Fig. 2. Hct changes in response to graded Ringer solution addition or blood removal
in day 15 embryos. (A) Effect of whole blood removal on Hct. Asterisks

repeated Ringer solution injection on Hct in day 15 embryos. Despite acute
blood volume increases by up to 115%, Hct did not change significantly from
control. Mean values ± 1 s.e.m.
