I think the answer you are looking for is the glomerulus.
Blood flows in capillaries, but there is blood leaks out from the capillaries, known as tissue fluid or interstitial fluid.
Generally the blood pressure at arterial end of the capillaries is about 30 mm of mercury. The blood pressure at the venous end of the capillaries is about 15 mm of mercury. The fluid exit the capillaries at arterial end. Fluid enters the capillaries at venous end.
blood
False, would increase the amount of fluid leaving the capillaries.
Tissue Fluid
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.
the lymhpatic system
Blood
Fluid enters the lymphatic system (this system returns fluid and proteins to blood) by diffusing into lymph capillaries. This fluid is now called lymph and is kind of like interstitial fluid in composition. This movement of fluid is determined by net balance. It only diffuses into the capillaries if there isn't enough fluid there to begin with.
Urinary
Tissue fluid or interstitial fluid, though blood leaks out as well x
Capillaries allow Glucose and oxygen to move out of the blood in the capillaries into interstitial fluid and into the cells. Fluid is exchanged between capillary blood and interstitial fluid.
