Homework Answers
- Mechanical digestion refers to the breakdown of food particle by mechanical force that is teeth and in chemical digestion the ingested food is broken down into smaller particles by releasing chemical substances such as acid and base.
- Mechanical digestion occurs from mouth to stomach where chemical digestion occurs from mouth to intestine
- In mechanical digestion, major part occurs in the mouth and major part of chemical digestion occurs in stomach.
- In mechanical digestion, large molecules are broken down into smaller molecules while in chemical digestion higher molecular weight compounds are broken down into lower molecular weight compounds.
In chemical digestion, small intestine is the organ where most of the digestion and absorption take place

Only animals with a complete digestive system have evolved specialized organs for digestion. Why? incomplete digestive system (2-way) - This system has a sac-like gastrovascular cavity (GVC) with only one opening to the environment. In this system, food passes through the mouth into the GVC where extracellular and intracellular chemical digestion takes place. The GVC extends throughout the body of the animal so that as food is absorbed it is available to the tissues; no transport system is needed. Waste...

Select the statement below that is NOT true of the enterohepatic circulation? A) Reabsorbing bile salts in the ileum gives more time to emulsify lipid and aid in their absorption within a greater length of the small intestine. B) The reabsorption of bile salts allows them to be reused within new bile....
