The Power of Vital. Undoubtedly‚ the most important component to human health and vitality of oxygen. In fact‚ human life would not be possible without it: oxygen produces ATP (adenosine triphosphate) and within ATP our bodies would immediately shut down. When a person breathes‚ there is an exchange of carbon dioxide and oxygen. The oxygen‚ which is taken in by the body from the atmosphere around us‚ is picked up by the hemoglobin in the blood and distributed to all of the body’s trillions of

Diarrhea Causes & Causes of Diarrhea Most of the time we know what caused our diarrhea‚ right? You had a meal and within 2 hours you were stuck on the toilet. Or you had some ice cream and an hour later the diarrhea hit you. Or maybe it was the next morning. But what is it about that meal or that ice cream that has you screaming‚ "I hate diarrhea!"? Or what about other times when diarrhea seems to come out of nowhere? What caused it then? I’m going to share with you a number of causes of diarrhea

chemical digestion that is in the mouth. Amylase is an enzyme that catalysts the breakdown of starch into sugars. Amylase is present in human saliva‚ where it begins the chemical process of digestion. Digestion prepares food for use by cells. It breaks down large complex food molecules and turns it into small‚ soluble food molecules. There are two types of digestion. Mechanical Digestion‚ which is the process of physically breaking down big chunks of food to smaller chunks‚ and Chemical Digestion‚ which

acid (HCL)‚ it is a term that covers all digestive enzymes. The process of digestion‚ absorption and assimilation begins with the enzymes present in the saliva that soften what we eat so it continues into the gullet as a paste. Penetrating the diaphragm‚ this gullet ends in a strong‚ muscular bag we know as the stomach. Having taken about 3 seconds to reach here‚ this foodstuff is turned acidic by the HCL for further digestion by peptin and gastrin before it enters the small intestines where this acid

purpose of the esophagus is to transport food from the mouth to the stomach. Digestion is the proper term for breakdown. The small intestine can hold about 48 quarts and is about 70 feet long. The three sections of the large intestine are the cecum‚ colon‚ and rectum. Bacteria is present in the cecum to break down roughages. Fecal balls are formed in the colon. The functions of the digestive system are digestion‚ absorption‚ and elimination. A non-ruminant herbivore is an animal that has a

Observation of Digestive and Circulatory System Introduction/Background: This week’s lab is about digestion and the circulatory system. Students will be learning about the different types of digestion and circulatory systems for different types of animals. Students will learn not only about the mechanical and chemical components of digestion‚ but also the complete and incomplete digestions. The lab will also teach the open and closed‚ single and double‚ circulation patterns. Several different models

organ of the alimentary canal The alimentary canal includes the mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine‚ large intestine‚ andanal canal Mouth Food enters the digestive tract through the mouth. The labia (lips) protect its anterior opening‚ the cheeks form its lateral walls‚ the hard palate forms its anterior roof‚ and the soft palate forms its posterior roof. The space between the lips and cheeks externally and the teeth and gums internally is the vestibule. The area contained by
