"Burp!" You cover your mouth with your hand‚ but it’s too late. The people at the next table in the lunchroom already heard. As you turn back to your soda‚ you think: Where did that burp come from? A burp — sometimes called a belch — is nothing but gas. When you eat or drink‚ you don’t just swallow food or liquid. You also swallow air at the same time. The air we breathe contains gases‚ like nitrogen (say: ny-truh-jen) and oxygen (say: ahk-sih-jen). Sometimes when you swallow these gases‚ they

Nutrition is a process; it is how the body puts all the processes together in order to provide what our bodies need to be healthy‚ to grow and to maintain good health while supplying all our nutritive needs. There are different stages to nutrition‚ it starts with the food we ingest‚ then it is digested‚ it can then be used and absorbed by the body and is then assimilated and finally any waste is eliminated. At the first stage of the process is ingestion and it could be argued that good nutrition

physically see and touch the anatomy of the mammalian body rather seeing it solely in text form. This gives us a better idea of how the structures are intertwined to form the body as a whole. On the first day of the lab I observed the pig’s digestive system which includes the liver‚small intestines‚ large intestine‚ and the pancreas. 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

Physiology & Anatomy Lab SC 145L Anatomy & Physiology I Lab Chemical and Physical Processes of Digestion Introduction: In this lab‚ we will see how different chemical processes occur as we observe how different enzymes digest different substrates and produce subunits. Key Terms: (found in bold in Lab Manual) Please define all bold terms in your own words: Enzymes- Large protein molecules made by your body cells. Catalyst- Without becoming part of the substance it will change the rate

to stomach. Gastric motility is also a key factor in stomach specific drug delivery. Brief knowledge of motility is necessary for developing a retentive form of drug. Gastric motility differs in fasting and fed states. In fasting states‚ an Inter-digestive myoelectric motor complex (IMMC)‚ a 2 hr. cycle of peristalsis is generated which progresses to ileocecal junction. It consists of 4 phases: a) Phase I: also called quiescent period with rare low amplitude contractions‚ lasting for 30-60 mins. b)

The start of the process - the mouth: The digestive process begins in the mouth. The ham sandwich is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules). On the way to the stomach: the oesophagus - After being chewed and swallowed‚ the food enters the oesophagus. The oesophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic‚ wave-like
