An increase in capillary pressure will shift fluid into or out of the capillaries
More fluid leaves the capillaries than returns.
By the process of ultra-filtration. At the proximal end of the capillary, you have pressure of about 30 mm of mercury. So the fluid leaves the capillary and enter the interstitial compartment. At the distal end of the capillary the pressure is about 15 mm of Mercury. The fluid in drawn in due to oncotic pressure at that end.
False, would increase the amount of fluid leaving the capillaries.
Increased blood hydrostatic pressure.
The net inward pressure in venular capillary ends is less than the net outward pressure in arteriolar ends of capillaries because of two main factors: the hydrostatic pressure and the osmotic pressure. In venular capillary ends, the hydrostatic pressure is reduced due to the resistance of the venous system, while the osmotic pressure remains constant. In arteriolar ends, the hydrostatic pressure is higher due to the force exerted by the heart and the osmotic pressure remains the same. As a result, more fluid is filtered out of the capillaries at the arteriolar ends than is reabsorbed at the venular ends.
Filtration results when nutrients are moved through the capillary walls by hydrostatic pressure. Hydrostatic pressure in the capillaries is greater than the osmotic pressure so there is a net movement of fluid and/or solutes out of the capillaries.
As blood enters the capillary bed on the arteriole end, the blood pressure in the capillary vessel is greater than the osmotic pressure of the blood in the vessel. The net result is that fluid moves from the vessel to the body tissue.At the middle of the capillary bed, blood pressure in the vessel equals the osmotic pressure of the blood in the vessel. The net result is that fluid passes equally between the capillary vessel and the body tissue. Gasses, nutrients, and wastes are also exchanged at this point.On the venue end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
water and waste will move in capillary . water and waste will move in capillary .
exchange of fluid that occurs across the capillary membrane between the blood and the interstitial fluid. This fluid movement is controlled by the capillary blood pressure, the interstitial fluid pressure and the colloid osmotic pressure of the plasma. Low blood pressure results in fluid moving from the interstitial space into the circulation helping to restore blood volume and blood pressure.
The hypothesis that fluid filtration through capillary membranes is dependent on the balance between the pressure the blood places on the membranes and the osmotic pressure of the membranes. The law relating to the passage of fluid out of a capillary depending on the hydrostatic and osmotic pressures of the blood and the same pressures of tissue fluid, the net effect of the opposing pressures determining the direction and rate of flow.
lymphatic capillaries are very permeable Lymphatic capillaries have valves that keep fluid from flowing backward. The blood capillaries are regulated by smooth muscle. Lymphatic capillaries are also a but larger than blood capillaries.
