Answer:
C. Esophagus
Explanation:
Esophagus:
The primary function of your esophagus is to carry food and liquid from your mouth to your stomach. When you swallow, food and liquid first move from your mouth to your throat (pharynx). A small muscular flap called the epiglottis closes to prevent food and liquid from going down the “ wrong pipe ” — your windpipe (trachea).
First, the teeth, tongue, and saliva turn food into a bolus, which is small and liquid enough to pass through the esophagus. Next, the bolus enters the stomach, where muscular action, acids, and enzymes turn it into a paste called chyme. The chyme enters the small intestine
Digestion
Food is actually pushed through the lumen throughout the digestive system by special muscles, and that process is called peristalsis. When you chew food and swallow, these are the structures in your body that the food goes through during its journey down to the anus:
Answer:D
Explanation: During the process of eating a meal, the bolus moves the oesophagus by the process of peristalsis down to the stomach where the meal mix stomach content(acid/base), turning the meal into a liquid form, moves to the small intestine for digestion. By digestion, the food nutrients is absorbed into the systemic circulation, while the fibre is moved into the large intestine for further digestion process and then excretion.
