What is ❤️?

The heart (❤️) is a vital organ responsible for pumping blood throughout the body, delivering oxygen and nutrients to tissues and removing waste products. Its primary function is achieved through a rhythmic cycle of contraction and relaxation. This cycle involves two main phases:

• Systole: The phase where the heart muscle contracts, pumping blood out of the chambers and into the arteries.
• Diastole: The phase where the heart muscle relaxes, allowing the chambers to fill with blood.

The heart is composed of four chambers: two atria (right and left) and two ventricles (right and left). Blood enters the heart through the atria and is then pumped into the ventricles, which subsequently pump it out to the lungs and the rest of the body. The heart also contains valves, which ensure that blood flows in only one direction.

Maintaining a healthy heart involves lifestyle choices, regular exercise, a balanced diet, and avoiding smoking. Heart disease, including conditions like coronary artery disease, heart failure, and arrhythmias, can significantly impact quality of life and longevity. Understanding Heart Anatomy, Heart Function and Heart Disease is crucial for promoting cardiovascular health.
