The line which represents the change in pressure if the arterioles are constricted along with its justification. Introduction: The blood is pumped from the heart to aorta which further circulates it to various small arterioles. These arterioles are responsible for carrying the blood to every part of the body. Arterioles experience variable resistance due to the presence of vascular smooth muscles. The contraction and relaxation of these muscles alter the diameter of arterioles.

Summary Introduction

To determine: The change in net filtration rate due to a change in pressure from line A to B along with its justification.

Introduction: The mass movement of fluid is known as bulk flow. If the movement of fluid is into the capillary, then it would be called absorption. On the contrary, if the movement of fluid is out of the capillary, then it would be called filtration.

Students have asked these similar questions

Let’s say an arteriole dilates to 50% greater than its original size (i.e., the new radius of the arteriole is 1.5 times the original radius). How does the blood flow rate through the arteriole change after dilation? (Hint: You do not need to know the exact values for viscosity, arteriole length, or pressure gradient in order to answer this question.)

Describe what Bulk flow across a capillar bed. A. In your description, define what Net filtration pressure is, hydrostatic pressure, and colloid osmotic pressure. B. What should occur at the arterial end of the capillary bed and what should occur at the venous end of the capillary bed? ( in other words, tell me if fluid should be moving out capillary or should be moving into capillary)

Blood velocity is slowest in the capillaries A. Explain the mechanics of why blood slows down in these blood vessels (objective N) B. What would happen if blood velocity was fastest in the capillaries?
