The capillary oncotic pressure is higher because of the plasma proteins trapped within the capillaries. The high oncotic pressure pulls the water from from the interstitium into the capillary.

Why there is oncotic pressure difference between atrtereoles and venules?
Oncotic pressure is the pressure exerted by colloid particles. As colloid particles do NOT leave the blood vessels oncotic pressure is SAME in arteriole and venules.
Blood plasma becomes tissue fluid by the process of?
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.
A plant with high is healthy and rigid?
A plant with high turgor pressure is healthy and rigid. When turgor pressure is high, it pushes the plasma membrane into the cell wall. This causes the plant to be turgid.
How does diffusion functions in the exchange of substances between blood and tissues?
Circulatory system is closed system exept at cappilory level. Here fluid leks out at proximal end of capillaries. It carries with it oxygen and digested food materials, disolved in plasma except plasma proteins. They are supplied to tissue cells and in return you get the carbon bi oxide and wasre products of metabolism. They reenters the circulation at distal end of capillary. At proximal end of cappilary, you have about 30 mm of mercury blood pressure and at distal end it is about 20 mm of mercury. Fluid is pulled back due to oncotic pressure of plasma proteins.
How does its high plus pressure condition aid its function of filtrate formation?
blood plasma is secreted from vessels in the glomular capsule. the higher the pressure of the blood when it enters the glomular capsule, the more plasma will be secreted. It's like having a water balloon with a few holes in it--if you squeeze the balloon (add more pressure), then water goes out faster. The plasma that is secreted into the glomular space is called filtrate. The more plasma secreted, the more filtrate that is produced.. The higher the pressure of plasma, the more plasma that is secreted.
What determines plasma oncotic pressure?
i haveNO idea:P
The presence of plasma proteins in the blood increases its?
oncotic pressure
What is the ability of plasma proteins to maintain plasma water volume called?
oncotic pressure
Where is albumin transported to?
In the blood plasma? it's a crucial component of it. Important as carriers and maintaining oncotic pressure.
What is the gradient called that is the driving force for the movement of water and dissolved solutes from the arterial ends of blood capillaries?
The blood pressure in the capillaries at arterial end is about 25 to 30 mm of Mercury. The oncotic pressure of the plasma proteins is about 22 mm of mercury. So there is net force, which drives out the fluid in the interstitial space. The fluid is sucked back at the venous end of the capillaries by the oncotic pressure of the plasma proteins. It should be called as pressure gradient.
Why there is oncotic pressure difference between atrtereoles and venules?
Oncotic pressure is the pressure exerted by colloid particles. As colloid particles do NOT leave the blood vessels oncotic pressure is SAME in arteriole and venules.
What is the difference between Osmotic and Oncotic pressure?
osmotic- pressure exerted by large molecule oncotic- presure exserted by proteins
What is Increased colloidal oncotic pressure?
colloidal oncotic pressure is also called colloidal osmotic pressure which is exerted by the proteins...proteins are also called colloids
What is normal blood oncotic pressure?

Why do we infuse iv albumin in a person?
To treat a variety of conditions, including shock due to blood loss in the body, burns, low protein levels due to surgery or liver failure, and as an additional medicine in bypass surgery. It may be used for certain conditions as determined by your doctor. Albumin (Human) is a concentrate of plasma proteins from human blood. It works by increasing plasma volume or serum albumin levels. Albumin is a major plasma protein produced in the liver. It increased the oncotic pressure of the blood and an increased oncotic pressure will draw fluid from the interstitial space into the blood vessel. During shock, a patients blood pressure decreases dangerously. By infusing albumin, we can increase the oncotic (colloid) pressure of the blood, draw more fluid from the interstitial space into the blood, and effectively increase blood pressure by increasing blood volume. Do not infuse albumin if: * you are allergic to any ingredient in Albumin (Human) * you have or have ever had heart failure, kidney failure or stable chronic anemia, or you are at risk for fluid overload

Which pressure is in excess and causes fluids to move from A to C?
Through oncotic pressure the body is able to hold water in the bloodstream. If this excess in pressure decreases, from conditions like liver disease, water will leak into surrounding organs and tissues preventing it from moving from point a to point c.
