ANATOMY

Detailed explanation-1: -When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.

Detailed explanation-2: -Carbohydrate digestion begins in the mouth where salivary amylase starts the breakdown. After breaking down throughout the digestive system, monosaccharides are absorbed into the bloodstream. As carbohydrates are consumed, the blood sugar levels increase, stimulating the pancreas to secrete insulin.

Detailed explanation-3: -The circulatory system is responsible for the flow of blood throughout the body, and in doing so, ensuring each part of the body obtains the necessities for activity, whereas the digestive system is responsible for the ingestion, break down, absorption, and excretion of nutrients and minerals.

Detailed explanation-4: -Absorption: Going to the Blood Stream The first organ to receive glucose, fructose, and galactose is the liver. The liver takes them up and converts galactose to glucose, breaks fructose into even smaller carbon-containing units, and either stores glucose as glycogen or exports it back to the blood.
