It’s the mucosa, not the submucosa.
What else can I help you with?
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 layer of the digestive tract is composed of stratified and columnar epithelium?
The layer of the digestive tract that is composed of stratified and columnar epithelium is the mucosa. This layer is responsible for absorption and secretion in the digestive system.
The layer of the digestive tract that is composed of stratified and columnar epithelium?
The layer of the digestive tract that is composed of stratified and columnar epithelium is called the mucosa. This layer is responsible for absorbing nutrients from digested food and protecting the digestive tract from harmful substances.
What layer of the digestive system wall is the innermost layer and protects the tissues of the canal?
the kidneysor the lungs
What are the sheets of peritoneal membrane that hold the digestive tract in place?
mesenterymesenteriesThe sheets of peritoneal membrane that hold the digestive tract in place are called mesenteries. The innermost tissue layer of the alimentary canal is the mucosa.
Do all parts of the digestive tract have a serosa layer?
no
Which layer of the digestive tract contains blood and lymph vessels and nerve cells?
The submucosa layer of the digestive tract contains blood vessels, lymph vessels, and nerve cells. These structures play important roles in providing nutrients, removing waste, and coordinating digestive functions within the gastrointestinal tract.
Is lumen a layer of the digestive tract?
No, the lumen is not a layer of the digestive tract; rather, it refers to the hollow space within the digestive organs where food passes through. The digestive tract is composed of several layers, including the mucosa, submucosa, muscularis, and serosa. The lumen is surrounded by these layers, playing a crucial role in the digestive process.
Which histological layer of the digestive tract is composed primarily of epithelial tissue?
The epithelial tissue is primarily found in the mucosa layer of the digestive tract. This layer consists of epithelial cells that line the inner surface of the tract, providing a protective barrier and facilitating absorption of nutrients.
What is the digestive walls?
The digestive walls refer to the layers of tissue that make up the gastrointestinal tract, which is responsible for processing food. These walls typically consist of four main layers: the mucosa (innermost layer), submucosa, muscularis (smooth muscle layer), and serosa (outer covering). Each layer has specific functions, such as secretion, absorption, and movement of food through the digestive system. Together, they facilitate the complex process of digestion and nutrient absorption.
Goblet cells are found in the layer of the digestive tract wall called?
mucosa
Which layer of embryonic tissue forms the lining of the digestive tract?
The endoderm layer of embryonic tissue forms the lining of the digestive tract. It gives rise to the epithelial cells that make up the inner lining of the gastrointestinal system.
