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

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

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

Introduction “Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal equilibrium when dealing with external changes” (2). “Homeostasis keeps the body’s environment under control and keeps the conditions right for cells to live and function. Without the right body conditions‚ certain processes (e.g. osmosis) and proteins (e.g. enzymes) will not function properly” (1). Thermoregulation is the process that allows the cyclists
