The marginal hematomas form two raised ridges on either side of the (1) (see Figs. 38/39). The clotted blood in the hematomas begins to degenerate and is absorbed by the overlying (2) as (3). The marginal hematomas usually have a greenish colour due to the presence of (4) pigment (a breakdown product of hemoglobin). In the cat, small marginal hematomas only form towards the end of pregnancy (from about day (5)) and are (6) in colour. The cat also has small hemorrhages (so-called (7) hematomas) scattered through-out the placental region; they are also (6) in colour and are absorbed as (3).
