digestive system

• the small intestine consists of the duodenum, jejunum, and ileum
• the large intestine consists of the cecum, ascending, transverse, descending, and sigmoid colon.
• lipase digests fats
• nuclease digests nucleic acids
• Trypsin digests proteins
• amylase digests starches
• the gallbladder concentrates and stores bile
• Pepsin is a stomach enzyme that serves to digest proteins found in ingested food
• the 4 regions of the stomach are the cardia, fundus, body, and pyloric region
• parotid glands are the largest glands, mostly serous secretions
• submandibular glands secrete both serous secretions and mucin
• sublingual glands is mostly mucin secretions
• the oral cavity is both chemical and mechanical digestion that begins in the mouth
• the pharynx is the passageway for food and air from the mouth to the esophagus
• the esophagus moves to the stomach via peristalsis, and it has no digestive or absorptive functions
• the stomach is a temporary food storage and has both chemical and mechanical digestion, the creamy food mass becomes chyme
• the small intestine is where most of the digestion of food occurs
• the liver detoxifies blood and produces bile
• the gallbladder concentrates bile and stores it
• the large intestine eliminates waste from the body
