Food Processing in Human Body System. Foods are very important to human body. According to Vittadini et al. (2001)‚ foods provide energy that isneeded for human in order to do daily activities. Besides that‚ food is important for growth and it supplies vitamins and minerals to repair any damage in human skin and also prevent the body to get illnesses easily (Vittadini et al.‚ 2001).

occur‚ and the brain has a difficult time functioning properly. On the other hand‚ excessive amounts of glucose within the bloodstream can cause nerve damage‚ blindness‚ cardiovascular issues in the lower extremities‚ and kidney malfunctions. The pancreas is the main organ in the body that helps to regulate blood glucose levels within the body‚ releasing insulin when levels are high and glucagon when levels are low. In this experiment‚ we were interested to see how exercise impacted the body’s

Invertebrate Endocrinology Overview of the Endocrine System * System of ductless glands that secrete hormones * Hormones are “messenger molecules” * Circulate in the blood * Act on distant target cells * Target cells respond to the hormones for which they have receptors * The effects are dependent on the programmed response of the target cells * Hormones are just molecular triggers * Basic categories of hormones * Amino acid based: modified amino acids (or amines)

The purpose of this paper is to briefly discuss a tiny thing in your brain called the pituitary gland‚ talk about a few symptoms one may have if their pituitary gland is not functioning as it should‚ and what type of tests are done to help solve these issues. So have you ever just felt off‚ not like yourself‚ sluggish or irritable? Well good news it is probably just the pituitary gland that is acting up like a wayward teenager. While I may make light of this‚ it could be something extremely serious

Physiology of stomach:- For understanding approaches for gastro retention‚ it is essential to overview gastric physiology and gastric motility. The stomach is situated in the left upper part of the abdominal cavity immediately under the diaphragm. Human stomach has a resting volume of 25-50ml‚ which can distend upto1500ml following a meal. It is divided into 5 anatomical parts: a) Cardia:- First part of the stomach below the esophagus. It contains cardiac spincter‚which is a thin ring of muscle

DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

I have always been interested in the human body. So why not learn more about it? When I get older I want to be an orthodontist. Learning about digestive system helps me learn more about how the body works. Before I started this research I didn’t really know that much about the digestive system. I mostly knew the basics‚ like that food moves from the mouth to the throat to the stomach and then leaves the body. But in reality there is much more to digestion that I didn’t know about. I found plenty
