An attempt to correlate functional and morphological data for the gastric parietal cells.
In fed rats, acid production was estimated to be 7 X 10(8) molecules of HCl per cell per sec or 5 X 10(5) molecules per sec per mu2 of secretory surface. In stimulated frog mucosa the corresponding values were 3 X 10(8) molecules of HCl per cell per sec 2 X 10(5) molecules per sec per mu2 or secretory surface. The generous assumptions used in making these estimates could have led to large errors.
