How Long Is Our Intestine?

Have you ever thought about some questions about intestines? How long are your intestines? What are their functions? Intestines are the muscular tubes, extending from the stomach to the anus. These are parts of digestive system specialized for digestion and absorption of the food. Intestines are divided into two basic types: small and large intestines.

How Long Are Your Intestines?

When food is taken, it goes through the digestive system so that the body can absorb nutrients from it. The digestive system starts from the mouth and is followed by pharynx, esophagus, stomach and intestines, which are divided into two sections that have been mentioned above. Generally, the answer of the question “how long are your intestines?” is 7.5 to 8.5 meters (25 to 28 feet). Keep reading to find the detailed information about it.

1.     Small Intestine

The small intestine is a muscular tube about 6 to 7 meters (20-23 ft) in length. The average length of small intestine in adult males is 6.9 m (22 ft 8 in), and 7.1 m (23 ft 4 in) in adult females. However, it can vary from the shortest length of 4.6 m (15 ft) to the longest length of 9.8 m (32 ft). The diameter of small intestine is approximately 2.5–3 cm. The surface area of the small intestinal mucosa on average is 30 m².

The small intestine is made up of three segments, which form a passage from the stomach to the large intestine:

By the time the food enters the small intestine from the stomach, it is already converted into the semi fluid state called chyme. The small intestine receives between one and three gallons (6 to 12 liters) of this fluid on daily basis. The intestinal walls also produce the digestive juices containing enzymes along with liver and pancreatic digestive secretions to digest almost all parts of the food.

2.     Large intestine

Large intestine is wider than the small intestine but shorter than it. You will be curious about how long are your intestines? Then you must know"What is the length of the large intestine".The length of the large intestine is approximately 1.5 m (5 ft) and the diameter is 2.5 inches (6 to 7 cm), but it can become larger postmortem due to relaxing of smooth muscles. Large intestine is generally of 1.55 m length in women and 1.66 m in men.

The main job of the large intestine is to absorb water and salts. As the main part of absorption is already done by small intestine, the large intestine absorbs the remaining fibers (digested late) and undigested particles. It provides a passageway for the waste products like dead cells of GIT, undigested food materials, excessive salts, bile pigments (provide color to feces) and bacteria to be expelled out of the body. The helpful bacteria present in the form of fauna of the intestine also help in digestion and absorption of certain food materials. The usage of antibiotics kills these helpful bacteria, so the usage of curd is usually advised while using the antibiotic treatment. Large intestine consists of the following parts.
