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

V. Anatomy and Physiology The Urinary Tract The Urinary System rids the body of nitrogenous wastes while regulating water‚ electrolyte‚ and acid-base balance of the blood. Kidneys Kidneys are small‚ dark red organs with a kidney-bean shape lie against the dorsal body wall in a retroperineal position (beneath the parietal peritoneum) in the superior lumbar region. The kidneys extend from T12 to the L3 vertebra; thus they receive some protection from the lower part of the rib cage. Because

Year 10 Science: DNA Presentation Your presentation must include: Criteria - Diagram Explanation A - Clearly explains reasons why diagram was used‚ and clearly explains the structure of DNA An explanation of how you chose what sort of labelled diagram to include: The structure of the double helix allows for the DNA to be tightly packed into chromosomes. It also provides an extremely stable backbone with the negatively charged phosphates pointing to the outside of the molecule. This charge aids

Examine one interaction between cognition and physiology in terms of behaviour. Cognition is the mental action or process of acquiring knowledge and understanding through thought‚ experience‚ and the senses. Physiology refers to the way the organisms work in response. These interactions between a cognitive process and physiology create human behavior. one example of this interaction is the way mirror neurons work and how the body acts in response to these neurons. A mirror neuron is a neuron
