Day/Time____________ Cardiovascular Dynamics This experiment examines the factors that effect blood flow through a blood vessel. The rate of blood flow is influenced by the pressure gradient in the vessel‚ the radius of the vessel‚ the viscosity of the blood and the length of the vessel. You will be asked to systematically examine each of these factors to determine their effect on blood flow. Getting Started: Login to a CAL lab computer using ZULU Open the PhysioEx program From the

change during normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes‚ the pH level was always within the normal range for human body. 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No‚ the PCO2 level did not change during the course of normal breathing. Activity 2a: Hyperventilation – Run 1 1. At 20 seconds‚ pH = 7.45 2. At 40 seconds‚ pH = 7.53 3. At 60 seconds‚ pH = 7.65 4. Maximum pH = 7.66 5. Did the pH level of the blood

to Na+ and K+ in a resting neuron. Your answer: Membrane permeability to sodium is very low because there are only a few sodium leak channels. The membrane is more permeable to potassium because of the higher number of potassium leak channels. 5. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. Your answer: The resting membrane potential depends on the intracellular and extracellular concentrations of the Na+ and K+ ions. Conductance would change

ACTIVITY 5 Exploring Various Breathing Patterns You will establish the baseline respiratory values in the first part of this experiment. 1. If the grid in the data control unit is not empty‚ click Clear Table to discard all previous data. 2. Adjust the radius of the airways to 5.00 mm by clicking the appropriate button next to the Radius window. Now‚ read through steps 3–5 before attempting to execute them. 3. Click Start‚ and notice that it changes to Stop to allow you to stop the respiration. Watch

this report is to critically explain the physiological effects of exercise on the human respiratory system and cardiovascular system. To begin with‚ I will explain the two systems‚ their specific functions and how they inter-relate. I will then go on to analyse the effects of exercise on the two systems by looking at the way in which the body deals with an increased workload‚ and any health issues that may affect this. Cardiovascular system This system is responsible for pumping blood and oxygen

EXERCISE 6 1. A shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 25° downward from the horizontal. Find the work done by the shopper as she moves down a 50-m length of aisle. 1.6 kJ 2. A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. If the crate moves at constant speed‚ find (a) the work done by the 150-N force and (b) the coefficient of kinetic friction between the crate and surface. 900J

LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood
