The 2000-Meter Row: A Case in Homeostasis Adapted from the National Center for Case Study Teaching in Science* by Nathan Strong At the start 1. Recall that Jim’s heart and respiratory rate are increased‚ he was sweating and that his mouth was dry before the raise began. Explain what is happening to his autonomic nervous system (including which division is the most active) and specify exactly how those ANS responses are creating the symptoms noted. What changes do you think are occurring

Introduction to Histology Introduction Histology is the microscopic study of cells and tissues of organisms. This study is important in the overall understanding of anatomy and physiology of organisms. It helps to understand the structures and functions of various tissues that make up bodily organs and systems (Wendy Wright‚ 2014). The cell theory states that a cell is the fundamental biological unit. All living organisms are composed of one or more cells‚ and every bodily activity that takes

Histology analysis There were five steps involved in histological preparation. Step 1: Dissection and tissues collection The testis tissues were cut with a sharp scalpel into slices of not more than 2-3 mm thick and 10 mm long. The fixation process was commenced immediately after removal of the tissue sample. The specimen tube was filled with 20 ml of 10% formalin. The tissue was placed inside the specimen tube. Step 2: Dehydration Dehydration process begins when the fixed tissues was

HUMAN ANATOMY AND PHYSIOLOGY AN INTRODUCTION TO RESPIRATION In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some
