The Heart: The Body's Little Engine:
The heart is a very important organ in the human body. It is pear-shaped and located in the center of the chest, slightly tilted to the left. The heart's primary function is to pump blood to all parts of the body.
Blood:
Carries the oxygen and nutrients the body needs to live. When the heart beats, it sends blood to the lungs to pick up oxygen, which is then transported to all parts of the body.
Heart Structure:
The heart consists of four chambers: two upper chambers called atria, and two lower chambers called ventricles. This arrangement helps blood flow regularly.
To maintain a healthy heart, you should eat a healthy diet, exercise regularly, and avoid smoking.
In short, the heart is the little engine that keeps the body functioning efficiently and energetically every day.
