digestive process in the mouth. Salivary amylase is created by by three large salivary glands. This amylase breaks down starch and carbohydrates. However‚ since only a few people keep the food in their mouth long enough for the amylase to digest the carbohydrates completely‚ it continues down to the stomach through the esophagus. A lot of people may think that the salivary amylase continues working on the carbohydrate. However since the stomach’s acidity is very high the salivary enzyme is inactivated. Carbohydrates

Aging is the accumulation of physiological and psychological changes over time. The Office of National Statistics showed that the aging population and increased prevalence of long-term conditions have a significant impact on health and social care and may require £5 billion additional expenditure by 2018 (ONS 2015). Common conditions of older age receive less investment and lower-quality care than general medical conditions prevalent in mid-life (Steel et al.‚ 2008)As budgets continue to tighten

accumulation of cells rather than an organ system. Protection‚ support and movement are the main functions of the Integumentary system‚ Skeletal system‚ and Muscular system. The Integumentary system is made up of skin‚ hair‚ nails‚ and the coetaneous glands. The functions of this system include protection‚ water retention‚ thermoregulation‚ vitamin sensation‚ and nonverbal communication. Then there is the Skeletal system made up of bones‚ cartilages‚ and ligaments. The functions of the skeletal system

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
