Want this question answered?
The electrical impulse reaches all the muscle tissue in the ventricles, and the ventricles contract. This electrical conduction pattern occurs approx. every 0.8 seconds.
-the atriums are smaller then the ventricles. -the atriums have thinner muscle tissue. -the atriums only have to pump blod to the ventricles. -the ventricles are larger in size. -the ventricles have larger muscle tissue. -the ventricles have to pump blood to either the lungs or around to the rest of the body. hope this helpedddd ;D xox <3 Bellaaaa
The nervous system conducts electrical signals from one structure to another. For example from the brain to the muscles for movement.
TRUE
It is the atrioventricular bundle or bundle of His

There are two muscles that divide the chambers of the heart. The right and left ventricles are divided by the interventricular septum and the right and left atria are divided by the interatrial septum.
The brain is protected by cerebrospinal fluid (CSF). It flows through the ventricles in the brain and between the meninges, the layers of tissue between the brain and the skull. CSF supports and cushions the brain from blows.
