Among the given options, the small intestine is typically the longest part of the human alimentary canal.
– The length of the small intestine in an adult human is usually about 6 to 7.5 meters (20-25 feet) when relaxed, although it measures shorter in a living body due to muscle tone.
– The stomach is a J-shaped organ about 25-30 cm (10-12 inches) long.
– The large intestine is about 1.5 to 1.8 meters (5-6 feet) long.
– The rectum is the final section of the large intestine, about 15-20 cm (6-8 inches) long.
– The small intestine is where most of the digestion and absorption of nutrients takes place, and its great length provides a large surface area for these processes, enhanced by folds, villi, and microvilli.
