When I get a nosebleed I immediately pinch my nostrils closed and after about 3 minutes I let go and the bleeding has stopped and there is no blood piled up in my nostril? Where has the blood gone?
In: Biology
Two possibilities:
1. You have successfully pinched off the blood vessel to prevent further bleeding (the pressure you create is greater than the pressure driving blood out of the vessel) or at least has greatly slowed down the bleeding. This allowed for clotting factors/platelets to close the hole that the bleeding came from.
2. The blood has now flowed down the back of your nasal cavity and drips down your throat. The reason that the bleed has stopped is simply that enough time has elapsed that a clot has sealed off the blood vessel tear.
