21.   This is seen as a greyish-white accumulation of material which grows and obstructs blood flow.

22.   Massage may help to increase blood flow to specific areas of the body.

23.   It works only in the veins, where the blood flow is slower.

24.   On the ground the top and bottom parts of the lung have different patterns of air flow and blood flow.

25.   Even in the absence of gravity, different parts of the lung have different levels of air flow and blood flow.

26.   Platelet activating factor also caused a marked decrease in the pancreatic blood flow comparable with that observed after caerulein infusion.

27.   Deconvolution analysis of the TACs was used to improve separation of the arterial and portal venous phases of total liver blood flow.

28.   In addition, this method takes account of tracer recirculation and therefore allows analysis of the deconvoluted curves by area under the curve as a measure of blood flow.

29.   Several investigators have attempted to define the portal venous and hepatic arterial contributions to total liver blood flow by non-invasive means including ultrasound and radionuclide angiography.
