Circulatory System Flashcards

Front

What is the Pulmonary Circulation Loop?

Back

Moves deoxygenated blood from the heart to the lungs to release CO₂ and pick up O₂, then returns it to the heart.

Front

What is the Systemic Circulation Loop?

Back

Distributes oxygen-rich blood from the heart to the rest of the body and returns oxygen-poor blood back to the heart.

Front

What is the pathway of deoxygenated blood?

Back

Vena cava → Right atrium → Tricuspid valve → Right ventricle → Pulmonary valve → Pulmonary artery → Lungs

Front

What is the pathway of oxygenated blood?

Back

Pulmonary veins → Left atrium → Mitral valve → Left ventricle → Aortic valve → Aorta → Body

Front

What do the venae cavae do?

Back

The superior vena cava brings blood from the upper body; the inferior vena cava brings blood from the lower body to the right atrium.

Front

What do pulmonary arteries carry?

Back

Deoxygenated blood from the right ventricle to the lungs.

Front

What do pulmonary veins do?

Back

Return oxygenated blood from the lungs to the left atrium.

Front

What is the aorta?

Back

Largest artery in the body; distributes oxygenated blood from the heart to the rest of the body.

Front

What is coronary circulation?

Back

Part of the systemic loop; supplies blood to the heart muscle itself.

Front

What are capillaries (systemic)?

Back

Where oxygen is delivered to tissues and carbon dioxide is collected from cells.
