Exercise and Asthma Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

Why do muscles need more oxygen and glucose during exercise?

Muscles need more oxygen and glucose during exercise to produce energy through cellular respiration. Without them, muscles become fatigued and cannot sustain physical activity.

How does the respiratory system respond to increased physical activity?

The respiratory system increases the rate and depth of breathing to bring more oxygen into the body to meet the muscles’ energy needs.

What benefits can regular exercise have on the respiratory system?

Regular exercise can improve respiratory muscle strength and endurance, increase the number and size of small blood vessels in the lungs, and increase the number of functional alveoli, making gas exchange more efficient.

What is asthma?

Asthma is a condition where the airways become narrow, swollen, and blocked by excess mucus, making breathing difficult.

What are common symptoms of asthma?

Common symptoms of asthma include shortness of breath, wheezing, and a tight chest.

How is asthma usually managed?

Asthma is often managed with medications delivered through an inhaler, which provides a precise dose of medication directly to the airways to control symptoms and prevent attacks.
