Mike McGraw: Hoiberg says Kris Dunn will practice today and theyâll decide tomorrow if he plays vs Toronto. If Dunn does play, wonât be a ton. #Bulls
Plasma or serum typically yields values 10 12% lower than observed in whole blood. After a meal, capillary blood may be 20 70 mg/dL higher than serum assuming average hematocrit of 41 45%. B. Monitoring systems are not as accurate as diagnostic systems and should not be used as such.
The flow of blood in the capillaries is controlled by structures called precapillary sphincters. These structures are located between arterioles and capillaries and contain muscle fibers that allow them to contract. When the sphincters are open, blood flows freely to the capillary beds of body tissue.When the sphincters are closed, blood is not allowed to flow through the capillary beds.apillaries measure in size from about 5-10 microns in diameter. Capillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue). Oxygen, carbon dioxide, nutrients and wastes are exchanged through the thin walls of the capillaries.
