Anatomy And Physiology C1 T1 Flashcards
What moves into the alveoli following inhalation?
Air.
What type of blood vessel is on the outside of the alveoli?
Capillary.
Why is a blood vessel around the alveoli?
Gas exchange.
Where is oxygen transported during gas exchange in the alveoli?
Into the blood by diffusion.
What is a waste product of gas exchange?
Carbon dioxide.
Why is an efficient supply of oxygen required during a rugby game?
Muscles will be respiring more frequently, therefore requiring more oxygen to respire aerobically.
What does the diaphragm and inter coastal muscles do during inhalation.
The diaphragm and inter coastal muscles contracts, therefore causing the diaphragm to pull and flatten and the lungs to pull down.
What happens to the size of the lungs during exhalation?
Reduce in size.
During exhalation, what happens to the concentration of oxygen and why
Decreases because the oxygen is used for aerobic respiration
During exhalation what happens to the concentration of carbon dioxide
Increases as it is a product of respiration
What is breathing rate
The number of breathes taken per minute
What is tidal volume
The The amount of air inhaled in one breath
What is vital capacity
The maximum amount of air that can be exhaled after a maximum inhalation
What is minute ventilation
Amount of air inhaled or exhaled per minute
During gas exchange in the lungs, where is there high concentration of oxygen
The alveoli
