The reason for this reality is that small intestine is very long, can use its muscular contractions to propel and mix food, it has villi and microvilli that improves the surface area for absorption, and receives and shelters digestive enzymes and bile which contribute to the food breakdown. In adults, the small intestine, unlike other GI tract organs, has an average length is about 23 feet. Food takes nearly eight hours to completely pass through this organ. This guarantees that there is sufficient duration for absorption to happen (Sauvanet, Wayt, Pelaseyed, & Bretscher, 2015). Second, unlike other GI tract organs, small intestine has villi and microvilli packed inside its walls, with a network of fine lymphatic vessels and capillaries. These features help increase the surface area of small intestine, for absorption to take place (Grant et al., 2015). A larger surface area increases the rate of absorption of nutrients from the lumen of the intestine into lacteals, which are surrounded by capillaries (including lipids) and capillaries (including carbohydrates and amino acids). The villi consist of a thin surface layer that appear above the capillaries that are linked to a blood vessel. Digested nutrients are absorbed into the blood vessels in the membrane of the intestine via diffusion process. Below is the depiction of the intestinal villus. Figure 1: Image of intestinal villus as depicted by (Sauvanet et al., 2015). Additionally, small intestine is surrounded with smooth muscle tissue, which allow for muscular contractions. Particularly, these muscles undergo a process known as peristalsis, a wavelike muscular contraction that helps move food via the small intestine (Grant et al., 2015). Such contraction also facilitates the absorption of the digested food through this organ. Moreover, small intestine is fed by different enzymes. The bile from the gallbladder and pancreatic enzymes join the small intestine and split nutrients, making them ready for absorption into the bloodstream. The absorbed nutrients are then conveyed through the blood vessels to different body organs in which they are applied to form proteins needed by the body. References Grant, C. N., Mojica, S.
