The inner layer of the ureter is the mucosa. The mucosa consists of transitional epithelium and lamina propria. Lamina propria is composed of areolar connective tissue. The middle layer is the muscularis. This consists of smooth muscle. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. A portion of the outer layer is covered in serosa.

What type of tissue in the kidney tubules?
Transitional epithelium lines the lumen of the ureter. The transitional epithelium is a type of tissue that has multiple layers of epithelial cells that can contract and expand.
What side of epithelial faces the lumen?
Apical Border is the side of an epithelial cell that faces the lumen.
What tissue is described as an apical surface and a basement membrane?
The tissue described as having an apical surface and a basement membrane is epithelial tissue. Epithelial tissue covers body surfaces, lines cavities and organs, and forms glands. The apical surface is the top layer that faces the exterior or the lumen of a cavity, while the basement membrane provides support and anchors the epithelium to underlying connective tissue.
Which tissue is more apt to line a lumen?
Epithelial tissue is more apt to line a lumen due to its characteristic of forming continuous cellular sheets that provide a protective barrier. This type of tissue is found in organs that have cavities or spaces, such as the digestive tract, respiratory tract, and blood vessels.
What is the difference between apical and basal surfaces of epithelial tissue?
The apical surface of epithelial tissue refers to the top layer that faces the external environment or the lumen of an organ, often involved in absorption, secretion, or sensation. In contrast, the basal surface is anchored to the underlying connective tissue and plays a role in attaching the epithelial layer to the basement membrane. This structural distinction is crucial for the function and organization of epithelial tissues in various organs.
When epithelial tissue is a single layer its called?
The portion of the cell exposed to the lumen. The layer of plasma membrane on the apical side (side towards the lumen) of the epithelial cells in a body tube or cavity, separated from the basolateral membrane by the zonula occludens.- thefreedictionary.com
What kind of epithelial tissue is found in the heart?
== Epithelial tissue is located on the very outside of an organ or organism (i.e. skin) or found lining lumen (cavities in hollow organs (i.e. stomach lining). Epithelial tissue always has a free surface (no contact with another cell). Epithelial tissue is also avascular (no blood vessels) and must depend on underlying tissues for the nutrients and oxygen it needs to maintain homeostasis. For this reason, epithelial tissue is usually very thin. Another characteristic of epithelial tissue is that it has little to no intercellular matrix between it's cells. The cells are tightly packed together. Major functions of epithelial tissue include, protection, secretion, and absorption. And as another wiki person ID1342641670 said The epithelial tissue protects the main organ (the heart) from rubbing and damaging the lobes in the heart against the lungs it provides an extra barrier for security and saves the heart from injuries to the upper body around the heart area===
what is The layer of the digestive tract that secretes mucus into the lumen called?
The layer of the digestive tract that secretes mucus into the lumen is called the mucosa. This innermost layer is composed of epithelial tissue, connective tissue, and smooth muscle, and it plays a crucial role in protecting the digestive tract and facilitating the movement of food. The mucus secreted helps lubricate the passage of food and provides a barrier against pathogens.
What has a single layer of epithelial cells?
Simple Squamous epithelial cells are found in the lung (alveoli), lining the lumen of blood vessels, and lymphatic vessels, and also in the kidneys.
Where are apical lateral and basal surfaces of epithelial cells found?
Epithelial cells are structured with distinct surfaces: the apical surface faces the exterior or lumen of a cavity, often involved in absorption, secretion, or sensory functions; the lateral surfaces are adjacent to neighboring epithelial cells, facilitating cell-to-cell communication and adhesion; and the basal surface anchors the epithelial layer to the underlying connective tissue, providing structural support and a barrier between tissues. These specialized surfaces enable epithelial cells to perform their diverse roles effectively.
Double lumen PICC line colors and what they mean?
Double-lumen PICC lines come in two colors. Red is the blood access lumen or arterial lumen and blue is the blood return lumen or venous lumen. Despite the names, neither lumen is leads to an artery, but both lead into a vein.
Epithelial lining of the gastrointestinal tract is called what?
The epithelial lining of the gastrointestinal tract is called the mucosa. It is composed of specialized cells that help with absorption, secretion, and protection within the digestive system.
