Describe unique anatomical features that enable the stomach to perform digestive functions
Answers
Explanation:
The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
Answer:
The stomachis aJ-shaped organ that digestsfood. It produces enzymes (substances that cause chemical reactions) and acids (digestive juices). This combination of enzymes and digestive juices breaks down food to pass through your small intestine.
Your stomach is part of the gastrointestinal tract (GI). The GI tract is a long tube that begins in your mouth. It runs to your anus, where the stool (stool) leaves your body.The gastrointestinal tract is a key part of your digestive system.
Your stomach has five different stages:
Cardia is the upper part of your abdomen. It contains the cardiac sphincter, which prevents food from returning to your esophagus.
The fundus is a circular section near the cardia. It is under your diaphragm (a dome-shaped muscle that helps you breathe).
The body (corpus) is the largest part of your abdomen. In the body, your stomach contractes and begins to mix food.
The antrum lies beneath the body. Hold the food until your stomach is ready to send it to your small intestine.
The pylorus is under your stomach.Itincludes the pyloric sphincter. This tissue ring controls when and how the contents of your stomach move to your small intestine.
