Glucose, amino acids and other soluble end-products of digestion are absorbed into the bloodstream throughout the small intestine by millions of tiny structures called villi. They have a low surface area, rich supply of blood and one-cell thick walls, which, combined, go a long way to increasing the amount of substances that can diffuse or be actively transported across the membrane into the blood.
the small intestine
amino acids glucose fatty acids n glycerol or absorbed in to the blood in the ileum
Different types of digested food particles travel from digestive to circulatory system. They are amino acids, glucose, fatty acids, glycerol, vitamins and minerals.
The proteins are broken down to amino acids and get absorbed. Carbohydrates are broken down to glucose (and fructose) and are absorbed. Fats are broken down to fatty acids and glycerol and absorbed. Minerals and vitamins are absorbed as such.
Small intestine
1. triglycerides 2. glucose 3. starch 4. amino acids
Triglycerides are absorbed by the lacteals of the small intestine. Triglycerides go into the lymphatic system and are converted into chyle.
All of the nutrients absorbed by the small intestine (including amino acids and glucose) travel through the hepatic portal vein to the liver.
Fat is absorbed by lacteals in the small intestine these have large surface areas to help with absorption and capillaries to absorb the fatty acids. Glucose and Amino acids is absorbed in the glomerulus in the kidney transported by the blood to the heart etc then it is reabsorbed in the bowman's capsule in the kidney.
After the glucose is absorbed into the blood it is taken to the liver and is either stored or distributed to cells throughout the body for energy. To provide enough energy for the body the liver regulates blood glucose levels. Example: excess glucose is converted to glycogen in the liver and is stored. Likewise, if blood sugar levels fall it is reconverted back to glucose. Not sure about amino acids :P
soluble end of products such as glucose , amino acids and fatty acids and glycerol
First, with the help of digestive system the food is broken down into smaller pieces which we eat and nutrients are separated which are further transported with the help of blood circulatory system.
