transportation. The small intestine is responsible for absorbing nutrients from digested food, while the blood circulates throughout the body to deliver these nutrients to cells for energy and other biological functions.


When does most nutrient absorption occur?

Most absorption of nutrients occurs in the small intestine. And as far as digestion itself, it would be after the food particles are small enough to diffuse through the blood capillaries.


The small intestine is covered in millions of villi what are villi and what is their job?

Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.


In what organ of the digestive system do nutrients enter the blood?

Nutrients are absorbed into the blood primarily in the small intestine. This is facilitated by the small intestine's large surface area, thanks to the presence of villi and microvilli, which aid in nutrient absorption into the bloodstream.


What two digestive processes occur in the small intestine?

The two processes that occur are digestion and absorption. Digestion is the process by which your body breaks down food into small nutrient chemicals. While absorption is the process in which when the small nutrient molecules go through a wall of the digestive system and into the blood.


Where does most digestive food enter your blood?

Most digestive food enters the bloodstream through the small intestine. The small intestine is where the majority of nutrient absorption takes place, as the walls of the small intestine are lined with tiny finger-like projections called villi that help absorb nutrients from digested food.


How does the structure of the small intestine aid in the absorption of?

The small intestine is thrown into folds that increase its surface area by upto 600 times. This helps in the absorption by providing greater area for diffusion to take place through. Each villus (projection) also has a lacteal inside it, which helps in the absorption of lipids.


Advantage of having a long small intestine?

Having a long small intestine allows for more surface area for nutrient absorption. This means that the body can extract more nutrients from food, leading to better nourishment. Additionally, a longer small intestine can help in the digestion of complex carbohydrates and proteins.


9 What is the function of the rugae in the stomach and villi in the small intestine?

both rugae and villi are specialized "folds". the rugae allow your stomach to expand when you eat (like a balloon) and the villi increase the surface area in your small intestine for nutrient absorption


What Process in which food molecules pass from the small intestine to the blood?

Absorption is the process


How do microvilli help with absorption?

The microvilli have finger-like shapes originating from the villi that line the small intestine. They greatly increase the surface area of individual cells when it comes to absorbing nutrients.


Where in the digestive system does most of the absorption of nutrients into the blood stream occur?

small intestine
