## Step 1<br />The problem is a matching activity where we need to match each term with its correct definition. <br /><br />## Step 2<br />We start by matching each term with its corresponding definition.<br /><br />### ATP (adenosine triphosphate)<br />This is the primary source of energy for most cellular functions. It is often referred to as the "energy currency" of the cell.<br /><br />### Bile<br />This is a digestive juice produced by the liver and stored in the gallbladder. It aids in the digestion and absorption of fats in the small intestine.<br /><br />### Diarrhea<br />This is a condition characterized by the frequent expulsion of loose or watery feces. It is often a symptom of gastrointestinal disorders.<br /><br />### Feces<br />These are solid wastes that result from the digestion process. They are eliminated from the body through the rectum and anus.<br /><br />### Gallstones<br />These are small crystals that form from bile in the gallbladder. They can cause blockages in the bile ducts.<br /><br />### Gastric juices<br />These are digestive juices produced by the stomach. They contain hydrochloric acid and digestive enzymes that help break down food.<br /><br />### Gastrointestinal (GI) tract<br />This is a series of organs that play a role in digestion. It extends from the mouth to the anus and includes organs such as the stomach, intestines, and esophagus.<br /><br />### Kilocalorie<br />This is a unit of measurement used to express the energy value of food. It is commonly used to calculate the energy content of food and the energy expenditure of the body.<br /><br />### Mastication<br />This is the process of chewing food. It is the first step in the digestive process and involves the mechanical breakdown of food in the mouth.<br /><br />### Ulcer<br />An ulcer is an open sore that develops on the lining of the stomach, small intestine, or esophagus. It can cause pain and discomfort.<br /><br />### Disperse<br />To disperse means to distribute or spread out over a wide area.<br /><br />### Erratic<br />Erratic refers to something that is irregular or unpredictable.<br /><br />### Neutralize<br />To neutralize means to counteract or cancel out the effects of something.<br /><br />### Secrete<br />To secrete means to release a substance, such as a hormone or enzyme, into the bloodstream or into a body cavity.<br /><br />### Sloughed<br />To slough means to shed or remove the outer layer of something, such as the skin or a wound.
