B1: The permeability of the cell increases enormously during the action potential. Comte Whitney Electricity is vital for neural function and communication. The semi-permeable membrane and presence of charged particles in solution (ions)‚ enables the cell to have control of an electric potential. The cell The concentrations of Na+ and K+ ions upon either side of a cell’s membrane are not equal. In order for the equilibrium to be restored‚ sodium will attempt to enter the cell‚ whilst potassium will

Action Research 1.Foreign language teachers develop insights into their students’ learning from observing their behavior. 2.Reflective teachers analyze the students’ behaviors‚ identify potential problems‚ modify their teaching practices‚ and evaluate the results. 3. Some ideas succeed; others fail—sometimes surprisingly. 4.This process is called action research. 5. Action research is classroom-based research conducted by teachers in order to reflect upon and evolve their teaching. 6.It is a systematic

Introduction Cardiac contusion is an injury‚ or bruise‚ to the heart. This means that the chambers of the heart (atria and ventricles) are injured by a strong blow (trauma) to the chest area. Mild injuries to the heart may cause no symptoms. More serious trauma to the heart may cause pain and an irregular heartbeat. In rare cases‚ it can lead to shock and death. Depending on the trauma or accident‚ other body parts‚ such as the lungs and ribs‚ may also be injured. Prompt treatment is important to

Steven Ofstedahl BI 243 Short report Cardiac Arrest The circulatory system along with the heart make are what make up the cardiovascular system. The heart works as a pump that pushes blood to tissues‚ organs and cells in your body. The blood can be pumped throughout the body through a series of arteries‚ veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body‚ while veins help bring that blood back to the heart. Arteries carries oxygenated blood away

major veins they are the pulmonary veins. The pulmonary veins are large blood vessels that receive oxygenated blood from the lungs. A Cardiac surgeon is a person that works on the heart when there is a problem and cause. The heart is the most beautiful organ in the body there is. The heart is what keep the body alive and flows the blood. The development of cardiac surgery and cardiopulmonary bypass has lowered the rates of being performed. Performing on the heart comes with many complications when

for the situation around them. There are three different types of syncope‚ including cardiac‚ non-cardiac‚ and neurocardiac. There is three stages of syncope‚ which are‚ pre-syncope‚ syncope‚ and recovery. There are many signs and symptoms for each stage of syncope. No matter the type of syncopal episode there is one way to go about treating the patient. Cardiac syncope occurs when there is an “inadequate cardiac output and usually occurs as a result of a serious underlying heart condition (Grimes)”

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters
