The stomach is protected from the hydrochloric acid by
epithelial cells, which secrete a bicarbonate substance that covers the mucosa.
Since the bicarbonate solution is alkaline, it neutralizes the hydrochloric
acid produced by parietal cells and subsequently results in formation of water.
Importantly, the consistent secretion of the bicarbonate solution is what
protects the stomach from the strong acidic environment.
Answer:
lagoon
Explanation:
As the estuary gets more and more sediments, the deposition of them is constantly on the rise, affecting the landscape and forming new geographical features. With the sediments constantly building up, they eventually cut off part of the water from the sea. They will form a closed pool-like feature, filled with water, and surrounded by sediments, cut off from the sea. It will have shallow water, and because the water is stagnant and shallow it will have higher temperature than the other water. This geographical feature is known as lagoon.
A) transports oxygen and carbon dioxide for the respiratory system
