This dynamic displacement of materials between the interstitial fluid and the blood is named capillary exchange.pproximately, seven percent of the body's blood is in the capillaries which continuously exchange substances with the liquid outside these blood vessels, called interstitial fluid.

The Base Diet for Birds: Food That Is Balanced. In the wild, birds eat a vast variety of foods: seeds, nuts, grasses, flowers, fruits, insects, the list goes on. The change in seasons brings new types of foods, and birds nourish themselves on whatâs available.
Depending on their age and species, baby birds may eat every 10-20 minutes for 12-14 hours per day, consuming a diet rich in insects for sufficient protein to ensure healthy growth. No human other than a licensed bird rehabber has the proper equipment, food supplements or endurance to keep up that frantic feeding schedule.
