Answer:

prevent blood from flowing backward

Explanation:

think of the heart as the panama canal. There are four chambers, the atria and the ventricles. It goes from right atrium to right ventricle, and then to the lungs, where it gets oxygen, and then into the left atrium and finally into the left ventricle which pumps the blood through the aorta into the systemic circulation. Valves prevent backflow of the blood, they open and close at difference stages of the heart cycle.

Intuition requires clear thinking and reasoning through a problem

lutik1710 [3]

The correct answer is; False.

Further Explanation:

Intuition is not when there is reasoning through a problem someone has or does it require clear thinking. Intuition is when a person has a feeling about something or even an understanding that does not have a specific reason nor needs reasoning.

A decision is when a person will have to have reasoning through a problem that they have. They will have need to think clearly when making the decision as it could impact their future.

Intuition is more of a gut feeling and something that we just have in our thought process. One example of intuition is a mother's intuition, a mother can just know when there is something wrong with their child.
