INTRODUCTION TO PHYSIOLOGY AND HOMEOSTATIS PHYSIOLOGY 1.1 Intro to Physiology Physiology: the study of the functions of living things‚ how the human body works Two approaches explain the events that occur in body -purpose of the body process - mechanism in which the process occurs Physiologists view the body as a machine whose mechanisms of action can explained in terms of cause and effect sequences of physical and chemical processes. Physiology is closely related to anatomy: the

Physiology Assignment Name Class Date Every organism has specific characteristics that make it ideal for living in the certain environment that it resides. For example‚ owls are birds that have adapted to hunting at night. They have many adaptations that allow them to be successful night hunters. One adaptation that the owl has involves their eyesight. The eyes of owls are sunk in. This allows an owl to collect and intensify light making it better able

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

Population Genetics of the Alu Insertion on the PV92 region of Chromosome 16 Abstract: PCR is a laboratory method used to amplify a small‚ specifically targeted‚ amount of DNA. It has three steps‚ the denaturing of the template DNA‚ the annealing of the primers to the DNA templates and the extension of the new DNA by Taq DNA polymerase. The Alu insert on the PV92 region of chromosome 16 is targeted and its frequency is measured according to the Hardy-Weinberg equilibrium in the Vanier HTK population

Life story on the man behind genetics Johann Gregor Mendel was a biologist and ordained priest who conducted experiments in heredity. He used his resources at his monastery to grow thousands of pea plants‚ keeping detailed records and calculations that debunked the previous theory of “trait blending.” Although people largely didn’t recognize his work during his lifetime‚ his lengthy research showed that characteristics can be dominant or recessive and are passed on independently. These facts transformed
