9. digestion is the process of physical and chemical breakdown of food to allow useful nutrients to pass through the intestinal membranes into a. blood circulation. b. the liver. c. alveoli. d. the spleen

B. the liver.

Explanation: Digestion is the process of physically and chemically breaking chunks and large molecules of food into small molecules that will pass through cell membranes. Digestive enzymes are substances that break down complex nutrients:

* Proteins into simpler amino acids

* Sugars into simple sugars, such as glucose

* Fats into fatty acids and triglycerides

Absorption is the process of transferring digested food from intestinal membranes into the blood circulation, which takes most nutrients straight to the liver for further processing and/or storage.
