Circulatory System Learning Checkpoint

What is the difference between pulmunary circulation and systematic circulatioon?

• Pulmonary circulation involves the heart, while systemic circulation involves the lungs.
• Pulmonary circulation involves the lungs, while systemic circulation involves the rest of the body.
• Pulmonary circulation involves the brain, while systemic circulation involves the liver.
• Pulmonary circulation involves the kidneys, while systemic circulation involves the stomach.

How do arteries and veins differ in structure and function?

• Arteries have thinner walls and carry blood to the heart, while veins have thicker walls and carry blood away from the heart.

• Arteries have thicker walls and carry blood away from the heart, while veins have thinner walls and carry blood to the heart.

• Both arteries and veins have similar structures but differ only in the direction they carry blood.

• • Arteries and veins both carry oxygenated blood, but veins have valves to prevent backflow.

What would most likely happen if the valves in the heart did not function properly?

• The heart would stop beating entirely, resulting in immediate death.

• Blood would flow too quickly through the heart, causing high blood pressure.

• Blood would flow backward in the heart, leading to inefficient circulation and potential organ damage.

• The heart would pump blood more efficiently, improving overall circulation.

Differentiate oxygentaed blood from deoxygenated blood.

• Oxygenated blood carries oxygen, while deoxygenated blood carries carbon dioxide.

• Oxygenated blood carries carbon dioxide, while deoxygenated blood carries oxygen.

• They both carry oxygen, but oxygenated blood travels in veins.

• They both carry carbon dioxide, but oxygenated blood travels in arteries.

What is the best way to demonstrate the effects of exercise on heart rate?

• Compare the heart rate of two different people, one who exercises and one who does not.

• Measure your own heart rate before and after running in place for 5 minutes.

• Observe how fast your heart beats when you are nervous.

• Ask your friends how they feel after they exercise.
