THE HEART'S LITTLE BRAIN

To define it in scientific terms, the heart is considered a key organ because it is the central component of the circulatory system, which plays a vital role in sustaining life.

cent at the Department of Neuroscience, Karolinska Institutet, Sweden, who led the study: "This 'little brain' plays a key role in maintaining and controlling heartbeat, similar to the brain, which helps regulate rhythmic functions like breathing, sense of hunger and locomotion." This study also further showed how researchers have discovered several types of neurons in the heart that have similar functions and also a small group of neurons that have 'peacemaker properties'. So, how does this 'little brain' help us in our everyday lives, in what ways does it impact our lifestyle, and how do we identify this little brain in our heart?

2 The heart pumps blood throughout the body, delivers oxygen and nutrients to every cell, and helps release carbon dioxide from the body.

3 It works as a powerful pump that helps in circulating blood even to the smallest capillaries, and the concentrated contraction and relaxation of the heartbeat help maintain blood pressure.

4 The heart is also connected to the lungs, and it ensures that the deoxygenated blood is sent to the lungs to pick up oxygen, which is then distributed to the rest of the body.

5 The heart's rhythmic beating is closely tied to the nervous system and endocrine system, which helps regulate our metabolism, temperature, and hormone delivery.

6 The heart can adjust the pumping rate and strength, based on the body's needs while resting, exercising or when one is stressed out.
