Hydrochloric acid secretion by Parietal cells in stomach - Physiology Animations
Gastric acid, gastric juice or stomach acid, is a digestive fluid formed in the stomach and is composed of hydrochloric acid (HCl), potassium chloride (KCl) and sodium chloride (NaCl). The acid plays a key role in digestion of proteins, by activating digestive enzymes, and making ingested proteins unravel so that digestive enzymes break down the long chains of amino acids. Gastric acid is produced by cells in the lining of the stomach, which are coupled in feedback systems to increase acid production when needed. Other cells in the stomach produce bicarbonate, a base, to buffer the fluid, ensuring that it does not become too acidic. These cells also produce mucus, which forms a viscous physical barrier to prevent gastric acid from damaging the stomach. The pancreas further produces large amounts of bicarbonate and secretes bicarbonate through the pancreatic duct to the duodenum to completely neutralize any gastric acid that passes further down into the digestive tract.

Thank you 🙏

[@TheKrisz14]

Thank you so much that I don't need to read the book about it!

[@kashishsingh7467]

Thanks

[@mariociencia12]

Fantastic! However, the Na+ molecule is represented as H+. It is a minor error. The narration is correct. Thus, this little mistake do not compromise the experience of watching this magnificent video!

[@doctorbhanuprakash]

thank you we will correct it and repost , thanks for watching

Good

[@rajanibuddappagari4682]

"if we block the chloride ion channel, there is no secretion of hcl" this statement is correct or not

As someone who suffers from gastrointestinal reflux disease (GIRD), I have acid reflux all the goddamn time. I could eat a banana, and heartburn comes by to kill me.

[@rodrozil6544]

Seek medical help. it's dangerous.

[@UpInTheSky2025]

Hope you are doing ok, do you lay on your left side at night. Apparently this can help?

at 0:52, it says the hydrogen ion combines with the chloride ion. Does that actually happen? Hydrochloric acid is a strong acid, meaning that it completely dissociates in water. H+ and Cl- can form the molecule HCl in gaseous form, but does not exist that way in water.

[@spypipi2714]

Sir does parietal cell lie between the blood vessel and the lumen of stomach????

[@rubeushagrid4131]

How does the body know which chemical to produce ?

[@TheMaster47x]

How does HCl releases by the parietal cells make it past the mucus lining in the stomach?

[@UpInTheSky2025]

I dont know however I have a theory! Do you think it is because the Hydrochloric actually forms once it's passed the mucous layer? So the hydrogen and chlorine make its way through the mucous but once in the stomach it combines then cant enter mucous in this form. Again this is just a guess!

[@hibakhalid7850]

I love you ❤❤❤❤❤

[@rubeushagrid4131]

Where are the instructions for following this process in the body? How doesn these cells even know what to do to make that happen?

[@preeti806]

What happens to potassium ions 🤔

[@rajanibuddappagari4682]

Potassium ions are enter into stomach through potassium and chloride symport and it's reentered into the parietal cells for exchange of proton through proton pump

[@patelsaurabh8661]

Parietal cell ph is acidic or basic?????

[@andreid.824]

Parietal cell's ph is 7,02-7,20. So slightly acid.
