Trace a Drop of Blood through the Heart Practice

Front

What type of blood returns to the heart from the brain?

Back

CO2 (carbon dioxide-rich blood)

Front

What is the correct order of blood flow from the left ventricle?

Back

Left ventricle → Aortic semilunar valve → Aorta

Front

What is the next structure in the sequence: Superior vena cava, right atrium, right atrioventricular valve, ___?

Back

Right ventricle

Front

What structure follows the right ventricle in the blood flow sequence?

Back

Pulmonary semilunar valve

Front

Which major blood vessel carries blood entering the heart from the brain?

Back

Superior vena cava

Front

What is the function of the aortic semilunar valve?

Back

To prevent backflow of blood from the aorta into the left ventricle.

Front

What is the role of the pulmonary semilunar valve?

Back

To prevent backflow of blood from the pulmonary artery into the right ventricle.

Front

What is the pathway of blood flow starting from the right ventricle?

Back

Right ventricle → Pulmonary semilunar valve → Pulmonary artery → Lungs.

Front

What is the significance of the superior vena cava?

Back

It carries deoxygenated blood from the upper body to the right atrium.

Front

What is the role of the right atrioventricular valve?

Back

To allow blood to flow from the right atrium to the right ventricle while preventing backflow.
