Front

Vein that empties blood from the upper body into the upper right heart chamber

Back

Superior Vena Cava

Front

Arteries taking low oxygenated blood from the lower right heart chamber to the lungs

Back

Pulmonary arteries

Front

The blood enters on the left side of the heart through the ______________ and enters the left atrium. It then passes through the _____________ to enter the left ventricle.

Back

pulmonary vein, bicuspid valve

Front

Pulmonary veins take unoxygenated blood away from the heart

Back

False

Front

On the right side of the heart, blood flows from the right ventricle to the?

Back

Pulmonic valve to the pulmonary artery

Front

What is going on in the heart during the R-wave or QRS complex?

Back

AV node triggers depolarization in the ventricles leading to ventricular contraction.

Front

Last to receive electrical impulses resulting in ventricular systole: AV node, Purkinje fibers, SA node, AV bundle/bundle of His

Back

Purkinje fibers

Front

Place the following in the correct order: 1. atria contract 2. AV node 3. bundle of His/AV bundle 4. Purkinje fibers 5. SA node 6. ventricles contract

Back

5, 1, 2, 3, 4, 6

Front

Influence from the __________ nervous system results in a decrease of the SA node firing rate.

Back

parasympathetic

Front

The AV node is located at...
