what is the driving force for blood flow? - pressure gradient how does the body increase the blood vessel radius? - smooth muscle relaxation what is blood measured in? - ml/min what has the greatest effect on blood flow? - blood vessel radius the diameter of the blood vessel is the same as - two times the radius of the blood vessel the opening of the blood vessel where the blood flows is called the... - lumen what do you think will happen to the flow rate if the radius is increased by 0.5 ...

Describe the difference between the rate of diffusion seen for sodium and urea. - CORRECT ANSWERS a. urea diffused faster because it is larger than Na b. urea diffused faster because it is smaller than Na c. urea diffused slower because it is larger than Na d. urea diffused slower because it is smaller than Na. c. Glucose is a six-carbon sugar. Albumin is a protein with 607 amino acids. The average molecular weight of a single amino acid is 135 g/mole. There is no reason to run these s...

Physioex Quiz 1 Questions And Answers With Verified Solutions Filtration is a process that is passive Filtration is dependent upon a hydrostatic pressure gradient the filtrate all of these answers are correct an important place filtration takes place is the kidneys The reason none of the solutes were present in the filtrate was that the solutes were all too large to pass through. What does an increase in the driving pressure correspond to in the body? an increase in blood pressure. Aft...

What was the effect of adding Na+- K+ pumps to the simulated cell - Transport of the ions was faster The movement of sodium and potassium maintained by the Na+ - K+ pump requires ____________ and is ________ concentration gradient - ATP, against Sodium-potassium pump moves _______ sodium ions and ____________ potassium ions simultaneously - 3, 2 Lipid insoluble - Solutes that require active transport for movement might be too large to pass or might be At what concentration of ATP were th...

Neurophysiology of Nerve Impulses. Physioex 3 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. - correct answer Increasing the extracellular K+ reduces the steepness of the concentration gradient and so less K+ diffuses out of the neuron. 2. Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. - correct answer The membrane potential became less negative because l...
