The hormones secretin and cholecystokinin which are released by duodenal enteroendocrine cells will have what overall action?

Expert Solution

Ans:-

Action of the secretin hormone:-

Secretin hormone is produced in the S cells of the duodenum which are located in the intestinal glands.

Action:-

Secretin helps in regulation of pH of the duodenum by inhibiting the secretion of gastric acid from the parietal cells of the stomach and stimulating the production of bicarbonate from the ductal cells of the pancreas.

Action of the cholecystokinin:-

Cholecystokinin is secreted from mucosal epithelial cells in the duodenum .

Action:-

It stimulates the gallbladder to contract and release stored bile into the intestine and stimulates delivery into the small intestine of digestive enzymes.

A) In the experiment, you have measured hormones Gastrin, Cholecystokinin (CCK), Gastric Inhibitory Polypeptide (GIP), Secretin, and Motilin over a 2 hour period following consumption of both meals. Describe any changes (i.e. increase, decrease or no change in hormone levels) following consumption of the two different meals (High Fat and High Protein). B) For the hormone(s) that were identified as increasing in response to the meal, explain: The mechanism(s) behind their secretion (i.e. what is the stimuli for their secretion)...

What hormones are responsible for the growth spurt during puberty? What cells do these hormones target and what is the action of these cells? Be clear and specific. Explain why there is a risk of stunted growth to a teenage male by taking anabolic steroids. Anabolic steroids mimic the effects of testosterone a sex hormone. Be clear and specific in the effect on bone growth. A post-menopausal woman will have a significant decrease in estrogen levels. Explain why this will...

2.What are hormones? 3.Most hormones circulate in blood and come into contact with essentially all cells. However, a specific hormone usually affects only a limited number of cells called _____________________________which contain receptors for that hormone. When hormones bind to receptors, it triggers a cascade of reactions within the cell that affects function.4.Endocrine glands secrete hormones directly into the bloodstream while exocrine glands release secretions through ducts into cavities or body surfaces. Some endocrine glands have other functions beyond hormone production...

Which of the following is true about interferon? It is released by uninfected cells during a viral infection It is produced by virally infected cells during a viral infection, whereupon it inhibits further viral replication within the cells where it is made. It is produced by virally infected cells to activate helper T-cells. It is released by virally infected cells to induce an antiviral state in uninfected cells. It is released by cells in lymph nodes to attract T cells...

1. Following an infection (or injury) in some tissue, __1__ are released by cells, which triggers a(n) __2__. One result is the recruitment of __3__, which is part of __4__. These cells engulf the __5__ in a __6__. This structure then fuses with a __7__ forming a complex structure called a __8__. Inside, the pathogen is __9__ and the remnants are expulsed as __10__. Some of the cells performing this task are __11__, which hold on to some pathogen remnants...
