Problem description:

After watching the matador stab the cow in the heart with his sword on TV, the cow began to vomit blood and then pulled it out immediately. It's strange why blood is spit out and not left in the body.

Analysis:

The answer upstairs is irrelevant.

Cattle's heart blood vessels will instantly expand and contract by 80%, which is easy to cause problems and vomiting blood is inevitable. Blood comes from the heart and naturally radiates from it. The throat is the easiest place to decompress. As the saying goes, you get the moon first by being close to the water ~ ~

The blood from the heart is connected with the intestine (otherwise, how can nutrition reach the heart? ), inserted into the heart of a cow, the arterial blood in the heart will be ejected, and it will come out of the lungs with great strength. The nose and mouth are also connected together, so they will vomit.
