Stimulation of the Purkinje fibers leads to ventricular systole.

Electrical impulses originate in the atrioventricular (AV) node.

​When the left ventricle contracts, the blood is pumped through the aortic valve and into the:

The period of time a chamber is relaxing is called:

The left atrium receives blood returning to the heart after being oxygenated by the lungs. This blood enters the relaxed left atrium from the:

The right ventricle contracts and blood is pumped through the:

​Deoxygenated blood from all the tissues in the body enters a relaxed right atrium via two large veins called:

The Mitral valve is also known as the bicuspid valve because it consists of three cusps, while the Tricuspid valve consists of two.

Both the Tricuspid valve and the Mitral valve have the same number of cusps, as indicated by the prefixes "tri-" and the description of the Mitral valve.

The Aortic valve is responsible for controlling the flow of blood as it leaves the left ventricle.

The Aortic valve allows blood to return to the left ventricle from the aorta.

The Aortic valve is a semilunar valve located between the left ventricle and the aorta.

Located between the right ventricular and the pulmonary artery

The tip of tha heart at the lower edge is called the.........
