Complete 4. the second column in Table 16.4, page 220. Use an X to indicate that the substance is at the locations noted. Tubular Reabsorption 1. When the filtrate enters the proximal convoluted tubule, it contains glucose, amino acids, urea, water, and salts. Some water and salts remain in the nephron, but enough are passively reabsorbed into the peritubular capillary to maintain blood volume and blood pressure. Use this information to state a way kidneys help maintain homeostasis 2. The...

This is a question for Toxicology, it asks about the absorbtion, biotransformation and excretion of a chemical in the human body, Chemical B is found in smoke from burned plant materials and fossil fuels. It is a fairly large polycyclic aromatic hydrocarbon and has a very high Kow. Although high levels are found commonly in certain tissues, no adverse effect has been determined in humans or laboratory animals. For the following questions about the metabolism of this chemical, assume that...
