Digestion, Part 2 (Chemical) 1939?

The film explains the process of digestion, highlighting both muscular and chemical activities that occur in the digestive tract. It describes the journey of food from the mouth, where saliva begins breaking down starches, to the stomach, where gastric juices further digest proteins and carbohydrates. The film illustrates how food is mixed and moved through the stomach and into the small intestine, where enzymes from bile and pancreatic juice continue digestion. The absorption of nutrients into the bloodstream primarily occurs in the small intestine, facilitated by villi that increase surface area. The film concludes with the transportation of digested nutrients to the liver and ultimately to the body’s tissues.
