Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

light on the relationship between carbohydrates and diabetes. Some of the information that I learned will be useful in my nursing career. Carbohydrates fill numerous roles in living things‚ such as the storage and transport of energy in the form of starch and glycogen etc. The basic carbohydrate units are called monosaccharides‚ such as glucose‚ galactose‚ and fructose. Diabetes Mellitus is a variable disorder of carbohydrate metabolism caused by a combination of hereditary and environmental factors

If I told you that you were‚ on a daily basis‚ consuming food that could potentially give you serious health issues‚ would you still eat it? The human body is in fact‚ designed to sustain a vegetarian diet. Most of you are‚ on a daily basis eating meat‚ poultry or fish – which have also been linked to a large number of chronic diseases and cancers. Alongside this‚ animals are treated extraordinarily cruelly and inhumanely when it comes to satisfying us humans. This is wrong and needs to be fixed

intestine—also called the colon—rectum‚ and anus” (NDDIC). Digestion begins in the mouth‚ where the food is cut and ground into small pieces. As the food is broken up‚ the first phase of chemical digestion occurs as saliva‚ which is secreted from the salivary glands. Amylase‚ contained in the saliva‚ begins the breakdown of starches into sugar. Once the food is softened by the saliva and swallowed into the esophagus‚ a muscular action‚ called peristalsis‚ helps to then push the food down the esophagus and into

Women with high estrogen levels‚ as a result of pregnancy‚ hormone replacement therapy‚ or the use of birth control pills‚ are at high risk for gallstone formation‚ diet very low calorie‚ prolonged fasting‚ and low-fiber‚ high-cholesterol‚ and high-starch diets all contribute to gallstone formation (Martin‚ 2014). Initially‚ some patients don’t present symptoms; however‚ as the disease progresses patient can experience pain that is localized to the epigastrium area or right upper quadrant‚ sometimes

People run differently in bare feet‚ some are more likely to land on their forefoot or midfoot compared with people running with shoes on‚ who tend to land on their rear-feet. Some reports say that barefoot running leads to reduced injury rates. When children are wearing shoes‚ they take longer steps than when they are barefoot. The Tarahumara participate in ultra-long distances across canyons while barefoot or wearing minimal sandals. Over the decades‚ there have been many reports of superhuman

The field of positive psychology is a relatively new area of study and its research is in its infancy. According to Alex Linley‚ Joseph‚ Harrington‚ and Wood (2006)‚ positive psychology in a nutshell‚ is the creation of a common language‚ which translates the study of positive traits and outcomes. It is also a domain of psychological strengths with a common metaphysical heritage‚ which relates and interacts with each other (Alex Linley‚ Joseph‚ Harrington‚ & Wood‚ 2006). One way to use positive psychology
