Heart Anatomy

Which part of the heart receives deoxygenated blood from both the superior and inferior vena cava, and what are the specific sources of this blood?

• Right Atrium; from the upper body via the superior vena cava and from the lower body via the inferior vena cava

• Left Ventricle; from the upper and lower body

• Left Atrium; from the lungs

• Right Ventricle; from the upper and lower body

Which valve is located between the right ventricle and the pulmonary artery, ensuring that blood is directed from the heart to the lungs for oxygenation?

• Pulmonic Valve

• Aortic Valve

• Mitral Valve

• Tricuspid Valve

Which part of the heart is responsible for pumping oxygen-rich blood into the aorta, and is separated from its counterpart by the interventricular septum?

• Right Atrium

• Right Ventricle

• Left Atrium

• Left Ventricle

Which part of the heart receives oxygenated blood from the pulmonary veins and is separated from the other atrium by the interatrial septum?

• Right Atrium

• Left Atrium

• Right Ventricle

• Left Ventricle

The thin innermost layer of the heart

• Myocardium

• Epicardium

• Endocardium

• Septum

During a biology class, Laura was asked to identify the layer of the heart wall synonymous with the visceral layer of the pericardium. What is it known as?

• myocardium

• endocardium

• epicardium

• parietal layer of the serous pericardium

What describes the Endocardium?

• It is the outermost layer of the heart.

• It is a thick layer of muscle.

• It is a thin layer lining the heart chambers.

• It is responsible for the electrical conduction in the heart.

The muscle layer of the heart is called the:

• endocardium

• myocardium

• pericardium

• epicardium

The thin layer of the heart that is made of connective tissue and fat

• Endocardium

• Epicardium

• Myocardium

• Septum

Which major artery originates from the left ventricle of the heart and is responsible for distributing oxygen-rich blood throughout the body

• Pulmonary Artery

• Coronary Artery

• Carotid Artery

• Aorta
