What is heart and explain its function?
Heart: The human heart is one of the most important organs responsible for sustaining life. It is essentially a muscle, about the size of a clenched fist. The human heart functions throughout a person’s lifespan, pumping almost 200 million litres of blood. A human heart roughly beats 2.5 billion times during a human lifespan, making it one of the most robust and hardest working muscle in the human body. Besides humans, most other animals also possess a heart that pumps blood throughout their body. Even invertebrates such as grasshoppers possess a “heart”, though they don’t function the same way a human heart does.
Function of the Heart
- The function of the heart in any organism is to maintain a constant flow of blood throughout the body. This replenishes oxygen and circulates nutrients among the cells and tissues. And because the human heart is a homologous organ, it functions no differently from any other vertebrates that possess a heart. Following are the main functions of the heart:
- One of the primary functions of the human heart is to pump blood throughout the body.
- In the process, the human heart also aids the body’s transport system – blood, by delivering oxygen, hormones, glucose etc to various parts of the body.
- The heart also ensures that adequate blood pressure is maintained.
