Now this may sound weird but according to livescience.com “Cells along the inner wall of the stomach secrete roughly 2 liters (0.5 gallons) of hydrochloric acid each day‚ which helps kill bacteria and aids in digestion. If hydrochloric acid sounds familiar to you‚ it may be because the powerful chemical is commonly used to remove rust and scale from steel sheets and coils‚ and is also found in some cleaning supplies‚ including toilet-bowl cleaners.

I. Fetal Pig Dissection II. Purpose Sus scrofa‚ or the domestic pig is a member of the class Mammalia and the order Artiodactyla. Since we as humans are also a member of class Mammalia‚ we have a good deal in common biologically with pigs‚ although we might not like to think so. Since we have a good deal in common‚ it is very helpful for us to study these animals both anatomically and physiologically. We do this when we test medicines on pigs‚ perfect surgical procedures on pigs‚ and even when

three major functions of the digestive system the secretion‚ digestion‚ and absorption. Accessory organs such as salivary glands‚ liver‚ gallbladder and pancreas have duct that lead into the digestive tract and thus support digestive function. Digestion is defined as the mechanical and chemical breaking down of food into smaller components‚ to a form that can be absorbed and utilized by the cells of the body. The two phase of digestion are mechanical and chemical or enzymatic. The former involves
