Blood pressure is lower at the arterial end than the venous

Blood pressure is lower at the arterial end than the venous end of the capillary bed Reabsorption occurs at the arterial end and filtration occurs at the venous end High blood pressure and filtration both occur at the venous end of the capillary bed High blood pressure and filtration both occur at the arterial end of the capillary bed Which of the following would occur if the pre-capillary sphincters in the were to all undergo vasoconstriction at the same time? Blood pressure would dramatically increase Heart rate and respiration would increase Blood pressure would dramatically decrease Blood volume would increase Approximately what percent of interstitial fluid is not reabsorbed at the venous end of the capillary bed? 5-10% 10-15% 20-25% 30-35%

Solution

Please find the answers below:

Answer 10: Choice D (when arteries divide into arterioles, the diameter of the vessel reduces. This causes increase in rate of flow of liquid inside the vessel and hence, blood flow rate increases. Further, the arteriole bed is the site for filtration of blood at the vascular bed.)

Answer 11: Choice C (Since the arterioral and venule ends are closed at the ends, there will be formation of a liquid pressure head at this particular location of the vessel. This pressure head will prevent flow of blood from the pre-arteriole end and further, reduction of blood pressure will take place at the post-venule end. This will cause a local decrease in blood pressure until this pressure head is normalized)

Answer 12: Choice C (The interstitial fluid contributes to nearly 20-25% of the total fluid content of the body. Since this fluid remains in constant exchange of materials with the matrix, it can be deciphered that nearly 20-25% of the interstitial fluid remains un-absorbed at a given time)
