BTEC BIOLOGY ASSIGNMENT 3 TASK 1 HOMEOSTASIS Homeostasis can be defined as a point of balance or internal equilibrium that all kind of system both living and non-living can work to keep themselves in this state of balance. Mechanisms of homeostasis in human body Temperature Regulation: If your body too hot or cold‚ there are several ways in which your temperature can be controlled. They involve sweating‚ shivering‚ capillaries and hairs. As we learn in the class when your body becomes; Too

PET 3351 Exercise Physiology Second Exam Review (Fall 2012) Chapter IV: The Physiological Basis of Muscular Strength and Flexibility 1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition‚ strength should be assessed using one repetition maximum (1 RM)‚ though we often estimate strength using tests that may involve multiple repetitions. 2. In strength training and rehabilitation‚ emphasis should be given to both the concentric

Mechanism and Physiology of Regeneration in Urodeles 2013 Mechanism and Physiology of Regeneration in Urodeles Urodeles or more commonly known as salamanders are any of approximately 550 extant species of amphibians under the Order Caudata.1 Urodeles’ distinctive factor that makes them different from other amphibians like frogs and caecilians is the retention of a full tail. Frogs actually lose their tail after leaving the larval stage and on the other hand‚ caecilians lack or have a small

ANATOMY AND PHYSIOLOGY OF THE HEART Anatomy: The heart and heart wall layers: The heart is located in the left side of the mediastinum; it consists of three muscle layers the Endocardium‚ myocardium‚ and epicardium. The epicardium is the outermost layer of the heart. The myocardium is the idle layer of and actual contracting muscle of the heart. The endocardium is the innermost layer and lines the inner chambers and heart valves. Pericardial sac: The pericardial sac encases and protects

Aerobic Training vs. Anaerobic Training Each person has different goals when wanting to become physically fit‚ but not many people know the difference between aerobic and anaerobic training. Even though aerobic and anaerobic training both contribute in maintaining overall health and both produce energy through glycolysis‚ which is the conversion of glucose into pyruvate‚ the training are different to achieve different results and the metabolic processes used by these two types of training

Transpiration Abstract This lab demonstrates how different environments effect the rate of transpiration in plants. A potometer is set up and placed in four different environments: one simply at room temperature (the control)‚ one with a fan pointing toward it creating a gentle breeze‚ on with a floodlight on it and a beaker felled with water as a heat sink‚ and one where the leaves are misted then covered with a transparent plastic bag. It is imperative that the tubing doesn ’t have any bubbles

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates
