enzymes‚ hydrochloric acid‚ pepsinogen and mucin‚ are what begin the chemical breakdown of proteins. This churned food is called‚ chyme. At approximately 10 cc’s at a time‚ this liquefied chyme is released into the duodenum (the first part of the small intestine)‚ where the final 90% of absorption will take place. The duodenal area is probably the busiest part of the alimentary canal. If not‚ certainly one of the most crucial parts essential for life. In this main intersection‚ there are ducts secreting

Biology textbook- pg. 80 3) Distinguish between the autotrophic and heterotrophic nature of plants and animals. Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there

The liver was the largest organ in the fetal pig’s body and was shaped like small bean bag. I was actually surprised when seeing the small intestine because I didn’t know it was bigger than the large intestine‚ it was a series of long brown tubes. The pancreas of a fetal pig is along the bottom of the stomach. The pancreas is a

The amino acids are broken down further by the trypsin. Lipase breaks down fat. Amylase further breaks down fat. The gallbladder releases bile into the duodenum. This breaks down more fat. The liver stores the bile and filters toxins from the blood. After the duodenum‚ the next two sections of the small intestine are the jejunum and ileum. They
