Gastric juice has a low PH of 2, and most would think why don’t our internal organs get digested due to the acidic juice that resides in our stomachs? This does not happen, because of all the cells lining our stomachs, along with a protective layer of a muscle that contains mucus that shield the lining of our stomachs. Why Aren’t Organs Digested with Stomach Acid? Animals do not digest their own internal organs due to specialty cells that are within our stomachs, like serosa, mucosa also including parietal cells, gastrin cells (g-cells) and epithelial cells. The digestive tract also produces a protective mucus that lines the stomach. The stomach stores food and begins digestion of proteins. During digestion, the stomach…show more content…
G-cells produce gastrin which is a hormone that enables the production the production of hydrochloric acid by the parietal cells. An animal’s stomach is protected by epithelial cells, which produce and secrete a bicarbonate-rich solution that coats the mucosa. The bicarbonate is a base that neutralizes the acid secreted by parietal cells, producing water in the process. Your stomach protects itself from auto digestion which is organs being digested by stomach acid, due to the continuous supply of bicarbonate. The inner surface of the stomach is lined by a mucous membrane, known as the gastric mucosa or epithelial cells. Mucosa is a thick layer of mucus that is secreted by epithelial cells. Unlike the gastric juices, the mucosa layer has a PH of seven (pH7) which is neutral. The gastric mucosa has six different layers of cells including the gastric mucosa or epithelial cells, the other five layers are mucoid cells, zymogenic cells also known as chief cells, g-cells, parietal cells, and endocrine cells. In conclusion, the stomach does not digest an animal’s internal organs, because the multiple layers of cells help protect the bodies from the acid released from the stomach. Our stomach being lined with serosa, mucosa, parietal cells, g-cells and epithelial cells help protect our internal organs from being digested... There is also a double layer of muscles that provide mucus, that have a PH of seven that protect the body of an
