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 side of epithelial faces the lumen?
Apical Border is the side of an epithelial cell that faces the lumen.
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.
Epithelial lining of the gastrointestinal tract is called what?
The lumen.
Absorption of glucose from the gut lumen depends on?
the sodium-potassium pump in the basolateral membrane of the epithelial cell, cotransporter proteins in the apical membrane of the epithelial cell, and higher sodium ion concentration in the lumen than in the epithelial.
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 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.
What is the involuntary tissue that constricts the lumen of the small intestine?
muscular tissue (specifically, smooth muscle)
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.
What is the difference between a polyp and a papilloma?
Polyps extend from the mucosa into the lumen of a hollow organ. Papillomas are epithelial tumors are project ouwards.
What is tunica interna?
It lines the lumen of the vessels, and is a thin layer of endothelium.
What is the function of simple epithelium tissue?
Tissues are groups of cells that lie together to accomplish a common function. There are four main types of tissues: epithelial, connective, muscular, and nervous. All of these tissues are found in our bodies, but epithelial tissue has a special function-- it must cover all the surfaces of the body. Therefore, it is found in our skin, and it is also found covering all the surfaces of the openings (each one is called a lumen) within our bodies.
