Physiology Exercise 3 Activity 1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: By increasing the extrecellular K+ the net diffiusion of K+ out the neuron through the eak channels is reduced. This is caused by the flow of ions following the concentration gradient of traveling from an area of high concentration to areas of low concentration. The higher concentration gradient would result in a reduced diffusions

The human respiratory system is one of the chief and most important which is very instrumental for survival. Prime function of the respiratory system is breathing. Inhaling oxygen and exhaling carbon dioxide is all that takes plays by function of the respiratory organs. Breathing is a process by which oxygen in the air is brought in to the lungs and further in to close contact with blood. The blood absorbs the oxygen and carries to all parts of the body. Simultaneously blood gives up waste matter

Respiratory system Asthma A chronic (long term) lung disease that inflames and narrows the airways‚ asthma causes recurring periods of wheezing ( a sound when you breathe)‚ chest tightness‚ shortness of breath‚ and coughing. The coughing often occurs at night or early in the morning. Asthma is characterized by inflammation of the bronchial tubes with increased production of sticky secretions inside the tubes. People with asthma experience symptoms when that airways tighten‚ inflame or fill with mucus

PhysioEx 9.0 Exercise 3 Neurophysiology of Nerve Impulses A C T I V I T Y 1 The Resting Membrane Potential 1. Explain why increasing extracellular K_ reduces the net diffusion of K_ out of the neuron through the K_ leak channels. Increasing the extracellular potassium reduces the concentration gradient‚ and less potassium diffuses out of the neuron and into the cell. 2. Explain why increasing extracellular K_ causes the membrane potential to change to a less negative value.

Activity 1 1. Describe two variables that affect the rate of diffusion. a. There are alot of different variables or factors that can affect the rate of diffusion‚ for example: size of the molecule‚ shape of the molecule‚ concentration gradient‚ charge of the ions‚ temperature‚ environment‚ etc. The rate of the diffusion can increase as diffusion distance increases‚ concentration gradient increases‚ surface area increases‚ temperature increases‚ and many more. 2. Why do you think the urea was not

Physio-EX Blood Analysis: Computer Simulation Introduction In this lab five blood tests will be performed: hematocrit determination‚ erythrocyte sedimentation rate‚ hemoglobin determination‚ blood typing‚ and total cholesterol determination. A “hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body‚ the higher the hematocrit‚ the more red blood cells are available to carry

Respiratory System WebQuest Introduction The primary function of the respiratory system is to supply the blood with oxygen. The respiratory system does this through breathing. Breathing is a natural process that we use to obtain oxygen‚ unlike eating or drinking to get energy. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The respiratory tract is responsible for taking the gases
