How does most nutrient absorption occur?
The Small Intestine. The small intestine is the main site of nutrient absorption, and it is in fact the largest of the digestive organs in terms of surface area. The released products are absorbed into the circulation, along with water and electrolytes, via the specialized epithelial cells of the intestinal villi.

How are nutrients absorbed in the small intestine?
Villi that line the walls of the small intestine absorb nutrients into capillaries of the circulatory system and lacteals of the lymphatic system. Villi contain capillary beds, as well as lymphatic vessels called lacteals. Fatty acids absorbed from broken-down chyme pass into the lacteals.
How does absorption take place?
The process by which digested food molecules are absorbed into the bloodstream and transported to different parts of the body is known as absorption. Absorption of food begins with the small intestine. The digested food molecules pass through the walls of the small intestine and then into the bloodstream.
How are nutrients absorbed in the intestines?
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.
How are vitamins digested and absorbed?
Many fat-soluble vitamins travel through the body only under escort by proteins that act as carriers. Food containing fat-soluble vitamins is ingested. The food is digested by stomach acid and then travels to the small intestine, where it is digested further. Bile is needed for the absorption of fat-soluble vitamins.
What nutrients need to be digested before absorbed?
Most of the nutrients in the food you eat such as protein, fats, carbohydrates and fat-soluble vitamins need to undergo some amount of digestion before they can be absorbed.
