1. Scientists studied 616 capillary blood samples from jaundiced newborn infants. 2. A drop of capillary blood is obtained with an automated finger-prick, which is almost painless. 3. In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. 4. This structure serves to support capillary blood vessels, arranged so as to form a network of elongated meshes. 5. The fluid that is filtered from the capillary blood into Bowman s space is called filtrate or primary urine. 6. This means a good indicator of disease would be looking at trypanosome density in capillary blood and connective tissue. 7. The red blood cell travels through the arteries and into the tiny capillary blood vessels where oxygen is released. 8. In one study, the levels of progesterone in saliva and capillary blood were 10-and 100-fold greater than levels in venous blood, respectively. 9. Capillary blood sampling is generally performed by creating a small cut using a blood lancet, followed by test strip or small pipe.10. Patients were expected to self-test by placing a sample of capillary blood on a strip and inserting the strip into a reflectance meter.
