Physiology

sentient life for that matter, anything more than complex arrangements of meat, neurons, and bone? The biophysical explanation of human physiology explains, quite in depth, the entire genetic makeup and biochemical arrangements from the simplicity of a ball and socket joint to the complexity of the brain. Surely the vast amount of research regarding human physiology could spearhead further research into the complexities of perception and thought, correct? There is no way to accurately describe…

Introduction: From rest to exercise the human body’s cardiovascular and respiratory systems must integrate and adapt to changing conditions—especially during incremental increases in submaximal exercise to maximal exercise. The coordination of cardiovascular and respiratory systems coalesce to form what is known as the cardiorespiratory system (Lotric & Stefanovska, 2000). Within muscle cells there are extremely limited stores for anaerobic energy; thus, a well-coordinated cardiovascular and…

2. Physiology Q=(P1 - P2)/ R Q= flow The amount of a liquid moving past a point in a given amount of time. P=Pressure (P1-P2) The amount of force placed on an artery at any given point in time. R= resistance Is the force that must be overcome for flow to occur. Describe the basic flow equation and resistance equation as they relate to vascular flow. b. Define Poiseuille’s Equation, and describe the effect on blood flow of a change in each variable. Poiseuille's equation states that the…

Surface Electromyography Amplitude During Sustained Isometric Contractions Connor Howe 31451131 HMKN 310 UBC Okanagan Greg duManoir October 18, 2015 Introduction Muscle fatigue is the result of a series of structural, metabolic and energetic changes in muscle fibers caused by changes in nervous system efficiency as well as decreased oxygen and nutrient supply (Cifrek, Medved, Tonković, & Ostojić, 2009). A major driving force behind muscle fatigue is lactate buildup. As lactate builds…

Aerobic Fitness Laboratory Report Ethan C. Bagwell University of Arkansas Introduction The problem addressed in this laboratory report is aerobic fitness and its association with cardiovascular disease and all cause mortality. Aerobic fitness is related to the ability to perform large muscle, dynamic, moderate to vigorous intensity exercise for prolonged periods of time (Thompson, Gordon, & Pescatello, 2014). Aerobic fitness has been considered a health-related part of physical fitness due to…

A measurement that measures the maximum volume that can be obtained by an individual is called VO2 max. VO2 physiology is two different categories 1) Utilization and 2) Delivery. Utilization is being able to extract and use oxygen. Delivery is about the transportation of oxygen cells either through the CVD or pulmonary system. VO2 is important for exercise and transporting oxygen to the muscles. VO2 max is important to health because it gives information on the function cardiac output of the…

cardiovascular responses in addition to increased stroke volume and heart rate. For example, exercise will result in a general, sympathetic vasoconstriction of arterioles with local overrides of endocrine vasodilation. Exercise also influences pulmonary physiology. The increased demand for oxygen intake and carbon dioxide expulsion results in an increase in pulmonary airflow and pulmonary ventilation, accomplished primarily through increases in breathing rate.E While pulmonary airflow and…

The use of measuring BLC in endurance athletes to evaluate exercise performance has been practiced for years (22-25). Some of the most common uses for BLC analysis include training adaptation analysis, identifying intensities in endurance exercise, predicting race outcomes, and prescribing endurance exercise with precise exercise intensities (2). The majority of the prescriptive work for exercise leans toward the estimated amount of contribution of the aerobic system during exercise based off of…

Sickle Cell Anemia Anatomy and Physiology 9/1/2014 Victoria Nimtz Definitions and History: Sickle Cell Anemia is a genetically passed disease. Instead of having normal disc – like red blood cells, a person would end up producing semicircular (sickle) shaped blood cells. This turns into a huge problem because the semicircular shaped blood cells block the blood flow within the blood vessels, which happen to carry inside them a protein known as hemoglobin, which ends up carrying oxygen from…
