|---|---|
| The pointed apex of the heart is oriented toward the: | Left hip |
| Pulmonary circulation involves blood flow to and from the heart and the: | Lungs |
| The right AV valve is known as the: | Tricuspid valve |
| Pulmonary veins: | Transport oxygenated blood to the heart |
| What structure divides the left from the right ventricle: | Interventricular |
| When the ventricles contract, the bicuspid (mitral) valve prevents blood from flowing from the: | Left ventricle to the left atrium |
| The tricuspid valve is located between the: | Right atrium and right ventricle |
| Deoxygenated blood is returned to the right side of the heart by the: | Superior and inferior vena cavae |
| Which one of the following blood vessels carries oxygenated blood: | Pulmonary vein |
| Which valve guards the base of the aorta and opens when the ventricles are contracting: | Aortic semilunar valve |
| Which one of the following represents the correct path for the transmission of an impulse in the intrinsic conduction system of the heart: | Sinoatrial (SA) node, atriovantricular (AV) bundle, atriovantricular (AV) node, right and left bundle branches, Purkinje fibers |
| Matching Atriums and Ventricles | |
| Heart chamber with the thickest wall | Left ventricle |
| Inferior discharging chamber on the left side of the heart | Left ventricle |
| Heart chamber that pumps blood to the pulmonary trunk | Right ventricle |
| Heart chamber that contains the sinoatrial node | Right atrium |
| Roof of this chamber contains the bicuspid valve | Left atrium |
| The four pulmonary veins return oxygenated blood to this chamber | Left atrium |
| This chamber sends blood into the aorta | Left ventricle |
