Yes.
After food get digested, there are enzymes that break down larger molecules such as proteins and carbohydrates into smaller molecules before it can pass into the blood stream. Mainly in the small intestine, nutrients pass into the blood stream. Depending on the type of "nutrient" that get passed through, some just diffuse through by difference in concentration gradient. Some require active pumps in the lining of the small intestine to pump the "nutrient" into the cell or blood stream. Hope I didn't confuse you too much. In short, some molecule just pass through. Some needs to be pumped across the cell membrane.
After we had the food, first nutrient that is separated out is glucose and this process is carried out at the intestine.If not food is take for long time (when fasting), the blood glucose level will drops and thus insulin secretion is also low on no. Then the liver start releasing glucose into the blood stream by converting stored glucogen to glucose.
Yes, It does. When the food reaches the point that it is in the bloodstream, It goes through the large intestine.
through cells in the villi of the small intestine
The two main jobs of the small intestine are digestion and absorption. It digests food using enzymes and other substances, breaking down nutrients into smaller molecules. These nutrients are then absorbed through the walls of the small intestine and into the bloodstream to be used by the body.
some one help me
Protein is firstly broken in the stomach through Chloridric acid. In the small intestine, the protein is absorbed into the blood stream through the inner wall of the small intestine.
The Bronchus in the lungs provide a larger area for Oxygen and Carbon Dioxide to transfer into and out of the blood stream
Sugar enters the bloodstream through the small intestine after being broken down from carbohydrates consumed in the diet. The sugar molecule glucose is then absorbed into the bloodstream and used by the body for energy production.
Through millions of microscopic villosity placed on the walls of the small intestine.
The nutrients of food are absorbed at the intestine from where they reach the organs and tissues through the circulatory system.
Blood stream and then used 2 repair damaged or to replace dead cells.
