Households with lawns or gardens must factor in the amount of water sprinkled on grass, flowers and vegetables. Outdoor watering uses 5 to 10 gallons per minute. So in 10 or 20 minutes, you may use 100 gallons â the amount industry experts estimate is used by an average person each day for all personal water needs!
Cardiac conduction is the driving force behind the cardiac cycle. This cycle is the sequence of events that occur when the heart beats. During the diastole phase of the cardiac cycle, the atria and ventricles are relaxed and blood flows into the atria and ventricles. In the systole phase, the ventricles contract sending blood to the rest of the body.
Cardiac catheterization (also called cardiac cath or coronary angiogram) is an invasive imaging procedure that allows your doctor to see how well your heart is supplied by blood vessels. During the test, a long, narrow tube, called a catheter, is inserted into a blood vessel in your arm or leg and guided to your heart with the aid of a special X-ray machine.
