched out).

Where is transitional epithelium found in the body?

Transitional epithelia are found in tissues such as the urinary bladder where there is a change in the shape of the cell due to stretching.

Which type of epithelium lines alveoli and what is its function?

The alveoli are lined with a single layer of squamous epithelial cells, which allow for easy diffusion of vital gases.

Which urinary tubes are lined by transitional epithelium?

The ureter (one per kidney) is a long, straight, muscle-walled tube. The epithelium lining this tube is stratified, transitional epithelium.

Why the cells are in transitional epithelium differ in shape and can be stretch at certain extent?

Transitional epithelium is a stratified tissue made of multiple cell layers, where the cells constituting the tissue can change shape depending on the distention in the organ. When the organ is filled with fluid, cells on the topmost layer of this epithelium can stretch and appear flattened.

What cells are in transitional epithelium?

Transitional epithelium is an epithelial tissue which in a relaxed state appears as a stratified cuboidal epithelium. The cells in the transitional epithelium are pear-shaped or round, but as tissue is stretched, cells become flattened, giving the appearance of stratified squamous epithelium.

Where is transitional epithelium found in the body quizlet?

Transitional epithelium is found in the urinary system. It lines the ureters, bladder, and proximal part of the urethra–organs that are subjected to distention or stretching as urine passes through or fills them.

Which description is best for transitional epithelium quizlet?

Which description is best for transitional epithelium? Cells that are more cuboidal in a relaxed state but more squamous when stretched.
