Body (corpus): The main part of the stomach, between the upper and lower parts Antrum: The lower portion (near the intestine), where the food mixes with gastric juice Pylorus: The last part of the stomach, which acts as a valve to control emptying of the stomach contents into the small intestine The first 3 parts of the stomach (cardia, fundus, and body) are sometimes called the proximal stomach. Some cells in these parts of the stomach make acid and pepsin (a digestive enzyme), the parts of the gastric juice that help digest food. They also make a protein called intrinsic factor, which the body needs to absorb vitamin B12.
A storage medium is the physical material on which a computer keeps data, instructions, and information. of bytes (characters) a storage medium can hold is its capacity. records and/or retrieves items to and from storage media.
A byte can also hold a string of bits that need to be used in some larger unit for application purposes (for example, the stream of bits that constitute a visual image for a program that displays images or the string of bits that constitutes the machine code of a computer program). byte is abbreviated with a B. (A bit is abbreviated with a small b.) Computer storage is usually measured in byte multiples. For example, an 820 MB hard drive holds a nominal 820 million bytes-or megabytes-of data.
