How does the digested food enter the circulatory system?

Answer 1

Products of carbohydrate digestion (simple sugars) and products of protein digestion (amino acids) move through brush border cells, diffuse through the interstitial fluids inside the villus, then enter a capillary. Products of fat digestion (triglycerides) also cross the brush border cell and interstitial fluid, but they enter lymph vessels, which eventually carry them to the blood.

Answer 2

the capillaries. Oxygen, nutrients & glucose diffuse through the capillaries because they're so small and thin then it goes into the fluid surrounds tissue cells which goes into your blood.

The transfer of digested food from the digestive system to the circulatory system takes place primarily in the small intestines.

Answer 3

It has three parts: the Duodenum, Jejunum, and Ileum.

After being processed in the stomach, food is passed to the small intestine via the pyloric sphincter. The majority of digestion and absorption occurs here after the milky chyme enters the duodenum. Here it is further mixed with three different liquids:

Bile, which emulsifies fats to allow absorption, neutralizes the chyme and is used to excrete waste products such as bilin and bile acids. Bile is produced by the liver and then stored in the gallbladder where it will be released to the small intestine via the bile duct. The bile in the gallbladder is much more concentrated.

Pancreatic juice made by the pancreas. It secrete enzymes such as pancreatic amylase, pancreatic lipase, and trypsinogen (inactive form of protease).

Intestinal juice secreted by the intestinal glands in the small intestine. It contains enzymes such as enteropeptidase, erepsin, trypsin, chymotrypsin, maltase, lactase and sucrase (all three of which process only sugars).

The pH level increases in the small intestine as all three fluids are alkaline. A more basic environment causes more helpful enzymes to activate and begin to help in the breakdown of molecules such as fat globules. Small, finger-like structures called villi, and their epithelial cells is covered with numerous microvilli improve the absorption of nutrients by increasing the surface area of the intestine and enhancing speed at which nutrients are absorbed. Blood containing the absorbed nutrients is carried away from the small intestine via the hepatic portal vein and goes to the liver for filtering, removal of toxins, and nutrient processing.

The small intestine and remainder of the digestive tract undergoes peristalsis to transport food from the stomach to the rectum and allow food to be mixed with the digestive juices and absorbed. The circular muscles and longitudinal muscles are antagonistic muscles, with one contracting as the other relaxes. When the circular muscles contract, the lumen becomes narrower and longer and the food is squeezed and pushed forward. When the longitudinal muscles contract, the circular muscles relax and the gut dilates to become wider and shorter to allow food to enter.

Answer 4

Digested food has been broken down into small enough particles that blood vessels attached to the digestive system can transport the food to where it's needed.
