Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
c. Smooth muscle of the stomach contracts when food enters from the esophagus.

검증된 단계별 안내

Step 1: Understand the role of smooth muscle in the stomach. Smooth muscle in the stomach is responsible for mixing and propelling food through the digestive tract via peristalsis and segmentation.

Step 2: Recall the process of food entering the stomach. When food passes from the esophagus into the stomach, it triggers the stomach's smooth muscle to contract, initiating mechanical digestion.

Step 3: Evaluate the statement provided. The statement claims that smooth muscle of the stomach contracts when food enters from the esophagus. Based on the physiological process, this is true.

Step 4: If the statement were false, you would need to correct it. For example, if the statement incorrectly claimed that smooth muscle does not contract, you would correct it to reflect the role of smooth muscle in initiating digestion.

Step 5: Conclude that the statement is true as written, and no correction is necessary in this case.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Smooth Muscle Function

Smooth muscle is a type of involuntary muscle found in various organs, including the stomach. It is responsible for the peristaltic movements that help in the digestion of food. When food enters the stomach, smooth muscle contractions facilitate the mixing and propulsion of food through the digestive tract.

Peristalsis

Peristalsis is a coordinated, wave-like muscle contraction that moves food through the digestive system. In the stomach, peristaltic contractions help mix food with gastric juices, aiding in digestion. This process is crucial for ensuring that food is properly broken down and moved along the gastrointestinal tract.

Gastrointestinal Response to Food

The gastrointestinal system responds to the presence of food through various mechanisms, including the release of hormones and the activation of smooth muscle. When food enters the stomach, it triggers reflexes that enhance muscle contractions, ensuring effective digestion and nutrient absorption. This response is essential for maintaining digestive health.
