The Action of the Heart. 1  The blood enters the atria to fill it, called the Arterial Diastole. 2  The sino-atrial node is present in the right atrium. 3  It generates a nerve impulse. 4  This cause the contraction of the atria called the Atrial Systole.

1 An average heart pumps about 2.4 ounces (70 milliliters) of blood per beat of heart. 2  If 72 beats occur per minute, then about 1.3 gallons (5 Liters) of blood is pumped per minute. 3  About 1,900 gallons (7,200 Liters) of blood is pumped per day.

An average man's heart weighs 10 ounces, and a woman's heart weighs only 8 ounces. Women's hearts make up for their smaller size by beating a little faster. The average heart rate of a man is 70 beats/minute, and that of a woman is 78 beats/minute.

1 About 1,900 gallons (7,200 Liters) of blood is pumped per day. 2  This adds up to almost 700,000 gallons (2,628,000 Liters) of blood per year and about 48 million gallons (184,086,000 liters) by a life span of 70 years.

By Dr. CHRISTOPHER MAGOVERN. 1. Your Heart is a Pump. Your heart really isn't just a pump, it's a SUPER pump. Every part of your body needs oxygen to survive, and your heart pumps oxygen-rich blood to every organ in your body, every minute, of every day. For its size, your heart is a remarkably strong pump … the pressure it generates is strong enough to squirt blood thirty feet across a room.

This is the power of a typical human heart, but it's different for everyone. The average heart beats about 75 times per minute, which is about five liters of blood per minute. Although this isn't much, it enables the heart to complete a tremendous amount of work in a person's lifetime.

About two-third of the heart lies to the left side of our midline of the body and about one-third to the right side. It appears as a cone-shaped and hollow muscle mass. The heart is a double pump made up of cardiac muscles. It pumps the blood throughout our body by repeated rhythmic contractions and relaxations.

It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%). 1.3 W. Sadr, Farokh S. Heart Matters. A normal heart in an average sized person will pump 4 to 5 liters of blood per minute. And the average heart will beat almost 4 million times per year [sic, they probably mean 40 million -- ed.]. It is estimated that the energy required to continuously pump blood at these rates is almost 5 watts of power per hour [sic, watts of power is fine, watts of power per hour is a non sequitur -- ed.]..

1 The blood pressure in the atria is more than in the ventricles. 2  The AV Valve opens and the blood is forced into the ventricles. 3  The impulse then reaches the atrio-ventricular node. 4  A delayed impulse of about 0.2 seconds helps in filling the ventricles, called the Ventricular Diastole.

4. Your Heart is Not on the Left Side of Your Chest. Although most of us place our right hand on our left chest when we pledge allegiance to the flag, we really should be placing it over the center of our chest, because that's where our hearts sit.
