nutrients are absorbed in the digestive system
The cells that lines the GI Track into the bloodstream
The gastrointestinal tract, or GI tract.
Nutrients are absorbed throughout the digestive process. Specific nutrients are absorbed in the stomach and large intestines, but the majority of nutrients are absorbed in the… small intestines.
It eats the salt you eat
Most bacteria consume things already dead. They decompose stuff like shed skin, carcasses, and plant bits such as leaves. These do it by secreting digesting enzymes outside th…emselves onto the food source. The bacteria then absorb just what they need. http://www.everything2.com/index.pl?node... Other bacteria can photosynthesize. These include the cyanobacteria that produce oxygen for our atmosphere. They still contribute up 30% of the Earth available oxygen every year. Then there are the purple nonsulfur bacteria that do both, photosynthesize and get their energy from organic compounds. Some symbiotic bacteria help us digest the food we consume. These beneficial gut flora provide us with essential nutrients like vitamin B1 & B6 we cannot make ourselves. There are over 800 known species living in humans but people do not have all. Different populations of people have different collectives of gut bacteria. Understanding what a specific group of bacteria do in the gut and how they work together to digest may affect how we get energy from our food and gain weight.
The small intestines are responsible for the main absorption of nutrients for the body.
Most of the nutrients are absorbed in the small intestine and water, some vitamins and electrolytes (sodium, potassium ions) are absorbed in the large intestines.
In body,nutrients are absorbed in Small intestine by micro-villi present on the wall of it.
What are all over the outside of the small intestine to absorb nutrients and deliver them to cells of the body?
