What is the name of the muscle that pumps blood out of the ventricles?
the heart
What is the name of the wall in the center of the heart?
The septum; it's a muscle that seperates your right and left ventricles.
What differences between the atria and the ventricles?
-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
Which layer of the stomach is muscle arranged in folds?
Mucosa
What is the birth name of Ben Folds?
Ben Folds's birth name is Benjamin Scott Folds.
The qrs complex corresponds to depolarization of the muscle fibers of the?
the ventricles.
The T wave corresponds to the repolarization of the muscle fibers of the?
Ventricles
Does the cardiac muscle open and close?
some does like the atriums and the ventricles
What are the electrical impulses in the heart that are relayed to the ventricles by what?
A junction box, also known as the AV node, is how electrical impulses in the heart are relayed to the ventricles. The ventricles help make the muscle contract and then pump the blood.
The T wave in a electrocardiogram results from?
Repolarization of ventricular muscle fibers.
Why does the QRS complex have the largest amplitude?
More cells depolarize during this QRS complex(ventricular contraction). The reason is because the muscle mass of the atria is small compared with that of the ventricles. The ventricles have a larger muscle mass. Therfore the electrical impulses within the atria are shorter and are less. The ventricles are larger so there is a larger deflection of the ECG when the ventricles are depolarised this is called the QRS complex
When does the human heart rest?
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.
