Exploring the Circulatory System Through Rap

The video follows a red blood cell's journey through the circulatory system, starting at the inferior vena cava. It travels to the right atrium, then to the right ventricle, and heads to the lungs for oxygenation. The oxygenated blood returns to the heart via the left atrium and is pumped through the aorta to the rest of the body. The process repeats as the blood delivers oxygen and collects carbon dioxide, emphasizing the roles of different heart chambers and valves.

Where does the journey of the red blood cell start?

• Pulmonary artery

• Inferior vena cava

• Left ventricle

• Right atrium

What is the name of the valve between the right atrium and right ventricle?

• Pulmonary valve

• Aortic valve

• Tricuspid valve

• Bicuspid valve

Which chamber of the heart does the blood enter after being oxygenated in the lungs?

• Left ventricle

• Right ventricle

• Left atrium

• Right atrium

Through which valve does the blood pass from the left atrium to the left ventricle?

• Aortic valve
