Answer 2

Villi that line the interior of the small intestine absorb nutrients from the liquid chyme that food consumption creates in the stomach.

• Little, finger-like projections known as intestinal villi (plural: villus) protrude into the small intestine's lumen.

• The small intestine's jejunum connects the duodenum and ileum at the middle of the organ.
• Its length is around 8 feet and 2.5 metres, and it has intestinal villi and circular folds that increase its surface area.
• In humans, each villus measures between 0.5 and 1.6 mm in length and has numerous microvilli extending from the enterocytes of its epithelium.
• These microvilli together form the striated or brush border.
• The small intestine is built to allow for nutrient absorption.
• The folds create a variety of tiny projections that protrude out into the lumen, or open area, of your small intestine.
• These projections are covered in cells that aid in nutritional absorption from the food that passes through.
• Microvilli: Tiny microvilli, which resemble small hairs, are found in abundance within the villi's cells.
