Question

What is the length of the small intestine in an adult human being?
(a) 3.5 m
(b) 6.5 m
(c) 4.5 m
(d) 2.5 m

Answer 1

In an adult human being, the length of the small intestine is in between the number that corresponds to the atomic number of carbon and nitrogen. It is approximately 21.3 feet in length.

Complete step by step answer:
From the stomach to the large intestine, the small intestine runs. It continues the digestion process that began in the stomach.
In humans, the small intestine is the main component of the food canal. The small intestine is approximately 6.5 meters long in an adult human. It assists in food absorption and assimilation. For absorption and assimilation, longer intestines have a greater surface area.
Nutrients and water from digested food are consumed by the small intestine. Currently, 90% of the absorption of food occurs in the small intestine. Then what is leftover from this procedure is transferred into your large intestine.
Since it is so large, you can wonder why, in the first place, the small intestine is called "small." Currently, this word applies to the small intestine's width, which is around 1 inch (around 2.5 centimeters).
So, the correct answer is, ‘(b) 6.5 m’.

Additional information:
The small intestine actually has a very elevated surface area, considering its small diameter. That is because folds and hair-like projections literally cover the walls. This increased surface area allows for more nutrient and water absorption.
Around 1.5 meters long is the large intestine. There is also a greater diameter in the large intestine than in the small intestine. It has a width of around 3 inches (around 7.6 centimeters) .
The small intestine is divided into three sections, including the duodenum, jejunum, and ileum.

Note: The main component of our digestive system is the intestines. They are where most of the food vitamins and minerals are broken down in the bloodstream and consumed. The intestines do a lot of work to help provide you with the energy and nutrients you need to stay healthy, operate, and succeed every day. The total surface area of your intestines is around half the size of a badminton court, according to a 2014 report.
