What else can I help you with?
Body secretions contain an enzyme called?
Body secretions contain an enzyme called amylase, which is responsible for breaking down starches in the digestive system.
Pancreatic digestive secretions regulated by what?
cholecystokinin
What do cholinergic drugs produce?
cholinergic drugs are to produce the same effects as stimulation of the parasympathetic nervous system. These effects include slowing of the heartbeat, increases in normal secretions including the digestive acids of the stomach, saliva and tears.
A structure that produces no digestive secretions of any kind is the?
duodenum
In which portion of the digestive system are there no secretions or digestion?
The large intestine
What 2 secretions does the pancreaus produce?
The hormone insulin and digestive enzymes
How might stress affect the digestive system?
When stressed, the part of the brain(central nevous system)responsible for the stimulation of the digestive ezymes to perform their digestive functions,will feel too weak and stressed to perform its function of stimulating the ezymes thereby given rise to constipation.
Does parasympathetic stimulation of the intestine increase or decrease motility and increase or decrease digestive gland secretion?
Parasympathetic stimulation of the intestine increases motility by promoting smooth muscle contractions and enhances digestive gland secretion by stimulating the release of digestive enzymes and fluids.
Does parasympathetic stimulation inhibit digestion?
No, parasympathetic stimulation actually enhances digestion. It promotes the release of digestive enzymes and increases blood flow to the digestive organs, which helps with the absorption and processing of nutrients from food.
Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
What part of the autonomic nervous system causes an increase in digestive tract mobility?
Stimulation of the Parasympathetic nervous system causes an increase in digestive tract mobility. When stimulated the parasympathetic post-ganglionic neurons release a hormone called Acetylcholine. This causes the Digestive tract to increase its contractions. Counteracting this increase in digestive tract mobility is the sympathetic nervous system, which releases a hormone called noradrenaline which slows down the digestive tracts contractions. This is how the Parasympathetic Nervous System gets the name "rest and digest"
Do all of the accessory organs of the digestive system send secretions to the small intestine?
Not all accessory organs of the digestive system send secretions directly to the small intestine. The pancreas, liver, and gallbladder do contribute secretions: the pancreas releases digestive enzymes, the liver produces bile (stored in the gallbladder), and both are delivered to the small intestine. However, other accessory organs, such as the salivary glands, primarily contribute to digestion in the mouth rather than directly to the small intestine.
