What are the four functions of the stomach?
The core function of the human stomach is as an aid to diges- tion.
The four key components of gastric digestive function are its function as a reservoir, acid secretion, enzyme secre- tion and its role in gastrointestinal motility..
What gland is in the stomach?
The cardiac gastric glands are located at the very beginning of the stomach; the intermediate, or true, gastric glands in the central stomach areas; and the pyloric glands in the terminal stomach portion.
What are the three main parts of the stomach?
The stomach has three anatomical regions:cardiac, which contains mucous secreting glands (called cardiac glands) and is closest to the oesophagus.fundus, the body or largest part of the stomach which contain the gastric (fundic) glands.pyloric, which secretes two types of mucus, and the hormone gastrin.

What are the 7 steps of digestion?
The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.
What does the stomach absorb?
The stomach absorbs very few substances, although small amounts of certain lipid-soluble compounds can be taken up, including aspirin, other non-steroidal anti-infammatory drugs, and ethanol.

What are the parts of the stomach?
Structure. There are four main regions in the stomach: the cardia, fundus, body, and pylorus (Figure 1). The cardia (or cardiac region) is the point where the esophagus connects to the stomach and through which food passes into the stomach.
What are the 12 parts of the digestive system?
The alimentary tract of the digestive system is composed of the mouth, pharynx, esophagus, stomach, small and large intestines, rectum and anus. Associated with the alimentary tract are the following accessory organs: salivary glands, liver, gallbladder, and pancreas.
What is the main function of the stomach?
Stomach. The stomach is a hollow organ, or “container,” that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process.
What are the two types of digestion?
Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion.
What keeps the digestive organs in their place?
mesenteryThe mesentery attaches your intestines to the wall of your abdomen. This keeps your intestines in place, preventing it from collapsing down into your pelvic area.
What are the 6 functions of the digestive system?
Chapter Review. The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.
What are the functions of the human digestive system?
The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.
