Exercise Physiology - Short term effect - Respiratory

Question 3

What is the primary function of the respiratory system?

Answer 3

To facilitate gas exchange, supplying oxygen to the body and removing carbon dioxide.

Question 4

True or False: The respiratory rate increases during exercise.

Answer 4

True

Question 5

Fill in the blank: During exercise, the volume of air inhaled and exhaled per breath is known as _____ volume.

Answer 5

tidal

Question 6

What happens to tidal volume during intense exercise?

Answer 6

Tidal volume increases.

Question 7

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

Answer 7

B) Increased breathing rate

Question 8

How does exercise affect the efficiency of gas exchange in the lungs?

Answer 8

Exercise increases the efficiency of gas exchange due to increased blood flow and ventilation.

Question 9

True or False: The respiratory system does not adapt during short-term exercise.

Answer 9

False

Question 10

What is the term for the maximum volume of air that can be exhaled after a maximum inhalation?

Answer 10

Vital capacity

Question 11

Fill in the blank: The increase in respiratory rate during exercise is primarily due to higher levels of _____ in the blood.

Answer 11

carbon dioxide

Question 12

What role does the diaphragm play during exercise?

Answer 12

The diaphragm contracts to increase lung volume and facilitate inhalation.

Question 13

Multiple Choice: Which gas is primarily increased in the blood during exercise? A) Oxygen B) Nitrogen C) Carbon Dioxide

Answer 13

C) Carbon Dioxide

Question 14

How does exercise impact the oxygen uptake in the body?

Answer 14

Oxygen uptake increases to meet the higher energy demands of the body.

Question 15

True or False: The respiratory system can become fatigued during prolonged exercise.

Answer 15

True

Question 16

What is the term for the total volume of air that can be inhaled and exhaled in one breath cycle?

Answer 16

Tidal volume

Question 17

Fill in the blank: The _____ reflex helps to regulate breathing during exercise.

Answer 17

stretch

Question 18

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

Answer 18

B) Decreased lung capacity

Question 19

What happens to the respiratory muscles during exercise?

Answer 19

They become more active and stronger.

Question 20

True or False: Breathing becomes deeper but slower during intense exercise.

Answer 20

False

Question 21

What is the physiological response that helps to increase oxygen delivery to muscles during exercise?

Answer 21

Increased heart rate and respiratory rate.

Question 22

Fill in the blank: The process of _____ is the exchange of gases between the lungs and the bloodstream.

Answer 22

diffusion

Question 23

Multiple Choice: Which of the following factors increases during exercise? A) Oxygen debt B) Oxygen consumption C) Oxygen saturation

Answer 23

B) Oxygen consumption

Question 24

What adaptation occurs in the respiratory system with regular exercise over time?

Answer 24

Increased lung capacity and improved efficiency of gas exchange.

Question 25

True or False: Short-term effects of exercise on the respiratory system are permanent.

Answer 25

False

Question 26

What is the role of chemoreceptors during exercise?

Answer 26

They detect changes in blood ph and stimulate increased breathing rates.

Question 27

Fill in the blank: The _____ center in the brain regulates the rate and depth of breathing.

Answer 27

respiratory control centre
