  • Question:

Why would someone’s pulse increase while smoking a cigarette?


  • Answer: Nicotine causes blood vessels to constrict, therefore raising the blood pressure and resulting in the heart having to pump harder and faster to move the blood through the body.

When valves do not close completely, a harmless sound can occur. This can also occur if there is a hole in the septum of the heart.

  • Question:

Describe how the pumping action of the heart would be affected if it had no valves.


  • Answer: The heart would not be able to move blood in any specific direction. Blood would, therefore, not circulate throughout the body.

Describe how the pumping action of the heart would be affected if it had no valves.


  • Question:

How can you tell that you have a closed circulatory system?


  • Answer: We can see blood vessels under our skin, feel our pulse, and if we cut ourselves we will not bleed out completely. This is suggestive of a closed circulatory system.

How can you tell that you have a closed circulatory system?


  • Question:

Do arteries carry oxygenated blood or deoxygenated blood?


  • Answer: An artery is a blood vessel that carries blood away from the heart. Most arteries carry oxygenated blood from the heart to the rest of the body, but some arteries—the pulmonary arteries, which carry blood from the heart to the lungs—carry deoxygenated blood that has been returned to the heart from the rest of the body.

Do arteries carry oxygenated blood or deoxygenated blood?
