Explanation:
The myocardium is the muscle tissue of the heart, a muscle responsible for pumping blood through the circulatory system through contraction. It receives a part of the large volume of blood that passes through the atria and ventricles. A system of arteries and veins (coronary circulation) provides the myocardium with oxygen-rich blood and allows the return of venous or oxygen-poor blood to the right atrium. The right coronary artery and the left coronary artery are the branches of the aorta responsible for the blood supply.

Weather is the day-to-day changes in the atmospheric conditions of regions. Weather parameters are usually temperatures, humidity, rainfall, air pressure, and etcetera. These vary greatly every so often on a daily basis. Climate, on the other hand is categories into arctic, subarctic, subterranean, Mediterranean, temperature, equatorial, and etcetera.
Explanation:
When weather is studied for a long time, such as for over 30 years, general weather patterns can be discerned that will determine the climate of the region. These general weather patterns over a region will make up its climate. Climate does not change considerably. Therefore the climate of a region remains steady. If the climate of a region changes it does so ever so slightly over millennia and would change because of phenomena like earth’s tectonic plate movements, space phenomenons, and human activities.
