once-healthy neurons (nerve cells) in the brain stop working‚ lose connections with other brain cells‚ and die. While everyone loses some neurons as they age‚ people with dementia experience far greater loss. Researchers are still trying to understand the underlying disease processes involved in the disorders. Scientists have some theories about mechanisms that may lead to different forms of dementias‚ but more research is needed to better understand if and how these mechanisms

Cardio Pulmonary Practical The main aim of the practical was to assess‚ what affects did light exercise have on the systolic and diastolic blood pressure‚ heart and respiration rate‚ tidal volume‚ minute volume and percentage of gas. The readings were taken before exercise‚ during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls‚ during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the

Introduction In the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them) because they

1 Experiment Membrane Transport Objectives ► Referring to energy‚ what two ways can substances enter a cell? What is active transport? What is passive transport? How is osmosis related to diffusion? How can we demonstrate active transport? How can we demonstrate Brownian movement? How can we demonstrate diffusion (2 ways)? How can we demonstrate osmosis (3 ways)? In terms of relationships between substances‚ how can we define “hypertonic”‚ “isotonic”‚ and “hypotonic”? What is the relationship

airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation‚ it is one of two mandatory aspects of sound production; without these‚ there can be no speech sound. The organ generating the airstream is called the initiator; for this reason the production of airflow is called initiation. There are three initiators used in spoken human languages: the diaphragm together with the ribs and lungs (pulmonic mechanisms)‚ the glottis (glottalic mechanisms)‚ and the

Homeostatic Mechanisms Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state‚ while the world around it is changing constantly. There are many steps in the process of homeostasis. First‚ there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center‚ which decides the response. The information entering into
