1.2.4 Effects of Exercise on Breathing

• What is the process of respiration?

  Releasing energy from food
• Anaerobic respiration releases more energy than aerobic respiration

  False
• What is the definition of tidal volume?

  Air breathed in and out
• What is the vital capacity in the respiratory system?

  Maximum air volume
• Match the respiratory system component with its function:

  Nose and nasal cavity ↔️ Warm, moisten, and filter air

  Trachea ↔️ Carries air to lungs

  Bronchi and bronchioles ↔️ Branch into lungs

  Alveoli ↔️ Gas exchange
• Breathing rate is measured in beats per minute (BPM).


  True
• How does physical activity affect the breathing rate?

  Breathing rate increases
• Vital capacity changes during exercise to meet oxygen demands.

  False
• What is the waste product of anaerobic respiration?

  Lactic acid
• Gas exchange in the lungs occurs in the alveoli
• During exercise, breathing rate increases to bring in more oxygen and remove more carbon dioxide
• Infants have higher breathing rates that decrease with age
• Respiratory diseases can significantly increase or decrease breathing rate
• Oxygen uptake during exercise increases to meet the body's higher energy demands
• What waste product is produced during anaerobic respiration?

  Lactic acid
• Gas exchange in the lungs occurs in the alveoli
• During exercise, the respiratory system removes excess carbon dioxide
• Why does the tidal volume increase during exercise?

  Allows more air exchange
• Steps in the respiratory system during exercise:

  1️⃣ Increase in oxygen demand

  2️⃣ Increase in carbon dioxide production

  3️⃣ Increased breathing rate

  4️⃣ Increased tidal volume
• Fit individuals typically have lower resting breathing rates
• What happens to tidal volume during exercise?

  Tidal volume increases
• Steps in aerobic respiration:

  1️⃣ Glucose is broken down

  2️⃣ Oxygen is used

  3️⃣ Large amount of energy released
• The bronchi and bronchioles branch throughout the lungs
• Vital capacity is the maximum volume of air that can be inhaled or exhaled
• Breathing rate is measured in beats per minute (BPM).


  True
• Breathing rate increases during exercise.


  True
• Vital capacity remains unchanged during exercise.


  True
• The respiratory system adapts during exercise to meet higher oxygen requirements and remove excess carbon dioxide.


  True
• Aerobic respiration uses oxygen to release energy from food
• Steps of air movement through the respiratory system

  1️⃣ Nose and nasal cavity

  2️⃣ Trachea

  3️⃣ Bronchi and bronchioles

  4️⃣ Alveoli
• Vital capacity is the volume of air breathed in and out during normal breathing

  False
• During exercise, the breathing rate increases
• Respiratory changes during exercise meet higher oxygen requirements and remove excess carbon dioxide
• What happens to the breathing rate of infants compared to adults?

  Infants have higher rates
• Match the respiratory measure with its definition:

  Tidal Volume ↔️ Air volume breathed in and out

  Vital Capacity ↔️ Maximum air volume inhaled or exhaled
• Oxygen uptake increases during exercise to meet higher energy demands
• The tidal volume is the volume of air breathed in and out during normal breathing
• Tidal volume is the volume of air breathed in and out during normal breathing.

  True
• During exercise, tidal volume increases to allow more air to be inhaled and exhaled
• Fit individuals typically have lower resting breathing rates
