1. The heart is a vital organ in the human body responsible for pumping blood throughout the body, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other waste.

2. It is about the size of a fist and weighs approximately 310 grams. It's located in the chest, between the lungs, slightly to the left of the midline.
3. The heart is made up of four chambers: the left and right atrium, which receive blood, and the left and right ventricles, which pump blood.
4. The average human heart beats about 72 times per minute. Over the average lifespan, this equates to approximately 2.5 billion heartbeats.
5. The heart is a muscular organ, and the muscle that it's made up of is called cardiac muscle, which is a type that's found only in the heart.
6. The heart functions through an electrical system that controls the pace of your heartbeats. Irregularities in this electrical system can result in various heart conditions, such as arrhythmias.
7. Your heart pumps around 1.5 gallons of blood every minute. This equates to around 2,000 gallons per day, and nearly 1 million barrels of blood during an average lifetime.
8. Exercise is important for heart health. It helps maintain the heart's ability to pump blood efficiently, keeps our weight under control, and reduces the likelihood of heart disease.
9. There are many conditions that can affect the heart's function, including heart disease, heart attacks, heart failure, and arrhythmias. Many of these can be prevented or managed through healthy lifestyle choices.
10. A healthy diet is also crucial for heart health. Foods rich in omega-3 fatty acids, such as fish, as well as fruits, vegetables, and whole grains, can help protect against heart disease.
