@anatomygeek100 yeah? there are two sphincters in the anus btw… the internal sphincter is responsible for >70% of anal pressure, while the external sphincter provides voluntary control for defecation. the digestive system is how the body breaks down foods that are taken into the body. #winner

@anatomygeek100 what about the ileocecal sphincter? it controls the flow between the ileum and cecum… peristalsis also moves the food along the path that you mentioned. when the food reaches the rectum, the defecation reflex is triggered which will help with excrement. #anatomy #largeintestine

@anatomygeek100 how does each enzyme break down macromolecules though? wait, i know. bile mixes with fat globules to make smaller emulsion droplets, and the pancreatic enzymes break down carbohydrates. bile gets into small intestine thru common bile duct, enzymes get there thru pancreatic duct.

[anatomy lover @anatomylover4]

@anatomygeek100 what about all the enzymes secretes by the small intestine? you know, maltase and lactase? maltase turns the carbohydrates into simple sugar, while lactase turns lactose into glucose and galactose. this is the chemical digestion in the small intestine. #enzymeexpert

@anatomygeek100 well where does the stomach lead to, buster? the small intestine, duh. three major sections to it: duodenum (digests w bile and pancreatic enzymes), jejunum (absorbs water and nutrients), and ileum (absorbs vitamin B12). #ThursdayThoughts #competition

@anatomygeek100 do you know who you are talking to? i’m the enzyme expert. when HCl and pepsinogen come together in the stomach, the enzyme pepsin takes its active form. this enzyme breaks down protein in foods. this is the chemical digestion within the stomach. #ontop #enzymeexpert

@anatomygeek100 did you just blow in from loserville pal? you have to say what happens within the stomach, like the 4 sections of it? the fundus, body, cardia, and pylorus are the names. rugae also help to expand the stomach to fit more food in the stomach. #anatomygeek100sucks

[anatomy lover @anatomylover4]

@anatomygeek100 yeah? well bud you could try explaining the stages of deglutition for a start… starts with buccal (movement of food matter to orthopharynx), then goes to pharyngeal (orthopharynx to esophagus), then lastly, esophageal (esophagus to stomach).

@anatomygeek100 and also the chemical digestion that takes place with the salivary amylase secreted by the three salivary glands: sublingual, submandibular, and parotid. this serves to break down macromolecules with lingual lipase, turning proteins into easily digestible peptides. #anatomy

[anatomy lover @anatomylover4]

@anatomygeek100 yeah, you would only think that deeply of it. there are so many aspects to it you wouldn’t believe it, like how ingestion takes place and what that involves, stuff like mechanical digestion and the grinding of food matter by the teeth (mastication)
