Small intestine
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.
In the small intestine most food is digested. The digestive system's organs work to make the food you eat soluble, so your body can absorb the energy (glucose). Once the churned up food is in the small intestine which is covered in villus (like a brush) the microvilli on the villus, to increase the surface area further, absorb all of the soluble glucose. Inside of the villus are capillaries that absorb most of the churned up food. But fatty acids called LIPID cannot be absorbed, so the lacteal running though the middle of the villus absorbs the fatty acids. :) hope that helped

All of the nutrients absorbed by the small intestine (including amino acids and glucose) travel through the hepatic portal vein to the liver.

You absorb nutrients in the small intestine. Your cecum absorbs water.
The function (job) of the intestine is to digest and absorb food. Digestion means breaking down food into soluble substances which can be absorbed. For example, starch is broken down into sugar (glucose) and protein is broken down into amino acids. So, the substances which are taken in by the blood from the intestine are digested foods, for example sugar (glucose) and amino acids. Most food is absorbed by the small intestine. Undigested food and water pass into the large intestine which takes some of the water back into the blood.
