Abstract
After prolonged hypokinesia for 80–100 days considerable disturbances of the nutritive circulation were observed in experiments on rats: reduction of the network of true capillaries, emptying of the terminal arteries and arterioles, direction of the terminal blood flow mainly along the developing network of arteriovenous anastomoses, by-passing the nutritive vessels. A tendency was noted for the buffer bases to be low in the venous blood and for respiratory alkalosis to be present in the arterial blood. The hemorheological stages were not significant.
