Figure 1. Rates of (A) umbilical uptake and (B) uteroplacental consumption or production of glucose (i) lactate (ii) and oxygen(iii).

Rates were expressed as weight-specific values (μmol min⁻¹ kg⁻¹) per kg fetal weight (A) or kg placenta (defined as total placentome mass) (B). Fetuses were infused with either saline (n = 8) or cortisol (n = 8). Significant differences are: *P < 0.02; ^†P < 0.05; ^‡P < 0.039 (Student's unpaired t test).
