We eat food composed of all the nutrients like carbohydrates. proteins. fats. vitamins. minerals and water. After digestion, these are absorbed in the form of glucose, amino acids. fatty acids, glycerol etc. What mechanisms are involved in absorption of digested food and water?

Hint: The small viscus consumes the bulk of the nutrients in your diet, that your circulatory system then distributes to different components of your body for storage or usage. Special cells assist within the passage of eaten nutrients into the viscus lining and into the bloodstream.
Complete answer:
Food interacts with digestive juices as it moves through the GI tract, allowing large food molecules to break down into smaller molecules. The body then absorbs these smaller molecules through the small intestine's walls and into the bloodstream, where they are distributed in the body.
Diffusion is a process in which molecules collide due to their kinetic energy and move from higher concentration to lower concentration. Osmosis is the movement of water molecules from a lower solute concentration to a higher solute concentration across a semipermeable membrane. Food that has been digested can enter the blood vessels in the small intestine wall.
Diffusion allows digested food to pass into blood vessels in the small intestine wall, and osmosis allows water present in the ingested food to be absorbed.
Diffusion and osmosis helps in absorption of nutrients.
Note:
Osmosis is the movement of solvents across a semipermeable membrane from a region of low solute concentration to a region of high solute concentration. Diffusion, on the other hand, does not require a semipermeable membrane to occur, and molecules move from a region of higher concentration to a region of lower concentration.
