Blood Flow Basics - Video Notes (Q&A)

Question-and-answer flashcards focusing on the core concepts of blood flow through the heart and circulation, inspired by the video notes.

What is the basic sequence of blood flow through the heart starting from the right atrium?

Right atrium → right ventricle → pulmonary artery → lungs → pulmonary veins → left atrium → left ventricle → aorta.

Which valve separates the right atrium and right ventricle?

Tricuspid valve.

Which chamber pumps oxygenated blood into the systemic circulation?

Left ventricle.

What vessel carries blood from the left ventricle to the body?

Aorta.

Which circuit carries blood to the body and back to the heart?

Systemic circulation.

What valves prevent backflow and ensure unidirectional blood flow through the heart?

The four valves: tricuspid, mitral (atrioventricular), and the pulmonary and aortic semilunar valves.
