Final answer:
The six organs of the gastrointestinal (GI) tract are the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. They play crucial roles in the process of digestion from intake to excretion.
Step-by-step explanation:
The six organs that make up the gastrointestinal (GI) tract are integral to the digestive system. These include:
- The mouth, where digestion begins with the mechanical and chemical breakdown of food.
- The pharynx, which is the passageway for food from the mouth to the esophagus.
- The esophagus, a tube connecting the pharynx to the stomach.
- The stomach, where food is mixed with digestive juices and begins to break down into a semi-liquid form called chyme.
- The small intestine, a long, coiled tube where most nutrient absorption occurs.
- The large intestine (colon), which absorbs water and electrolytes and compacts the indigestible waste into feces.
While there are accessory organs such as the liver, gallbladder, and pancreas that aid digestion, they are not part of the GI tract through which food directly passes.
The organs that make up the gastrointestinal (GI) tract are the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. These organs work together to break down food, absorb nutrients, and eliminate waste. The mouth, starting point of the GI tract, helps with mechanical digestion through chewing, while the stomach and small intestine perform chemical digestion. The large intestine absorbs water and forms waste into feces.
