digestive functions

1. keeps food from going the wrong direction through digestive system:
2. enzyme: chemical digestion begins with breakdown of carbohydrates:
3. rhythmic wavelike motion, propels food through digestive system:
4. semisolid food in esophagus:
5. liquified food in stomach:

Explanation:

These questions are about the digestive system's structures and functions, which falls under the subfield of Biology (a subfield of Natural Science). The questions ask for identification of organs, muscles, processes, and other anatomical and physiological aspects related to digestion.

Answer:

Let's answer a few of these (you can ask for more specific ones or all, but here are some examples):

1. Organ: small muscular sac that secretes bile, located in the upper right quadrant: Gallbladder
2. Sphincter muscle: between esophagus and stomach: Lower esophageal sphincter (Cardiac sphincter)
3. External opening of the large intestines?: Anus
4. Supports and protects teeth: Alveolar bone (Jawbone)
5. Another name for oral cavity: Buccal cavity
6. Food moves from the pharynx to the stomach by passing through this muscular tube: Esophagus
7. 3 salivary Glands: Parotid, Submandibular, Sublingual
8. Part of the small intestines receives bile from the gallbladder and liver: Duodenum
9. Three parts of the small intestine in order: Duodenum, Jejunum, Ileum
10. Tongue attached to floor of mouth and this bone: Hyoid bone
11. Feather - shaped digestive organ secretes enzymes to breakdown food: Pancreas
12. Parts of the large intestine in order: Cecum, Colon (Ascending, Transverse, Descending, Sigmoid), Rectum, Anus
13. Separates the mouth from the nasal cavity: Palate (Hard and Soft palate)
14. Specialized lymphatic vessels of the small intestine: Lacteals
15. Muscular organ that aids with chewing and swallowing of food: Tongue (and also the jaw muscles, but tongue is a main muscular organ here)
16. Organ detoxifies alcohol (drugs too): Liver
17. Helps direct food into the esophagus: Epiglottis
18. Chemical and mechanical digestion starts here: Mouth (Oral cavity)
19. Largest organ of the body: Skin (but in digestive context, Liver is a large digestive organ, but Skin is the largest overall)
20. Another name for baby teeth: Deciduous teeth
21. Number of baby teeth: 20
22. Number of primary teeth: 20 (same as baby teeth, primary teeth are baby teeth)
23. Another name for chewing: Mastication
24. Common passageway for air and food: Pharynx
25. Three areas of the stomach: Fundus, Body, Pylorus
26. Sphincter muscle: between stomach and duodenum: Pyloric sphincter
27. Where can microvilli be found: Small intestine (especially Ileum and Jejunum, on the villi of the intestinal lining)

Digestive functions:

1. Keeps food from going the wrong direction through digestive system: Sphincters (and also valves like the epiglottis for airway, but in digestive tract, sphincters like lower esophageal, pyloric, etc.)
2. Enzyme: Chemical digestion begins with breakdown of carbohydrates: Amylase (Salivary amylase in mouth, Pancreatic amylase in small intestine)
3. Rhythmic wavelike motion, propels food through digestive system: Peristalsis
4. Semisolid food in esophagus: Bolus
5. Liquified food in stomach: Chyme
