Answer:
Structure of the Human Heart
The human heart is about the size of a human fist and is divided into four chambers, namely two ventricles and two atria. The ventricles are the chambers that pump blood and atrium are the chambers that receive blood. Among which both right atrium and ventricle make up the “right heart,” and the left atrium and ventricle make up the “left heart.” The structure of the heart also houses the biggest artery in the body – the aorta.
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 liters 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 do not function the same way a human heart does.
