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.
Tubular secretion. Diagram showing the basic physiologic mechanisms of the kidney and the three steps involved in urine formation. This is a diagram that shows the basic physiologic mechanisms of the kidney and the three steps involved in urine formation, namely filtration, reabsorption, secretion, and excretion.
