Gas Exchange Flashcards
What is gas exchange?
Gas exchange is the process by which oxygen is taken in and carbon dioxide is expelled from the body.
Where does gas exchange primarily occur in the human body?
Gas exchange primarily occurs in the alveoli of the lungs.
Which gas is taken in during the process of gas exchange?
Oxygen is taken in during the process of gas exchange.
Which gas is expelled from the body during gas exchange?
Carbon dioxide is expelled from the body during gas exchange.
What is the role of red blood cells in gas exchange?
Red blood cells transport oxygen to the body’s tissues and carry carbon dioxide away from the tissues to be expelled.
What is the function of the alveoli in gas exchange?
The alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to leave the bloodstream.
How does gas exchange happen at the alveoli?
Gas exchange at the alveoli occurs through diffusion, where oxygen moves from the air into the bloodstream and carbon dioxide moves from the bloodstream into the air.
How does the body ensure efficient gas exchange?
The body ensures efficient gas exchange by maintaining a concentration gradient for oxygen and carbon dioxide between the alveoli and the blood.
What happens to the carbon dioxide that is expelled during gas exchange?
The carbon dioxide that is expelled during gas exchange is carried by red blood cells back to the lungs to be exhaled.
What factors can affect the efficiency of gas exchange?
Factors such as lung diseases, altitude, exercise, and smoking can affect the efficiency of gas exchange.
What is the role of the diaphragm in gas exchange?
The diaphragm is a muscle that contracts and relaxes to create changes in lung volume, allowing for inhalation and exhalation during gas exchange.
What is the term for the process of gas exchange in plants?
The term for the process of gas exchange in plants is photosynthesis.
What gas do plants take in during the process of gas exchange?
Plants take in carbon dioxide during the process of gas exchange.
What gas do plants release during the process of gas exchange?
Plants release oxygen during the process of gas exchange.
Where does gas exchange primarily occur in plants?
Gas exchange primarily occurs in the stomata of plant leaves.
