Circulatory System Flashcard

Front

What are capillaries?

Back

Capillaries are very tiny blood vessels that connect arteries and veins, allowing for the exchange of oxygen, carbon dioxide, nutrients, and waste between blood and tissues.

Front

What are alveoli?

Back

Alveoli are the air sacs in the lungs responsible for the exchange of oxygen and carbon dioxide during breathing.

Front

What does deoxygenated mean?

Back

Deoxygenated refers to blood that is oxygen-poor, meaning it has a low concentration of oxygen.

Front

Where do the oxygen and nutrients get picked up by the blood?

Back

The lungs are where the oxygen and nutrients are picked up by the blood.

Front

Which of the following is NOT a chamber of the heart?

Back

The aorta is NOT one of the chambers of the heart; it is a major artery.

Front

What is the function of arteries?

Back

Arteries carry oxygen-rich blood away from the heart to the body's tissues.

Front

What is the role of veins in the circulatory system?

Back

Veins carry deoxygenated blood back to the heart from the body's tissues.

Front

What is the heart's primary function?

Back

The heart's primary function is to pump blood throughout the body, supplying oxygen and nutrients while removing waste products.

Front

What is the significance of the aorta?

Back

The aorta is the largest artery in the body, responsible for distributing oxygen-rich blood from the heart to the rest of the body.

Front

What is the difference between oxygenated and deoxygenated blood?

Back

Oxygenated blood is rich in oxygen and is carried from the lungs to the heart, while deoxygenated blood is low in oxygen and is carried from the body back to the heart.
