Clutches and Bands in an Automatic Transmission. In the last section, we discussed how each of the gear ratios is created by the transmission. For instance, when we discussed overdrive, we said:
Materials move in opposite directions: reabsorption moves materials into the blood, whereas secretion removes them from the blood. Blood pressure in the glomerulus is _______ than in other capillaries due to the relatively large diameter of ________ arterioles. higher; afferent.
1 Essentially reabsorption in reverse, where substances move from peritubular capillaries or tubule cells into filtrate. 2  Tubular secretion is important for: 3  Disposing of substances not already in the filtrate. 4  Eliminating undesirable substances such as urea and uric acid.
