How do osmosis and villi play a role in feeding cells the glucose they need?

Osmosis occurs in the small intestines which contain the villi. There are blood vessels connected to the villi so nutrients/glucose in the small intestines diffuses through the semi-permeable membrane of the cells in the blood vessel.

How do the finger like structures relate to the function of the small intestine?
If you mean the hairs on the cells they are villi and micro-villi
What are the Crypts of lieberkuhn?
They are intestinal cells found in the Small Intestine (SI). They are in the inter-villi space (between villi) and project down into the lamina propria of the SI. They contain Paneth cells, which secrete lysozymes.
Where or when is glucose absorbed into the blood stream?
Glucose is absorbed through the small intestine into the capillaries. There are millions of villi (finger-like projections) that line the inside of the small intestine to increase its surface area for absorption. Villi have a very rich blood supply, so the glucose can be absorbed quickly and the blood is taken away quickly, maintaining a steep concentration gradient for more glucose, and other food, to be absorbed.
Examples of active transport in animals?
Plants take in minerals like nitrates through their roots by active transport. The concentration of minerals in the root cells is normally higher than in the soil around them. Active transport uses energy from respiration to move minerals from the soil into the roots.
Maltase and sucrase is made in?
Maltase is an enzyme produced by the cells lining the small intestine.
What does 'villi' have to do with respiration?
Glucose is absorbed from the food in our small intestine. Inside the small intestine we have small finger like structures called villi. The glucose is absorbed by the villi. The glucose is absorbed (moves through) the villi and enter our blood system. Glucose is transported by our blood to all the cells in our bodies. Respiration takes place in our cells (in the mitochondria of cells). Respiration is where glucose (our bodies fuel) combines with oxygen (we breath in) to give us ENERGY, carbon dioxide and water.
Do cells in villi uptake glucose by active transport?
yes but sometimes no
What is the function of villi cells in the intestines?
the villi vastly increases the surface area for the absoption of food.
What cells belong in the digestive system?
Villi
How does the glucose get to the body cells?
Glucose is absorbed through the small intestine into the capillaries. There are millions of villi (finger-like projections) that line the inside of the small intestine to increase its surface area for absorption. Villi have a very rich blood supply, so the glucose can be absorbed quickly and the blood is taken away quickly, maintaining a steep concentration gradient for more glucose, and other food, to be absorbed.

Where in your body does your blood pick up glucose?
I would say the intestines, as they have to absorb large quantities of glucose and other carbohydrates by osmosis, when starches are digested by enzymes. It is able to do this because it has thousends of villi (finger like growths) on its surface that increase the surface area. The more surface area the more absorption takes place.
What is the purpose of villi in living cells?
villi are present to increase the surface area of cell for maximum absorbance of nutrients
Does the large intestine have villi?
The answer is small intestine.
What does the intestine wall made of?
Epithelial cells called villi
