Blood Destruction during Exercise
A definite increase in the percentage of reticulocytes occurs after exercise in animals previously kept to a sedentary life. Concomitant changes in the hemoglobin percentage, plasma-cell ratio, and red count offer evidence in addition to that already reported by the author of the occurrence of an increase in blood destruction under such circumstances. Replacement by transfusion of blood destroy...
متن کاملCellular aggregation and destruction during blood circulation and oxygenation.
Platelet and leucocyte aggregation and severe haemolysis may occur in blood during the preparation of an extracorporeal circuit for open-heart surgery. Experiments with dog blood showed that both processes result from bubble oxygenation but not from circulation of diluted blood and that they appear to be inhibited by the presence of acid citrate dextrose and heparin, or citrate phosphate dextro...
متن کاملLeg blood flow during exercise in man.
1. An indicator-dilution technique was used to determine human leg blood flow at rest and during exercise. The method is based on the infusion of Indocyanine Green into the femoral artery with blood sampling from the femoral vein at the level of the inguinal ligament. Evidence for mixing of dye and blood is presented, based on the finding of equal dye concentrations at two different sampling le...
متن کاملCerebral blood flow and metabolism during exercise.
During exercise regional cerebral blood flow (rCBF), as blood velocity in major cerebral arteries and also blood flow in the internal carotid artery increase, suggesting an increase in blood flow to a large part of the brain. Such an increase in CBF is independent of the concomitant increase in blood pressure but is modified by the alteration in arterial carbon dioxide tension (PaCO(2)). Also, ...
متن کاملRegulation of coronary blood flow during exercise.
Exercise is the most important physiological stimulus for increased myocardial oxygen demand. The requirement of exercising muscle for increased blood flow necessitates an increase in cardiac output that results in increases in the three main determinants of myocardial oxygen demand: heart rate, myocardial contractility, and ventricular work. The approximately sixfold increase in oxygen demands...
