DNES cell = enteroendocrine cell: manufacture endocrine, paracrine, and neurocrine hormones
Surface absorptive cells: tall columnar cells that function in terminal digestion and absorption of water and nutrients
Mucous neck cell: produce a soluble mucous that is mixed with and lubricates the chime, reducing friction as it moves along the digestive tract
Paneth cells: produce the antibacterial agent lysozyme
Crypts of lieberkuhn: ↑ surface area of intestinal lining
Brunner’s glands: produce a mucous, bicarbonate rich fluid as well as urogastrone (human epidermal growth factor)
Parietal cells: manufacture HCL and gastric intrinsic factor; both products released into lumen of stomach.
Chief cells: manufacture pepsinogen, rennin, and gastric lipase and release them into the lumen of the stomach.
Esophageal cardiac glands: produce mucous that coats the lining of the esophagus
