Heart Anatomy and Function Assessment

The video provides an overview of heart anatomy and physiology, focusing on its function as a pump. It explains the heart's chambers, blood flow, and the role of coronary arteries in supplying blood to the heart. The electrical system, including the sinoatrial node and ventricular contraction, is also covered. Additional resources are available for further learning.

What is the primary function of the heart?

• To produce hormones

• To filter waste from the blood

• To pump blood throughout the body

• To digest food

Which chamber of the heart receives blood from the superior and inferior vena cava?

• Right ventricle

• Left ventricle

• Right atrium

• Left atrium

Through which valve does blood flow from the right atrium to the right ventricle?

• Pulmonary valve

• Mitral valve

• Aortic valve

• Tricuspid valve

What is the role of the coronary arteries?

• To supply blood to the heart muscle

• To carry oxygenated blood to the lungs

• To remove waste from the body

• To regulate heart rate

Which artery supplies the left ventricle and septum?

• Right coronary artery

• Left anterior descending artery

• Circumflex artery

• Pulmonary artery

What is the function of the sinoatrial node?

• To contract the ventricles

• To slow down the heart rate

• To act as the heart's pacemaker

• To supply blood to the heart

What is the purpose of the atrioventricular node?

• To speed up electrical signals

• To delay electrical signals

• To contract the atria

• To supply blood to the ventricles

Which structure carries electrical signals from the atrioventricular node to the septum?

• Sinoatrial node

• Left bundle branch

• Bundle of His

• Purkinje fibers

What is the role of the Purkinje fibers?

• To initiate the heartbeat

• To delay the electrical signal

• To carry the electrical signal to the heart muscle

• To supply blood to the heart
