GENERAL HISTOLOGY

Detailed explanation-1: -Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through. Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli.

Detailed explanation-2: -The jejunum is the midsection of the small intestine, connecting the duodenum to the ileum. It is about 2.5 m (8 ft) long, and contains the circular folds, and intestinal villi that increase its surface area. Products of digestion (sugars, amino acids, and fatty acids) are absorbed into the bloodstream here.

Detailed explanation-3: -The small intestine is a long tube-like organ with a highly folded surface containing finger-like projections called the villi. The top surface of each villus has many microscopic projections called microvilli.

Detailed explanation-4: -These are found in the small intestine’s inner walls. Functions: Villi enhance the absorption surface area.

Detailed explanation-5: -Every cell lining the small intestine bristles with thousands of tightly packed microvilli that project into the gut lumen, forming a brush border that absorbs nutrients and protects the body from intestinal bacteria.
