Question

Explain how digested food gets absorbed into the blood.. Plzz solve it

Answer 1

When the partly digested food enters the small intestine, the digestive enzymes present in the intestinal juices complete the process of digestion. This digested food is then absorbed by finger-like projections of the small intestine called villi. These villi are richly supplied with blood vessels or capillaries which absorb the digested food and transport it to all the organs via blood.


Hope this helps you.

Answer 2

The food get digested in small intestine then go to its second part known as jejunam....here viilli are present on its surface and Villi are connected to blood vessels.bsorption and egestionThese are the processes that happen in the digestive system:ingestion (eating) → digestion (breaking down) → absorption → egestionWe've already looked at how foods are broken down by enzymes in digestion. Now we will look at how the products of digestion are absorbed into the body.AbsorptionDigested food molecules are absorbed in the small intestine. This means that they pass through the wall of the small intestine and into our bloodstream. Once in the bloodstream, the digested food molecules are carried around the body to where they are needed.Only small, soluble substances can pass across the wall of the small intestine. Large insoluble substances cannot pass through.
