(7 points) In the process of [a] feedback, [b] cells monitor NaCl concentration in the lumen of the [c] convoluted tubule. High NaCl concentrations sensed by these cells trigger the release of [d] which binds to smooth muscle cells on the [e] arteriole causing muscle [f]. The resulting change in blood flow to the renal corpuscle reduces the [g] rate and slows flow through the nephron.

In the kidney, the highest concentrations of urea, Na+ and Cl¯ would be found nearest the:

Oxygen moves from the ____ to the ____, which is from high concentration to low concentration.

Microvilli are:

Which of the following would normally be found in sinusoids?

An alternative name for vasopressin is antidiuretic hormone. By either name, the molecule is a peptide hormone that:

(10 points) Gastric pits, which are part of the stomach [a] (layer), contain specialized cells called [b] cells that secrete protons from their apical membranes. These ions originate when the enzyme [c] converts [d] and [e] into [f] and [g]. Movement of this ion across the apical membrane requires a(n) [h]ase that exchanges a [i] ion from the extracellular space for a [j] ion in the cytoplasm.

GLUT2 is a high capacity facilitated glucose transporter found in the plasma membranes of hepatocytes. It is also found in:

In the renal corpuscle, ____________ generates a(n) ___________ force to drive fluid out of the glomerular capillary.

a) What is the action of the lateral rectus muscle? b) What is the origin of the fibularis longus?
