The phenomenon of homeostasis is understood as the ability the body has to stabilise its internal environment despite the ever changing external conditions (Waterhouse‚ 2007). This internal environment is an atmosphere which surrounds the cells and is therefore the medium in which the cells are in direct contact with in the body (Sherwood‚ 2001). The internal environment is essential for cell survival because cells require a constant supply of oxygen and food which is exchanged from the external

Clinical Depression - is the most frequently encountered mental illness. Clinical depression is now considered a physical condition in which there is a fault in the brain chemistry. It may afflict up to 5% or more of the population. Symptoms of depression include a distinct change in mood accompanied with an extreme feeling of hopelessness. Other symptoms

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

Introduction A computerized simulation experiment will be conducted in order to study the cell transport mechanism via the cell’s selectively permeable membrane and passive processes of simple and facilitated diffusion. The plasma membrane is a gateway which allows nutrients to enter the cell and keep undesirable substances out‚ hence‚ making it selectively permeable. One method of transport is called active transport‚ which uses ATP to transport substances through the membrane. The other is

Introduction: Homeostasis is the tendency of the body to seek and maintain equilibrium‚ a state of balance‚ within its internal environment. Endotherms are “warm blooded” animals that produce and maintain their own internal body heat. Most mammals and a few birds‚ are endotherms; this is beneficial because the enzymes in the body that carry out metabolic processes have an optimum temperature at which they function‚ having the body constantly be‚ or be close to‚ this optimum internal temperature

Purpose The purpose of this experiment was to become familiar with the electrocardiograph to help us determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread
