Noah's principle is a concept that comes from the Biblical story found in the old testament where God gave Noah instructions to build an ark to save him and his family .
The concept here is that God did not tell Noah when it was going to rain. The people of the day most probably mocked and derided Noah as a time waster or a fool. That is, until the flood came. The " fool" had been wiser all along.
An Application is this. Google gives everyone who does online business "suggestions" and "guidelines" but not everyone chooses to listen. Google rarely, if ever, tells us when they will put the guidelines into action.

Moral: Heed and prepare even if the outcome tarries.

The body system responsible for circulation of the blood, including the heart, arteries, veins and capillaries, is called the cardiovascular system
<h3>Cardiovascular system</h3>
To supply the lungs with oxygen, the circulatory system (cardiovascular system) pumps blood from the heart. Following that, the heart pumps oxygen-rich blood through arteries to the rest of the body. Poor in oxygen blood is returned to the heart by veins to restart the circulatory system. The cardiovascular system plays a crucial role in supplying your body with oxygen and nutrients as well as removing waste. Your cardiovascular system is how your cells obtain the nutrients they require to function properly. It is crucial to take care of your heart by exercising, eating a healthy diet, and maintaining under control your blood pressure and cholesterol.
