Who made a electrical device called a pacemaker for the human heart?
John hopps invented the first external pacemaker. Later Earl Bakken improved this pacemaker by making it battery powered. And then Wilson Greatbatch invented the first implantable pacemaker!
How does the human heart operate?
Human heart is myogenic in nature. It consists of sinoatrial node in the right atrium below the endodermis. this node initiates the electrical impulses in heart. As it is initiator it is also called pacemaker of heart. The atrioventricular node gathers the impulses and transmits them to the purkinje fibres via. bundle of his-tawara. As atrioventricular node collects all the impulses it is also called pacesetter of heart.
How much does a pacemaker weigh?
The human heart weighs anywhere from 0.551155 pounds to 0.771617 pounds.
What are pacemaker cells in the human body?
They Are A Special Group Of Nerve Cells. Nerve Signals From The Brain Control The Pacemaker, Making It Go Faster Or Slower When Required. Specialist cells in the heart which have autorhythmicity.
What to human ribs protect?
Internal organs such as the lungs and heart.
What would the human heart be classified as?
An internal organ if that's what you mean.
What is the 4 largest internal organ in the human body?
lungs, heart , liver, kidney
Should humans be concerned for their heart?
Yes, they SHOULD actually because the human heart is the main internal organ in our body.
What organ in the human body can be fixed with a pacemaker?
the ear
Where is a pacemaker placed in the body?
The pacemaker of the heart is the sinoatrial (SA) node, which is located in the upper right atrium, just below the entrance of the superior vena cava. The SA node is responsible for setting the heart rate for the heart.
How do your heart and lungs keep you alive?

What is primary pacemaker of heart?
The human heart started out as a enlarged blood vessel that appears as two blood vessels coming together. The heart is comprised of four chambers two small chambers called the atrium and two large chambers known as the ventricles. There are several tissue layers of the heart. The internal layer is known as the endocardium the muscle layer is known as the myocardium, and the outer layer is known as the epicardium. There is an outermost sac called the pericardium that makes up a cavity in the thoracic cavity known as the mediastinum. There are specialized conducting cells or tissue within the myocardium of the heart. These specialized tissue performs the electrical conduction of the heart. The first is the sinoatrial node or the SA node found in the right upper atrium, the next one is the atrioventricular node or the AV node found in the right lower atrium. Then there is a group of this tissue known as the bundle of His or AV bundle (found in the wall of the ventricular septum (the dividing wall between the two ventricles)) and then the right and left buncle branches ( found also in the wall of the intraventicular septum and the outer ventricles) until you come to the purkinjie fibers at the end in the walls of the ventricles. The primary pacemaker of the heart is the SA node and depending on what is going on with the heart as far as damage the secondary pacemaker is the AV node, however the bundle of His could become a pacemaker site or the right and left bundle branches. The lower you go in the pacemaker sites the slower and less able the heart is to conduct proper electrical stimulation to effect the heart conduction and contraction (beat of the heart).
