What is Heart?

The heart is a fist-sized muscular organ that pumps blood and oxygen throughout the body. The heart is located in the middle of the chest, slightly to the left, between the lungs. It’s made up of three layers of tissue: Epicardium, Myocardium, and Endocardium. The heart also has four chambers: two atria and two ventricles. The heart’s chambers are separated by valves that direct the flow of blood. The heart has four valves: The mitral valve, tricuspid valve, aortic valve, and pulmonary valve.

The heart beats due to electrical impulses that move blood through the chambers. The average adult heart rate is 70 beats per minute at rest. The brain and nervous system control the heart’s function. The heart’s main functions are moving blood throughout the body, controlling heart rate, and maintaining blood pressure.

The heart is a vital organ in the human body and is responsible for pumping blood throughout the circulatory system. The heart structure consists of four chambers: two atria and two ventricles, each with its specific function in the blood circulation process. The atria receive blood from the body and the lungs, while the ventricles pump blood out to different body parts.

Through rhythmic contractions, the heart ensures that oxygen-rich blood is delivered to all tissues and organs of the body and helps sustain life. In this article, we will read about some interesting facts about heart.
