The correct answer is C. Small intestine.
The small intestine is the longest organ in the human body, measuring about 20 feet long. It is located in the upper abdomen, below the stomach and above the large intestine. The small intestine is responsible for absorbing nutrients from food. It does this by secreting digestive enzymes and bile, which break down food into smaller molecules that can be absorbed by the bloodstream. The small intestine also has a large surface area, which increases the amount of nutrients that can be absorbed.
The gullet, or esophagus, is a muscular tube that connects the throat to the stomach. It is about 10 inches long in adults. The gullet’s job is to move food from the throat to the stomach. It does this by contracting and relaxing its muscles.
The large intestine is the lower part of the digestive system. It is about 5 feet long in adults. The large intestine’s job is to absorb water and electrolytes from food waste. It also stores food waste until it is eliminated from the body.
The stomach is a muscular sac that holds food while it is being digested. It is about 10 inches long in adults. The stomach’s job is to break down food mechanically and chemically. It does this by churning food and secreting digestive enzymes.
