You do it before a lab so as to prevent contamination of the materials. You might have things on your hands that might contaminate the experiment and the research. You do it after because you don't want to have things from your experiments on your hands because that can be extremely dangerous.

The condition in which the heart does not circulate blood at a satisfactory rate is known as:_______
Zielflug [23.3K]

The condition in which the heart does not circulate blood at a satisfactory rate is known as <u>heart failure.</u>

<u></u>

<h3>What is heart failure?</h3>

The name of this condition can be a little confusing. When you have heart failure, it doesn't mean your ticker stopped beating. What's really going on is that your heart can't pump blood as well as a healthy one.

The chambers of your heart may respond by stretching to carry more blood to pump through your body. They may become stiffer and thicker. This helps keep blood moving for a while, but in time, your heart muscle walls may get weaker.

<h3>What Causes It?</h3>
  • Coronary artery disease is a problem with the arteries that supply blood and oxygen to your heart. It means less blood flows to your heart muscle. When the arteries narrow or get blocked, your heart becomes starved for oxygen and nutrients and can't pump as well.
  • Heart attack may happen when a coronary artery is blocked suddenly, which stops the flow of blood to your heart muscle.
  • Cardiomyopathy is damage to your heart muscle. It can be caused by artery or blood flow problems, infections, and alcohol and drug abuse. Other diseases or genetic issues can also bring it on. Make sure your doctor knows your family's health history.
