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

Spirituality and the Physiology of Stress. Most Americans are suffering from moderate to high stress‚ with forty four percent reporting that their stress levels have increased over the past five years (Clay‚ 2011). Headaches‚ heart disease and high blood pressure have been associated with chronic stress. In the article Chronic stress may damage dna it states that Medical care professionals estimating that nearly seventy percent of doctor visits are directly related to ongoing stress (Sharf‚ n.d

The relationship between shape and diffusion rate Aim- To investigate the relationship between the shape of an object and the time taken for a substance to diffuse to its centre. Hypotheses- Part A) The 5x5x2.5mm block will turn clear first as the Surface area to volume ratio is high and the 10x10x10mm block will take the longest to completely diffuse the Acid to its centre. Part B) The flat‚ rectangular block will be the first to completely turn clear due to its high Surface Area/Volume Ratio

Homeostasis The ability of the body to maintain physiological parameters necessary for the preservation of life within a narrow range is referred to as homeostasis. In health‚ to a certain extent‚ the body can cope with this alteration and can constantly regulate the physiological changes in response to fluctuations in the external environment. For example‚ the maintenance of normal partial oxygen and carbon dioxide pressure‚ the right concentration of nutrients and waste products‚ the normal

Bodily responses to music Our body is a very sensitive being. When certain music is played it gets bodily reactions. Some music will make you laugh while some might make you cry. This chapters discusses how music effects the body and why. Music effects in two main ways; physiologically and physically. The first way we respond physiologically‚ which can be found in numerous ways. Physiological responses include internal bodily process.This would include heart rate‚ blood pressure‚ respiration

Homeostasis is the tendency of an organism or a cell to regulate its internal conditions‚ usually by a system of feedback controls‚ so as to stabilize health and functioning‚ regardless of the outside changing conditions. Humans use homeostasis to regulate control systems such as body temperature‚ osmotic balance‚ blood pressure‚ blood glucose and respiratory gases in tissues. This report will focus on thermoregulation‚ which is the ability of an organism to keep its body temperature within certain

Question The goal of this experiment was to find the answer to the question‚ ‘Are young children intrinsically motivated to see others be helped?’. The broad question gathered from this experiment is‚ ‘Do humans have an innate‚ genuine concern for the well-being of others?’. These questions are meaningful as this investigation could prove the existence of a distinctly human‚ nurture characteristic‚ that all share. Alternatives The experiment will likely have one of two outcomes‚ either young

The topic I have chosen to look at in this essay is to "discuss the principal ways in which heat is gained by and lost from the body‚ and explain the various mechanisms involved in regulation of body temperature. Briefly indicate how excessive cold and heat affect the body". The body gains and loses heat through the external environment by radiation‚ conduction‚ convection and evaporation of water. These are all physical mechanisms known to the human body. (Vander‚ Sherman & Luciano 1998). Radiation
