They are too large and have to be broken down into amino acids.
Bloodstream
amino acids
Amino Acids are absorbed into circulation after the complete digestion of proteins.
The stomach
carboyhydrates
Fats are absorbed in the small intestine, along with carbohydrates and proteins.
In the large intestine,water and mineral salts are absorbed into the bloodstream.
They are broken down into simpler molecules by the digestive system so they can be absorbed into the bloodstream.
The cell membrane of the wall of the small intestine is a partially permeable membrane. Lactose is too big to pass through the membrane, and thus, cannot be absorbed into the bloodstream. I hope this answered your question. Laura Biology Teacher
Correct. The amino acid molecules are absorbed and allowed to pass to the bloodstream.
no
In the stomach; where the breakdown enzyme (pepsin) is at an optimum pH of 1-2 When broken down they form amino acids which are absorbed into the bloodstream by the ileum of the small intestine.
Fats that are unable to be transported by the bloodstream are absorbed by the lacteals. They are lymphatic vessels.

Small intestine
Oxygen and glucose.
