How does the heart supply itself with blood?
Mehmet Oz, MD, Cardiology, answeredThe heart gets its own supply of blood from the coronary arteries. The two main coronary arteries (right and left) and their branches supply blood throughout the heart muscle. This animation explains how these arteries transport blood.

How much blood does your heart handle each day?
Discovery Health answered
Your heart pumps approximately 2,000 gallons (7,571 liters) of blood each day through its chambers. Of course, people cannot hold that much liquid in our bodies, so the heart just keeps circulating blood, over and over.
Besides pumping that much blood, the heart also beats about 100,000 times each day to supply every cell with oxygenated blood. No matter how many tissues and organs the heart supplies with oxygen-rich blood, it looks out for No. 1 first, making sure it gets the blood it needs.
How does cold weather affect my heart?
Mehmet Oz, MD, Cardiology, answeredFrigid temperatures thicken your blood and constrict your arteries, which elevates your blood pressure. Those changes are a one-two punch for your heart, leaving it more vulnerable to a heart attack. Add overexertion (such as shoveling the driveway), and you’re primed for a visit to the ER. So take it easy before starting physical activity, and warm up slowly. If you must do hard work, such as shoveling snow, work in small intervals, taking breaks often. Better yet, if you are over 50 or know you are at risk for heart disease, ask someone else to do it, or invest in a snow blower.
