The Respiratory System Flashcards
What kind of gas exchange takes place in the alveoli?
Oxygen passes through the alveoli sacks and into the bloodstream, CO2 from the blood comes out into the lungs and we breath out the Carbon Dioxide.
The oxygen goes into the bloodstream and allows our muscles to work effectively and efficiently. This is why having a larger VO2 max is beneficial for athletes as it allows them to run for longer without becoming fatigued and tired, improving their overall fitness.
Name the main parts of the respiratory system.
Trachea Bronchi Bronchioles Alveoli Oesophagus Diaphragm Ribs Intercostal Muscle Larynx
What is the oesophagus?
It is your throat where you take in air through inspiration along with oxygen and where air will be exhaled through exhalation.
What is the function of the diaphragm?
It is a large muscle below the ribs that pushes air up through the body and can be made stronger through exercise but particularly aerobic and anaerobic respiration.
What takes place at the alveoli?
Gas exchange where carbon dioxide in the blood comes into the lungs and the oxygen diffuses into the blood to go around and deliver oxygen to working muscles. We then breathe out the waste carbon dioxide through exhalation.
What is Oxygen Debt?
The amount of oxygen required at the end of physical activity to break down any lactic acid.
What is V02 Max?
It is the max volume of oxygen that we can consume whilst exercising at maximum capacity.
Define Aerobic Respiration.
When the body releases energy from glucose using oxygen.
Define Anaerobic Respiration. When the body releases energy from glucose without using oxygen.
When the body releases energy from glucose without using oxygen.
How are the Alveoli adapted to undergo gas exchange?
They have many lines of tiny capillaries that run over them carrying oxygenated blood to these areas. This allow them to get their refill of oxygen even faster and then they can continue diffusing it into the blood and getting the waste C02 out of the body.
