The Human Circulatory System Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is double circulation in humans?

A system where blood is pumped through two circuits: pulmonary circulation (heart to lungs) and systemic circulation (heart to body).

What happens during pulmonary circulation?

The right side of the heart pumps deoxygenated blood to the lungs for gas exchange, where oxygen diffuses into the blood and carbon dioxide diffuses out.

What is the main function of systemic circulation?

The left side of the heart pumps oxygenated blood under high pressure to the body, supplying cells with oxygen and nutrients and carrying away carbon dioxide and waste.

Name the four main blood vessels that enter and leave the heart.

Vena cava, pulmonary artery, pulmonary vein, and aorta.

What is the role of coronary arteries?

They supply the heart with oxygen for aerobic respiration, providing energy for contraction.

What does the mnemonic ‘LORD’ help you remember about the heart?

Left Oxygenated, Right Deoxygenated – the left side of the heart pumps oxygenated blood to the body, and the right side pumps deoxygenated blood to the lungs.
