The digestion process The digestion process begins in the mouth. First we take a bite of food. The presccence of food in the mouth stimulates the flow of saliva from the salivary glands. Saliva moistens the food and carries dissolved food molecules to the taste buds. Saliva helps digest food because it contains enzymes that start to break it down. After the food is covered with saliva‚ you then begin to chew your food. Chewing breaks down food into smaller pieces and also breaks apart fiber that

Digestion/ Absorption and Homeostasis In order to survive‚ our bodies must bring in energy and nutrients for the cells of the body through eating and digestion of food. To be carried to the cells of the body by the blood stream‚ food must be broken down to molecules. This breaking down of food into molecules‚ small enough to be absorbed into and carried through the blood stream‚ is carried out by the digestive system through the process of digestion and absorption. Digestion is the process of

fragments. This step is made possible by the contraction of the muscle of the stomach‚ the muscularis. Composed of three layers of fibers arranged longitudinally‚ circular and oblique‚ it mixes and kneads the food. Then begins the chemical digestion. Only the digestion of proteins begins in the stomach. The mucosa contains glands that secrete gastric juices. Under normal conditions‚ the production of juices is 2 to 3 L per day. Hydrochloric acid and enzymes are also produced by cells of the stomach

While the text states that taking "drugs won’t enhance creativity"‚ I disagree‚ because for one‚ some of our best music comes from the major drug using era known as the 60’s‚ 70’s‚ & 80’s.

DIGESTION IN THE MOUTH: Food is mechanically cut by incisors and canines‚ chewed by molars and premolars‚ and mixed with saliva by the tongue. The saliva has been produced by salivary glands‚ which pour it into the mouth through salivary ducts. This process of introducing food into the mouth is called ingestion. Chewing breaks food into smaller particles so that chemical digestion can occur faster. This cutting and mixing is called mastication. Moreover‚ food is chemically digested by salivary
