How many valves does a human heart have?

The heart is such an amazing organ!

mapt (mapped spelled as mapt) mitral aortic pulmonary/pulmonic tricuspid

There's also four chambers in the human heart. The right and left atria, and the right and left ventricles. On topic, it's sad when young people blow out their heart valves with their drug addictions. Sadder yet, is so often after having their valves replaced (almost always at taxpayer expense), they resort to their filthy drug habits that yields the same results, and almost always is a death sentence.
