Decreased blood pressure and the need to reabsorb sodium. PhysioEx allows students to repeat labs as often as they like, perform experiments without harming live animals, and conduct experiments that are difficult to perform in a wet lab environment because of time, cost, or safety concerns. Rebreathing You correctly answered: b. The stem cells are the building blocks they go through a various process called stem cells differentiation which allows them to be specialise. Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1.
There is a difference in pressures at the ends of the vessels. . How well did the results compare with your prediction? Decreasing the membrane size and solute concentration will reduce diffusion rates and can even prevent all diffusion. Thyrotropin-releasing The normal rat is You correctly answered: c. Stimulus frequency refers to You correctly answered: b. Negative What does it mean that the voltage just inside the membrane is negative? It is getting out any unneeded substances in the body or cleaning out the body quicker.
Rogers, Yvonne, Jenny Preece, and Helen…. The variable that affects osmotic pressure is You correctly answered: a. What information from this source seems the most important? We will write a custom sample essay on Physio Ex 9. Therefore, the K+ ions will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. The plasma, red and white blood cells, and platelets cause resistance as they travel through vessels.
It increased for the emphysema patient and decreased for the asthmatic patient. Submit this completed document by the assignment due date found in the Syllabus. Which of the following statements about metabolism is false? It increased for both patients. Gas pressure inside the lungs is lowered. This might result from a decrease in the radius of the efferent arteriole.
It does the same thing as the active force does except for in increases at the end again. If you close the one way valve, pressure will increase in the Bowman's capsule and filtration rate will decrease. A decreased afferent arteriole radius will increase the rate of glomerular filtration. Excrete Excess water and wastes 2. The nature of plasma membrane. Operating Strategy We shall place a lot of values on providing standard services to our customers by carrying out analysis….
There is less blood that is able to enter the glomerulus because of reduced radius of afferent arteriole, therefore the pressure and filtration rate are also reduced. Predict Question 3: What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the efferent arteriole? Exercise 4: Endocrine System Physiology: Activity 1: Metabolism and Thyroid Hormone Lab Report Pre-lab Quiz Results You scored 100% by answering 6 out of 6 questions correctly. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. Wave summation is achieved by You correctly answered: a. For this reason, an increase in urine volume would stabilize blood volume. Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Remember that you can clear the tracings on the screen at any time by clicking Clear Tracings.
My results went well compared to my prediction… Exercise 1: Cell Transport Mechanisms and Permeability: Activity 5: Simulating Active Transport Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. Excretion-filters water and solutes in the blood, the kidneys are able to excrete excess water Regulation- regulates plasma osmolarity which is the concentration of solution expressed as osmoles of solute per liter of solvent, plasma volume, body's acid-base balance, and body's electrolyte balance. How well did the results compare with your prediction? Ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack. It increased for the emphysema patient and decreased for the asthmatic patient. Procedure: In order to perform this lab I needed the following materials:….
Which of the following statements about metabolism is false? It shows more examples of fourth amendment…. During an asthma attack You correctly answered: b. What are two primary functions of the kidney? What are the components of the renal corpuscle? Our extensive online study community is made up of college and high school students, teachers, professors, parents and subject enthusiasts who contribute to our vast collection of study resources: textbook solutions, study guides, practice tests, practice problems, lecture notes, equation sheets and more. The increase of flow tube radius increased the flow rate, as predicted. If blood pressure goes down, the rate of glomerular filtration goes up.
Note that a decrease in force indicates muscle fatigue. Both increasing the afferent arteriole radius and decreasing the efferent arteriole resulted in an increase in glomerular filtration rate. Rename this document to include your first and last name prior to submitting, e. Submit this completed document by the assignment due date found in the Syllabus. How well did the results compare with your prediction? Hint: What variable was changed in the procedure? Increasing extracellular K+ causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. The infectious form of Chlamydia that is spread from person to person is the You correctly answered:… Exercise 5: Cardiovascular Dynamics: Activity 1: Studying the Effect of Blood Vessel Radius on Blood Flow Rate Lab Report Pre-lab Quiz Results You scored 100% by answering 5 out of 5 questions correctly. You may delete these instructions before submission.
Expiratory reserve volume is the amount of air that can be expelled after a normal tidal exhalation. Your answer: Proximal convoluted tubule — Loop of Henle — Distal convoluted tubule — collecting duct 4. What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the efferent arteriole? The amounts were higher than when it was at 70 beaker pressure. No, the level stayed steadily at 40mm. In experiment 2 the rate of facilitated diffusion relied on the amount of carrier proteins available to transport… 677 Words 3 Pages Exercise 2: Skeletal Muscle Physiology: Activity 4: Tetanus in Isolated Skeletal Muscle Lab Report Pre-lab Quiz Results You scored 100% by answering 3 out of 3 questions correctly.
