In the two leaves experiment to prove how our stomach walls are protected, we use
grease or petroleum jelly and weak acid. With which parts of the body do we compare
these materials.
Answers
Answer:
Our stomach walls are protected with mucus with the action of hydrochloric acid (hcl) to activate the pepsin to digest proteins
Answer:
We compare these materials with the human digestive system.
Explanation:
Take two similar green leaves and apply jelly or Vaseline or grease on one leaf, while leaving the opposite because it is. Now, add some two to a few drops of weak acid to both the leaves and observe them after some half-hour. Observe which leaf was stricken by the acid. What are the changes that you simply observed on both the leaves? What saved the opposite leaf from the effect of acid? Mucus secreted by cells present within the walls of the stomach form a skinny lining on the walls and this counters the action on the stomach. Now, the function of the jelly will be compared to it of the mucus lining of the stomach wall. This proves that the stomach gets protected against its own acid secretions.
