Project 3.2.2: Digestive System Design Introduction During his or her lifetime‚ the average person eats his/her way through at least 20 tons of food. Meats‚ vegetables or sweets - whatever your diet‚ that’s 40‚000 pounds! Our digestive system works to turn this enormous amount of food into substances that the body can use for energy and for growth and repair. But what actually happens to these foods once they enter our bodies? How does the body process each tasty bite and harness the power locked

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are several important accessory organs that help your body to digest food but do not

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue‚ salivary glands‚ pancreas‚ liver‚ and gallbladder).[1] In this system‚ the process of digestion has many stages‚ the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components‚ until they can be absorbed and assimilated into the body. Chewing‚ in which food is mixed with saliva begins the process of digestion. This produces a bolus

The Physiological and Anatomical Similarities of the Human and Fetal Pig Body Abstract Through the dissection of the fetal pig‚ we were able to compare and contrast the structure and functions of the organs to those of a human. We dissected the pig and observed all the exterior and interior structures. We found that because both are mammals‚ the fetal pig’s structure was almost identical to the human body. Intro Since humans and pigs are both mammals‚ it can be very useful to study the

Digestive system 6.1.1 explain why digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down

nutrients which the body uses for energy‚ growth and cell repair. When I am chowing down my steak and potatoes‚ my digestive system is doing that exact thing. Our digestive system breaks down food into smaller molecules and into nutrients for the body. These nutrients include carbohydrates‚ protein‚ fat and vitamins. The digestive system is made up of the GI tract‚ also known as the digestive tract. The GI tract is a series of hallow organs going from the mouth to the anus. The organs that make up this
