21. Blood travels through the arterioles and moves into the capillaries where gas exchange can occur. 22. Atherosclerosis, by definition, affects only medium and large arteries ( excluding arterioles ). 23. Immediately following the arterioles are the capillaries. 24. Another determinant of vascular resistance is the " pre-capillary arterioles ". 25. The straight arterioles are peritubular capillaries, specifically those that surround the loop of Henle. 26. In the arterioles , capillaries, and venules the Womersley numbers are less than one. 27. Affects capillaries, venules, or arterioles . 28. Proposed procedures for the neurodegeneration are than Narrower arterioles and wider venules have been reported. 29. Arterioles have the greatest collective influence on both local blood flow and on overall blood pressure.30. Constriction of the afferent arterioles causes a decrease in the intraglomerular pressure, reducing GFR proportionally.
