The pancreatic juice, that is alkaline due to bicarbonate ions, neutralizes the acid contents of the stomach as they both enter the duodenum.
duodenum
Ozone molecules protect against UV rays. It is present as ozone layer.
To protect the intestinal wall against abrasion and irritation from the chyme. It also helps the particles of fecal matter together.
Mucus is secreted in the esophagus to provide lubrication and protect the lining from acidic stomach contents that may reflux back into it.
To protect the body.
The chemical that neutralizes the acidic chyme in the duodenum is bicarbonate. Bicarbonate is released by the pancreas to help neutralize the acidic chyme coming from the stomach. This helps protect the lining of the duodenum from erosion.
Substances that neutralize HCL in the small intestine include bicarbonate ions secreted by the pancreas, as well as mucus produced by the small intestine lining. These substances help raise the pH of the chyme (food mixed with stomach acid) and protect the intestinal lining from the acidic environment.
The duodenum needs to be alkaline in order to neutralize the acidic chyme coming from the stomach. This alkaline environment helps protect the duodenum from damage by the acidic content and provides an optimal pH for the enzymes that digest food to work effectively.
No, revolution does not protect against ticks.
The stomach is covered in mucus to protect it from the strong acids used to digest proteins. The duodenum (the very first section of the small intestine) does not have such mucus to protect itself. The pH change is crucial to make sure that the duodenum is not harmed by the strong acids from the stomach.
The substance secreted by the skin is called sebum, which is an oily substance produced by sebaceous glands. Its primary function is to lubricate and protect the skin and hair, preventing dryness and maintaining moisture. Additionally, sebum has antimicrobial properties that help protect the skin from pathogens.
It is secreted by epidermal cells to reduce evaporation of water and protect the plant from invading microorganisms.
