Which organ of the human body works 24 hours?

The human heart is an organ that works continuously 24 hours a day, seven days a week, throughout a person’s entire life. It is responsible for pumping blood to all parts of the body, delivering oxygen and nutrients to cells and removing waste products. This constant pumping action ensures that vital organs and tissues receive the necessary oxygen and nutrients to function properly. The heart never rests and is a critical component of the circulatory system, maintaining the flow of blood to sustain life.
