Why does walls of the stomach secrete hydrochloric acids?
Hydrochloric acid is secreted from the stomach because the enzyme pepsin, which breaks down proteins in the stomach, works best in acidic conditions. The acid also helps to kill any bacteria in the food. The hydrochloric acid is actually secreted from the pits in the stomach wall called gastric pits.
What substance is in your stomach which helps break down food particles?
gastric juice
What is the function of the mucus secreted by the mucous membrane of the nose?
They produce liquid secret rich with MUC6, and growing factors like TFF-1 and TFF-2, witch helps to stabilize mucous membrane. But the basic role of mucus neck cells is differentiation in chief cells, witch is stimulated by MUC4 interacting with c-ERBB-2 receptors.
What is the relationship between gastric juices pepsin and mucus?
Pepsin is an enzyme secreted in the stomach to break down proteins. Mucus on the other hand is produced in the nasal passages to help trap dirt and bacteria. The mucus is then transported to the back of our throats and into our stomach by the process of swallowing... mmm, tasty. *** Mucus protects the stomach from the gastric juices and hydrochloric acid (HCI). Pepsin is produced by the chief cells, and is turned into pepsinogen (by the hormone gastrin produced in the brain). Pepsinogen helps break down proteins in your stomach.
How are gastric juice and pepsin related?
gastric juice is secreted by the walls of the stomach and it contains pepsin and dilute hydrochloric acid. Pepsin helps in breaking down proteins into pep-tones or peptides during the process of digestion in the stomach.
Which of the following mechanisms helps prevent the gastric juice from destroying the stomach lining?
generation through mitosis of new cells to replace the stomach lining
What are the three substances secreted by various cell that are found in the with in gastric pit area of the stomach?
Acid, Mucus and Hormones. The hormones secreted by the stomach include proteases such as pepsinogen and prorennin. The acid is HCL (Hydrochloric acid). It helps in killing the germs, prevents the decay of food and also activates the inactive hormones into pepsin and rennin which help in the digestion of proteins. Mucus is secreted to protect the lining of stomach from corrosion due to the highly acidic HCL present in the stomach.
A chemical secreted by liver that helps in digestion?
Bile.
How does the stomach protect it self from being digested?
a simple way of answering this question would be that the stomach creates it's own acid that almost makes a protective layer on the inside of the stomach. this stops bad germs and diseases that come in through food/water from eating away at the stomach.
Mucous is the substance secreted by the mucous membranes?
believe it or not, mucous membranes secrete mucous. It helps protect the respiratory system (or whichever system the mucous membrane you're referring to is in).
Gastrin secretes what?
pepsinogen (a precursor of pepsin) which helps humans digest, when activated by HCL.
Why does your stomach have all 4 tissues?
the stomach needs the muscle tissue and the elastic tissue to stretch and digest the food. Connective Tissue: Is the blood in the walls of the stomach. Nervous Tissue: Controls acid production in the stomach. It also helps contract and coordinate stomach muscle. Epithelial Tissue: Protects the stomach against acid. It covers the inside of the stomach. It also has folds to increase surface area. Muscle Tissue: Mixes stomach contents and forces them towards the lower intestines. It is in between the epithelial tissue.
