Questions and Answers

What distinguishes heart rate from resting heart rate?

Heart rate is only relevant to athletes; resting heart rate applies to everyone.
Heart rate is measured during rest; resting heart rate is measured during activity.
Heart rate is more variable; resting heart rate remains constant throughout the day.
Heart rate reflects activity levels, while resting heart rate measures baseline heart function. (correct)

What is the expected change in heart rate following anaerobic exercise?

Heart rate decreases immediately after anaerobic exercise.
Heart rate becomes completely variable and unpredictable after anaerobic exercise.
Heart rate may significantly increase during anaerobic exercise and then gradually decrease. (correct)
Heart rate stabilizes and remains unchanged for several minutes.

How does Sickle Cell anemia specifically affect red blood cells?

It increases their lifespan, causing more effective oxygen transport.
It causes a higher number of red blood cells to be produced in response to oxygen deprivation.
It enhances their ability to carry hemoglobin, improving oxygen delivery.
It causes them to become rigid and crescent-shaped, leading to blockages in small blood vessels. (correct)

Flashcards

Heart Rate

The number of times your heart beats per minute. It varies depending on activity level.

Resting Heart Rate

The number of times your heart beats per minute when you are at rest.

Anaerobic Exercise Effect on Heart Rate

Your heart rate increases significantly after anaerobic exercise due to the body's need for oxygen.

Sickle Cell Anemia's Effect on Red Blood Cells

Sickle cell anemia causes red blood cells to become misshapen (crescent-shaped), making it difficult to carry oxygen efficiently.
