The glomerulus filters water, wastes (urea), glucose, and salts out of the blood. The proximal convoluted tubule actively transports glucose, amino acids, and salts across membranes and returns them to the blood. Loop of Henle concentrates salts by reabsorbing water. The distal convoluted tubule reabsorbs sodium, water, and the remainder of glucose.
