Complete the following sentences to explain the primary steps in urine formation. Then place each statement in chronological order based on when it occurs in this sequence. Labels con be used more than once. During ______, nutrients and ______ move across the walls or the _____ into the _____ and water follows by ____. During ______, potentially harmful molecules such as uric acid, ammonia, and _____ ions are actively secreted from the ______ into the ______. During ______. small particles present in blood move out of the glomerulus, remaining inside the glomerular _____ Small molecules like water, salts, and _______ pass through the glomerular ______. but blood cells and _____ are too large and remain in the blood.Explanation / Answer
During tubular reabsorption, nutrients and salts move across the walls of the convuluted tubules into the peritubular capillary network and water follows by passive diffusion.
During tubular secretion, potentially harmful molecules such as uric acid, ammonia, and hydrogen ions are actively secreted from the peritubular capillary network into the convuluted tubules.
During glomerular filtration, small particles present in blood move out of the glomerulus, remaining inside the glomerular capsule. Small molecules like water, salts and glucose pass through the glomerular wall, but blood cells and proteins are too large and remain in the blood.
