NEET PG DENTAL EXAM

Detailed explanation-1: -The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

Detailed explanation-2: -As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.

Detailed explanation-3: -After food leaves your small intestine, contractions push any food that remains in your digestive tract into your large intestine. Water, minerals, and any nutrients are then absorbed from your food. The leftover waste is formed into a bowel movement.

Detailed explanation-4: -When food enters the digestive system, enterogastrone hormones are released. These increase blood flow through the dilation of vessels supplying the digestive system. They also reduce blood flow in other parts of the body, leading to tiredness.
