外溢的母体血液从母体隔膜尖端的毛细血管和较大的血管中逸出，是妊娠最后三分之一羊子叶中央凹陷的特有色素沉着的原因。该区域的绒毛上皮积极参与母体红细胞的摄取和随后的分解，这可能是胎儿在宫内最大生长时期的重要铁源。
Extravasated maternal blood, which escapes from capillaries and larger blood vessels within the tips of the maternal septa, is responsible for the characteristic pigmentation of the central depression of the ovine cotyledon in the last third of pregnancy. The chorionic epithelium of this region is actively engaged in the uptake and subsequent breakdown of maternal erythrocytes, which may represent an important source of iron for the foetus during the period of maximum intra-uterine growth.
