Microvilli are:

(8 points) Following hypovolemic shock, [a] cells on the afferent arteriole sense a reduction in pressure and release the enzyme [b]. This molecule cleaves a short peptide out of the inactive [c] to make the active [d], which is then converted to [e] by an enzyme in the lungs called [f]. The final molecule will [g] blood pressure by causing the contraction of arterial [h] muscle. 

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

Our mouth “waters” when the ___________ branch of the autonomic nervous system stimulates __________ cells to transport ________ across the glandular epithelium.

Where in the accompanying figure showing a portion of a kidney, would you expect to find the distal convoluted tubules?

The Pco2 in the alveolar space is normally about 40 mmHg. After breathing in and out rapidly (hyperventilating) alveolar Pco2 levels may fall dramatically causing arterial Pco2 to _____ and _____ the urge to breathe.

(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.

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

List the muscles of the rotator cuff 

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