48. Which of the following statements is true regarding Renal Function and the filtration of molecules? A. Large molecules like Glucose are not filtered into the renal tubules because Glucose is too big. B. Glucose molecules are ultimately secreted into the renal tubules; that is why Glucose is found in the urine of a normal healthy person. C. Plasma Proteins are filtered into the renal tubules but are rapidly reabsorbed; that is why very little protein is found in the urine of a healthy person. D. Plasma Proteins are simply too big to be filtered into the renal tubules; that is why very little protein is found in the urine of a healthy person.

1. Functions of the Urinary System A. Kidneys regulate blood levels of several ions, most importantly (Na+), (K+), _(Ca2+), _(Cl-), and _(HPO42-). B. Kidneys regulate blood pH by secretion of and reabsorption of C. Kidneys regulate blood volume by conserving or eliminating D. Kidneys regulate blood pressure by secreting the enzyme which activates the RAA pathway that increases blood pressure. E. Kidneys help maintain a relatively constant blood osmolarity of F. Kidneys produce _mOsm/liter. (active vitamin D) and - the hormone that stimulates RBC production. G. Kidneys can use glutamine (amino acid) to synthesize H. Kidneys excrete wastes such as from deamination of amino acids, from catabolism of hemoglobin, from breakdown of creatine phosphate, and from catabolism of nucleic acids. 2. Matching: Kidney A.
