血体是卵泡排卵后形成的一种临时结构。创伤愈合后，随后的结构称为黄体（进而成为白体退化）。

The corpus hemorrhagicum ("bleeding corpus luteum") is a temporary structure formed immediately after ovulation from the ovarian follicle as it collapses and is filled with blood that quickly clots. After the trauma heals, the subsequent structure is called the corpus luteum (which in turn becomes the corpus albicans before degenerating.)Sometimes during ovulation small blood vessels rupture, and the cavity of the ruptured follicle fills with a blood clot, a corpus hemorrhagicum.
