Final answer:
The tunics compromising the GI tube wall are the mucosa, submucosa, muscularis externa, and serosa.
Step-by-step explanation:
The tunics compromising the GI tube wall are the mucosa, submucosa, muscularis externa, and serosa.
The gastrointestinal (GI) tract, also known as the digestive tract or alimentary canal, is composed of several layers or tunics that facilitate the process of digestion and absorption of nutrients.
Understanding the layers of the GI tube wall is important for comprehending the processes of digestion, absorption, and motility that occur along the digestive tract. These layers work together to ensure the efficient and coordinated movement of food and the absorption of nutrients as it progresses through the GI system.
