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.

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.
The Heart: Conduction System The heart pumps blood through the body This is accomplished by contraction and relaxation of the cardiac muscle tissue in the myocardium layer. Intercalated discs allow impulses to travel rapidly between adjacent cells so they function as one rather than individual cells. Cardiac Muscle Tissue Conduction System Continuedâ¦.
