What is the correct sequence of organs involved in the digestive system?

The correct answer outlines the proper order of food movement through the digestive tract, starting from ingestion to the initial stages of digestion. The sequence begins with the mouth, where the process of digestion starts through mechanical chewing and enzymatic breakdown by saliva.

Next, the food passes through the pharynx, the shared pathway for both the respiratory and digestive systems. The pharynx leads to the esophagus, which is a muscular tube that transports food to the stomach through peristaltic movements. Following this, the stomach plays a vital role in further breaking down the food using gastric juices and churning motions. After the stomach, the food moves into the small intestine, where nutrient absorption occurs.

This sequence is crucial in understanding the physiological processes involved in digestion and helps in recognizing how food is processed through different organs. The correct order of these organs is foundational for students studying the digestive system and supports a comprehensive understanding of how the body functions.
