What else can I help you with?
Do the ventricles contract at the apex or at the base of the heart?
Not really sure what you mean by the base, the ventricles contract from the Apex (which is at the bottom) upwards.
What makes ventricles contract?
Purkinje Fibers actually makes the ventricles contract.
What happen after depolarization of the ventricles?
The ventricles contract.
When atria relax ventricles do what?
When relaxed, the atria expand, and then the ventricles contract.
What are the fibrous structures in the heart that prevent prolapse of the cuspid valves?
Chordae tendineae - attached to the valves between both atria and ventricles... these structures are attached to papillary muscles in the bottom of the ventricles. these contract when the valves contract, this keeps the blood from going back up into the atria.
Do atria contract before the ventricles?
Yes, atria contracts before the ventricles.
When doe the ventricles contract?
Systole
What does the atrioventricular node cause to contract?
The atrioventricular (AV) node causes the ventricles of the heart to contract. It serves as a critical relay point in the electrical conduction system, receiving impulses from the sinoatrial (SA) node and delaying them briefly before transmitting them to the ventricles via the bundle of His. This delay allows the atria to fully contract and empty their blood into the ventricles before the ventricles contract.
Where is blood pumped when ventricles contract?
Into the heart
When the ventricles get very full it does what strongly?
contract
When the ventricles contract blood flows from the right ventricles to what?
The right ventricle pumps blood to the lungs.
Do ventricles contract together or does one follow another?
They normally contract together.
