Exercise Physiology - Short term effect - Respiratory COPY Flashcards
What is the primary function of the respiratory system?
To facilitate gas exchange, supplying oxygen to the body and removing carbon dioxide.
True or False: The respiratory rate increases during exercise.
True
Fill in the blank: During exercise, the volume of air inhaled and exhaled per breath is known as _____ volume.
tidal
What happens to tidal volume during intense exercise?
Tidal volume increases.
Multiple Choice: Which of the following is a short-term effect of exercise on the respiratory system? A) Decreased oxygen uptake B) Increased breathing rate C) Decreased lung capacity
B) Increased breathing rate
How does exercise affect the efficiency of gas exchange in the lungs?
Exercise increases the efficiency of gas exchange due to increased blood flow and ventilation.
True or False: The respiratory system does not adapt during short-term exercise.
False
What is the term for the maximum volume of air that can be exhaled after a maximum inhalation?
Vital capacity
Fill in the blank: The increase in respiratory rate during exercise is primarily due to higher levels of _____ in the blood.
carbon dioxide
What role does the diaphragm play during exercise?
The diaphragm contracts to increase lung volume and facilitate inhalation.
Multiple Choice: Which gas is primarily increased in the blood during exercise? A) Oxygen B) Nitrogen C) Carbon Dioxide
C) Carbon Dioxide
How does exercise impact the oxygen uptake in the body?
Oxygen uptake increases to meet the higher energy demands of the body.
True or False: The respiratory system can become fatigued during prolonged exercise.
True
What is the term for the total volume of air that can be inhaled and exhaled in one breath cycle?
Tidal volume
Fill in the blank: The _____ reflex helps to regulate breathing during exercise.
stretch
Multiple Choice: Which of the following is NOT a short-term effect of exercise on the respiratory system? A) Increased respiratory rate B) Decreased lung capacity C) Increased tidal volume
B) Decreased lung capacity
What happens to the respiratory muscles during exercise?
They become more active and stronger.
True or False: Breathing becomes deeper but slower during intense exercise.
False
What is the physiological response that helps to increase oxygen delivery to muscles during exercise?
Increased heart rate and respiratory rate.
Fill in the blank: The process of _____ is the exchange of gases between the lungs and the bloodstream.
diffusion
Multiple Choice: Which of the following factors increases during exercise? A) Oxygen debt B) Oxygen consumption C) Oxygen saturation
B) Oxygen consumption
What adaptation occurs in the respiratory system with regular exercise over time?
Increased lung capacity and improved efficiency of gas exchange.
True or False: Short-term effects of exercise on the respiratory system are permanent.
False
What is the role of chemoreceptors during exercise?
They detect changes in blood ph and stimulate increased breathing rates.
Fill in the blank: The _____ center in the brain regulates the rate and depth of breathing.
respiratory control centre
