Other functions take on: · financial aid in the digestion and metabolism of nourishment · vigour contraction ·Circulation and formation of blood cells · building new tissues-maintenance and localization ·Nerve transmission ·Maintain body temperature Physical digestion is when the provender molecules argon broken down into small pieces by the digestive systems organs to enable it to be processed by the body. chemic digestion occurs when special chemicals called enzymes break down the already small molecules til now smaller.

The hydrochloric acid provides acidic conditions requisite for the enzyme protease. This is also cognize as chemical digestion.

In the stomach some proteins ar broken down into smaller particles called polypeptides. From here the particles travel into the small intestine, which is the longest part of the digestive tract. Enzymes released from the pancreas and liver continue the s! ectionalisation of proteins, polypeptides and peptides and eventually amino group acids, which atomic number 18 absorbed through the enteral wall into the bloodstream. From there they ar delivered to organs and tissues for maintenance, repair and growth. If the amino acids ar not needed, they are broken down into urea and glucose. The urea...
