Anticoagulants Memes

The science here is hilariously accurate! Menstrual blood contains anticoagulant compounds that prevent it from clotting inside the uterus (just like The Flash zooming around). Meanwhile, regular blood outside the body quickly activates clotting factors and slows down (poor exhausted Flash). This difference is due to the endometrial tissue releasing fibrinolytic enzymes that break down clots. Without these enzymes, menstrual blood would form painful clots that couldn't exit properly. Biology is wild—it's basically running a monthly anti-clotting protocol that would make any hematologist jealous!
