Questions to Accompany Physio-Ex: Cardiovascular Dynamics 1. Describe the relationship between blood pressure and blood flow. Blood flow is the amount of blood flowing through a vessel‚ tissue‚ or organ during a given period of time and Blood pressure is the force exerted on a vessel wall by the blood traveling through it. 2. Describe the relationship between blood viscosity and blood flow. As blood viscosity increases‚ blood flow decreases. 3. Describe the relationship between vessel

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

Physio Cardio Lab Report Answers Activity 1 Questions: 1. Explain how the body establishes a pressure gradient for fluid flow. Pressure gradient is the flow rate of a liquid through a pipe. This is directly proportional to the difference between the pressures at the two ends of the pipe and inversely proportional to the pip’s resistance. The pressure gradient is directly dependent upon blood vessel radius which essentially controls blood flow. The bigger the blood vessel radius‚ the more

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
