The human heart is the most principle organ of the entire body. This article will signify some of the most fascinating facts about how the heart works.
The average heart beat rate of an adult is 72 times per minute. If we go on further, the heart beats 100,000 times a day; 3,598,000 times a year; and 2.4 billion times during your whole life. This is some math!
During an average lifetime, the heart pumps about 1.5 million barrels of blood. This amount can be used to completely fill around 200 train carts. If the same amount of coal is placed in those carts, they would have been extensively expensive but the blood is free of cost; a great gift of God.
The heart pumps oxygenated blood via the aorta at about 1.6km per hour. By the time blood reaches the capillaries, it is travelling at a sluggish pace of about 42 inches per hour. This slow pace is very important because the gas exchange occurs through the capillaries. It is the unhurried speed that allows an ample time for the efficient absorption of oxygen by the cells and the release of carbon dioxide from the cells to the blood. Laughter is extremely beneficial for the heart working. Laughter can cause 20% more blood to flow through your entire body which in turn, relaxes the walls of the vessels. One study confirmed that when people watch a funny movie, their blood flow increases. Therefore, from now onwards, keep laughing so that your heart becomes stronger and your heart vessels grow in strength.People can actually die from a broken heart. After going through a dreadful loss or painful event, certain stress hormones are secreted by the body into the blood stream. These hormones can cause a heart attack which can lead to heart failure in some unfortunate cases.There are a lot of marked differences between the hearts of a man and a woman. A man’s heart weighs about 10 ounces, whereas a woman’s heart weighs just about 8 ounces. The woman’s heart is smaller than man’s heart. The woman’s heart show less obvious signs of trouble. When they are on the verge of a heart attack, they feel nausea, and their shoulder aches rather than the characteristic pain in the chest. The heart is the power organ. It pumps blood to almost all of the body cells which are about 75 trillion in number. Corneas are unlucky in this regard because they are the only part of the body which does not receive blood.Sources
