B. both oxygen and carbon dioxide diffuse from the blood into the alveoli.
C. oxygen diffuses into the blood and carbon dioxide diffuses into the alveoli.
D. carbon dioxide diffuses into the blood and oxygen diffuses into the alveoli.
At the lungs, oxygen diffuses into the blood and carbon dioxide diffuses into the alveoli.
• At the time of exchange of gases, oxygen moves from the lungs to the bloodstream.
• At similar time, carbon dioxide passes into the lungs from the blood.
• This takes place in the lungs between the network of tiny blood vessels known as capillaries and the alveoli.
• The molecules of the oxygen gas combines with the red blood cells that mediates back to the heart.
• The diffusion of carbon dioxide takes place out of the bloodstream, via the capillaries, and into the alveoli from where it is exhaled out.
• At the same time, oxygen combines simultaneously with hemoglobin and is carried back to the tissues.
Thus, the correct answer is option C.
To know more about:
Answer:
C.
Explanation:
It can not be A. because if both oxygen and carbon dioxide diffused from the alveoli into the blood there would be too little oxygen and too much carbon dioxide.
If both oxygen and carbon dioxide diffused into the alveoli like in B. then that is even worse than the first one because that would leave our blood without oxygen that our body needs for functioning.
And D. can't be true because we don't run on CO2 but on O2 and getting rid of O2 for CO2 would kill us.
B Your mind needs to express latent content
C You have narcolepsy
D You learned a lot that day
You did not sleep enough the night before If you have more REM sleep than normal one night.
Rapid eye movement (REM) sleep is a type of sleep that usually starts about 90 minutes after you fall asleep. During this sleep, the brain activity increases, the blood pressure as well as breathing rate also increases. When a person have more REM sleep than normal, it means that You did not sleep enough the night before. This is also occur when you are dreaming. Rapid eye movement (REM) sleep is very important for learning and memory purposes.
Getting an unusually large amount of Rapid eye movement (REM) sleep in a given night indicates that you are sleep deprived. Your body gets most of its Rapid eye movement (REM) sleep later in the night usually during the final hours of our sleep. Rapid eye movement (REM) sleep plays an important role in dreaming, memory, emotions, and healthy brain development of an individual.
So we can conclude that if a person have more Rapid eye movement (REM) sleep than normal one night, it might be because he did not sleep enough the night before.
