12 Questions
What is the main function of blood in our body?
Carrying nutrients, oxygen, and vitamins to the body
Which component of the circulatory system carries oxygenated blood away from the heart?
Arteries
Why are the walls of arteries thicker and more elastic than veins?
To withstand high blood pressure from the heart
What is located in the space within an artery where blood flows?
Lumen
Why are major arteries located deep inside the body away from the skin's surface?
To carry blood under high pressure without getting damaged
What would happen if a major artery got damaged according to the text?
It could result in extreme rapid blood loss
Match the following components of the circulatory system with their descriptions:
Arteries = Carries oxygenated (pure blood) away from the heart to the rest of the body Veins = Carries deoxygenated (impure blood) back to the heart Capillaries = Tiny blood vessels where oxygen and nutrients are exchanged with body tissues Aorta = The main artery that carries oxygenated blood from the heart
Match the following terms with their functions in the circulatory system:
Blood = Carries nutrients, oxygen, and vitamins to the body Blood vessels = Transport blood throughout the body Heart = Pumps blood to all parts of the body Lumen = Space within an artery where blood flows
Match the following characteristics with either arteries or veins:
Thicker and more elastic walls = Arteries Carries blood under high pressure = Arteries Carries blood back to the heart = Veins Located deep inside the body = Arteries
Match the following statements with either arteries or veins:
Have a sleek inner layer (lumen) = Arteries Carry blood at a lower pressure = Veins Located closer to the surface of the skin = Veins Can expand to accommodate more blood = Veins
Match the following facts about arteries with their descriptions:
3 layers - outer, muscle, inner = Arteries Smaller lumen to maintain high pressure = Arteries Damage can lead to rapid blood loss = Major arteries Flow blood at a high pressure = Arteries
Match the following functions with their roles in the circulatory system:
Regulates body temperature = Blood Transport nutrients and oxygen to tissues = Blood vessels Pumps blood throughout the body = Heart Exchange of substances between blood and tissues = Capillaries
Learn about the circulatory system, which is responsible for circulating blood throughout the body to deliver nutrients and oxygen. Explore the functions of blood, blood vessels, and the heart, including their roles in regulating body temperature and maintaining overall health.
