PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

BI309 Lab-2 Name of student: Anisa Dreunibakarua ID #: S11033198 Title: Effect of Temperature and Stimuli on Simple Muscle Twitch. Introduction: Skeletal muscle is a type of striated muscle that is attached to skeleton to facilitate movement by applying force to bones and joints through contraction. Skeletal muscle generally contract voluntarily when stimulated by the nerve‚ although they can also contract involuntarily at times. Muscle action is controlled by the Nervous System

Re-evaluation was completed during the fourth session‚ which indicated improvements in measures of muscle performance (e.g. MMT) of the hip and knee musculature. Similarly‚ mild improvements in bilateral hip and knee AROM were noted (Table 1). At the time of re-evaluation‚ three of the six STG were met and the remaining three were partially met (Table 4). No LTG were achieved at re-evaluation. There were no reports of falls since the initial visit. The patient reported that the KinesoTape® was continuing

HISTOLOGY PURPOSE: The purpose of this exercise is to be able to identify and correctly name the major tissue types in the body‚ as well as identifying the subcatergories of tissue types while observing them through the microscope and diagrams‚ and be able to explain the location and function of the tissue types in the body. There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used. EXERCISE 1: EPITHEILIAL TISSUE Epithelial Tissue Observations
