Determine the primary function of the following system components.
Structure Function- What is the purpose of the body part?
1 Tongue- The primary function of the tongue is to mix food with saliva; the beginning of the process of digestion. It also is needed for verbal communication.
2 Submandibular gland The primary function of the submandibular gland is the production of saliva. It also contracts and expands depending on the amount of food entered.
3 Rugae
The primary function of the rugae is to increase surface area of the organ. This allows the stomach to expand when filled with food. The rugae of the oral cavity aids in bringing saliva into the oral cavity.
4 Cardiac sphincter The primary function of the cardiac sphincter is to prevent food from re-entering the esophagus. The cardiac and pyloric sphincters work together to keep food within the stomach to completely digest it.
5 Duodenum
The primary function of the duodenum is to produce mucus that aids in the process of digestion. The duodenum completes the digestion of carbohydrates, lipids, and proteins.
6 Omentum
The primary function of the omentum is to support and protect the stomach and small intestine.
