Certain sections of the gastrointestinal tract, such as the esophagus and parts of the stomach, have limited blood vessels to maintain their structural integrity and function. These areas rely on diffusion to receive nutrients and oxygen due to the presence of a thick muscular layer and the need to withstand mechanical stress. Additionally, the lack of blood vessels in specific regions helps prevent excessive bleeding during injury or trauma. Instead, these sections utilize surrounding vascularized tissues to support their metabolic needs.

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.
What kind of muscle is in the walls of tubelike structures?
Smooth Muscles line the walls of tubelike structure such as the gastrointestinal tract, the urinary system, the blood vessels and the bronchi of the lungs.
Which activity is most likely to be controlled by a smooth muscle?
A smooth muscle is responsible for the contractibility of hollow organs, such as blood vessels and the gastrointestinal tract. Going to the bathroom would be controlled by these types of muscles.
Where are sub mucosa found in the body?
The submucosa is a layer of tissue found beneath the mucosa in various organs of the body, including the gastrointestinal tract, respiratory system, and urinary tract. It provides structural support and contains blood vessels, nerves, and glands that contribute to the function of the mucosal layer above it. In the gastrointestinal tract, for example, the submucosa plays a crucial role in digestion and absorption.
What is found in the digestive tract and blood vessels?
white and red blood cells
What is smooth muscle activity responsible for?
Smooth muscle activity is responsible for involuntary body activities and the contractility of hollow organs. Hollow organs include the bladder gastrointestinal tract blood vessels, and the uterus.
What large vessel carries blood from the gastrointestinal tract to the liver?
Hepatic portal vein
What is the name of the circuit that supplies blood to the brain heart and gastrointestinal tract?
systemic circulation
Smooth muscle can be found in the walls of blood vessels and in the?
digestive tract
What is the use of pelvis?
Pelvis has many uses. It gives shape to the abdomen from lower side. It provide room for pelvic organs. It transmits weight of body to two lower extremities. It provides passage to gastrointestinal tract, urinary tract, sexual organs and blood and lymphatics vessels.
