The body is made up of a number of systems that all interlink and produce everything we need in order to survive. Within the body there is the digestive system; the circulatory system‚ the nervous system‚ the muscular system‚ the skeletal system and the reproductive system. These systems are all part of one another and they share organs‚ tissues and cells and that is how they interlink. The diagram above shows each system and where they are located in the body. Each system is shown in a different

Structures and functions of the Digestion System This essay aims to explain the structure and functions of the digestion system‚ starting from consuming a cooked dinner to chemical and physical changes within the body‚ to prepare or help absorption of vital nutrients and help disposal of waste. The structure of the digestive system starts with the gastrointestinal tract‚ it is a tube that runs from the mouth to the anus and because of this some scientist says it is an external organ; there

ruminant animal. The digestive system includes the mouth‚ esophagus‚ four stomach parts‚ a cecum‚ a small intestine and a large intestine. Goats have no upper teeth so they use the dental pad‚ lower teeth‚ tongue and lips to eat their food. The four compartments to the stomach are the rumen‚ the reticulum‚ the omasum‚ and the abomasums. The esophagus is what moves food from the mouth to the stomach. It opens into the stomach at the opening of the rumen and reticulum‚ which helps transfer both gases

and tube 5 was a maltose control (also with water) that showed no starch. If control tubes 3‚ 4‚ or 5 were not done‚ then what is perceived as digestion might really be starch or maltose contamination. Saliva would not be active in the stomach because the stomach pH is too low. Boiling inactivates‚ or denatures‚ enzymes. 10. Tubes 2‚ 6‚ and 7 showed the effect of pH on amylase activity. The results of this experiment indicate that the activity maximum of amylase is at pH 7.0‚ whereas pH 2.0 and

broken up pieces of food mix with saliva and break down into a substance called bolus‚ which is a ball of chewed food. Bolus then passes through the pharynx‚ which helps us swallow‚ into the esophagus and into the stomach. The stomach further breaks down the bolus with highly acidic stomach secretion and is turned into a semi liquid mass called chyme. This process could take 2 to 6 hours depending on the amount of food and type of food. The chyme then moves to the small intestine. The small intestine

found in the stomach. It was identified in 1982 by Barry Marshall and Robin Warren‚ who found that it was present in patients with chronic gastritis and gastric ulcers‚ conditions that were not previously believed to have a microbial cause. It is also linked to the development of duodenal ulcers and stomach cancer. However‚ over 80 percent of individuals infected with the bacterium are asymptomatic and it has been postulated that it may play an important role in the natural stomach ecology. More
