Sinoatrial node part of the autonomic nervous system adjusts the heart rate and the arteriole diameter to regulate blood pressure through negative feedback
The SA (sinoatrial) node is generates an electrical signal that can causes the upper heart of the chambers (atria) to contract. The signal and then passes through the AV (atrioventricular) node to the lower of the heart chambers (ventricles), causing them to contract, or to pump. The SA node is considered the pacemaker of heart.
The sinus node continuously generates electrical impulses, thereby setting the normal rhythm and also rate in a healthy heart. Hence, the SA node is also referred to as the natural pacemaker of the heart

Studies show us that multitasking is not effective and makes us more prone to error. That's why multitasking for humans doesn't work.

Multitasking is doing multiple work at once. Human brain, our brain, is incapable of performing multiple tasks at the same time. This happens even after extensive long training. It's because our brain isn't hardwired to do multiple tasks. Study on neurological science shows us that the human brain is not able to focus on two things at once. The other study shows that the human brain can only do two tasks at the same time, because it only has two hemispheres available for the tasks.
