To review:
The overall net filtration pressure in capillary, and whether it is the net absorption or the net filtration that takes place in the capillary.
Introduction:
The colloid osmotic pressure gradient is created due to different concentrations of solutes in the blood and the capillary. The colloid osmotic pressure draws the water inside the capillary because less solute is present in the interstitial fluid and more solute is present in the blood. The hydrostatic pressure moves the water out of the capillary because the hydrostatic pressure inside the capillary is more as compared to the hydrostatic pressure inside the interstitial fluid.

- What is colloid osmotic pressure? In which direction does colloid osmotic pressure drive the movement of water in a capillary?arrow_forwardDescribe 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)arrow_forwardWhat force is responsible for moving fluids out of capillaries at the arteriole end and moving fluids back into the capillary at the venule end? What happens to fluids that do not re-enter the capillaries?arrow_forward
- Blood pressure at the arterial end of capillaries is about 40 mm Hg in humans. If blood pressure at the venous end is about 15 mm Hg, and colloid osmotic pressure is 25 mm Hg throughout, what is the net effect on fluid movement between capillaries and tissue spaces?arrow_forwardWhat is different about the capillary filtration occurring at Bowman’s capsule? What are othercapillary beds like?arrow_forwardWhich factor blood pressure or osmotic pressure has the greatest influence on the direction of fluid movement through capillary walls at (a) the venous and of the capillary and (b) the arterial end of the capillary?arrow_forward
- What determines the rate of blood flow through each exit tube?arrow_forwardHow does the hydrostatic pressure change from the arterial end of a capillary to the venous end of a capillary? Do you see similar changes in colloid osmotic pressure?arrow_forwardWhat is the only solute that has a significant concentration difference across the capillary wall? How does this difference influence water concentration?arrow_forward
