The FEV1% decreased proportionally as the radius decreased. Review Sheet Results 7-2 5. What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema was selected? Why did these values change as they did? 6. Which of these two parameters changed more for the patient with emphysema‚ the FVC

the acid in lactate acid‚ it interfere with electrical signals in muscles and nerves‚ slows energy reactions‚ and impairs muscle contraction. The burn up we feel in intense exercise is the cause of hydrogen ion. During this experiment(Muscle fatigue lab) it will be seen that after a while of squeezing a small ball there won’t be the same amount of energy that was started with first and you will feel a burn in your arms which makes you feel hurt and don’t do a lot of squeezing; which is called the

resting neuron. _____________________________________________________________________ Potassium is more permeable than sodium in a resting neuron. Membrane permeability to sodium is very low because there are only a few sodium leakage channels. 5. Discuss how a change in Na_ or K_ conductance would affect the resting membrane potential. ________________________________________________ A change in permeability would affect the intercellular and extracellular concentration of ions during resting
Premium Action potential
membrane to Na+ and K+ in a resting neuron is different because of the varying number of leak channels. A cell has more potassium leak channels and has a higher permeability compared to the fewer sodium channels resulting in a lower relative permeability. 5. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. Your answer: The cells resting membrane potential is

The action potential increased with the heated rod. 5. Describe the types of stimuli that generated an action potential. The glass rod and glass heated rod‚ the 3.0V and higher voltage‚ the sodium chloride‚ and the hydrochloric acid. 6. If you were to spend a lot of time studying nerve physiology

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
