What digestive substances does the small intestine secrete?
The small intestine secretes enzymes such as amylase, lipase, and protease to break down carbohydrates, fats, and proteins, respectively. It also produces bicarbonate to help neutralize the acidic chyme from the stomach. Additionally, the small intestine releases mucus to protect its lining and facilitate the movement of food.
What is the name of the hormones that target other endocrine glands to stimulate their growth and secretion?
The names of the hormones that target other endocrine glands stimulate their secretions are tropic hormones. Most, if not all, tropic hormones come from the hypothalamus or anterior pituitary gland.
How do you pronounce chyme?
'Chyme' is pronounced as 'kime'.
What is the job of the bile when added after the stomach?
The food after being digested by the stomach forms chyme. Chyme is highly acidic, considering that the stomach has HCl of pH 1-2(interestingly, the stomach lining itself is changed every 2 weeks to avoid being damaged by the acid). If this chyme comes in contact with the lining of the intestine, it can severely damage the cells. Bile contains bile salts which are alkaline in nature. So its basic function is to neutalise the chyme.
What system of the body is the secretion of sweat controlled by?
The secretion of sweat is controlled by the nervous system. Specialized nerve fibers called sympathetic nerves stimulate the sweat glands to produce sweat in response to factors such as temperature, physical activity, and emotions.
What regulates discharge of CHYME into Duodenum?
The discharge of chyme from the stomach into the duodenum is primarily regulated by the pyloric sphincter, which controls the passage of partially digested food. Hormonal signals, particularly the release of secretin and cholecystokinin (CCK) in response to the presence of acidic chyme and fats in the duodenum, also play a crucial role. These hormones help modulate gastric emptying and stimulate the secretion of bile and pancreatic enzymes, ensuring optimal digestion in the small intestine.
What phase of the gastric secretion is chyme moved into the duodenum?
intestinal phase
Which substance neutralizes stomach acid as chyme enters the small intestine?
Bicarbonate is the secretion that neutralizes stomach acid as chyme enters the small intestine. Bicarbonate is necessary because chyme is highly acidic. Bicarbonate is created in the pancreas.
What stimulate gastric secretion?
Gastric acid secretion is regulated by hormones in the digestive system. This hormone, gastrin is secreted by the lining of the stomach.
When highly acidic chyme enters duodenum which hormone stimulates release of pancreatic secretion?
When highly acidic chyme enters the duodenum, the hormone secretin is released. Secretin stimulates the pancreas to release bicarbonate-rich fluids to neutralize the acidity of chyme coming from the stomach.
When chyme moves from the stomach into the small intestine the pH increases from 1 to 7 What is the secretion that causes this increase in pH?
The secretion that causes the increase in pH when chyme moves from the stomach into the small intestine is bicarbonate, which is released by the pancreas. Bicarbonate helps to neutralize the acidic chyme from the stomach, creating a more favorable environment for digestion to continue in the small intestine.
During the conversion of glycogen to glucose hormones are secreted to stimulate the secretion and they are?
Glucagons and insulin
Pancreatic enzymes digest compounds after they are secreted into the what?

Does diet effect pancreatic enzyme secretion? ... in human pancreatic enzyme secretion after 4 wks of oral pancreatic enzyme...
What do these pituitary hormones do to your body?
Promote growth control of protein, lipid and carbohydrate metabolism Stimulate secretion of thyroid hormones Stimulate secretion of glucocorticoids Have Milk production Control of reproductive function Conservation of body water Stimulates milk ejection and uterine contractions.
What are topic hormones?
These hormones stimulate the secretion of other hormones. Many hormones of hypothalamus are topic hormones.
When would bicarbonate and bile stimulated?
Bicarbonate secretion is stimulated primarily in response to the presence of acidic chyme in the small intestine, as it helps to neutralize stomach acid and create an optimal pH for enzyme activity. Bile secretion is stimulated by the presence of fats and fatty acids in the duodenum, which triggers the release of hormones such as cholecystokinin (CCK) that signal the gallbladder to contract and release bile. Both bicarbonate and bile are essential for proper digestion and absorption of nutrients.
What is the name of the secretion poured into the alimentary canal which contains no enzyme but helps in the digestion of fats?
bile
