External respiration refers to the exchange of oxygen and carbon dioxide between?
Alveoli and bloodstream
Oxygen and carbon dioxide exchange between the circulatory system and tissues occurs at the?
In the lungs - specifically, the alveoli.
Does the exchange of carbon dioxide depend on the concentration of oxygen in the alveoli and the blood?
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
What happens to the oxygen when it reaches the alveoli?
oxygen enters the blood and carbon dioxide
Where does oxygen into the blood and carbon dioxide pass out of the blood?
alveoli
What are the structures that allow for the exchange of oxygen and carbon dioxide between the lungs and blood?
The tiny air sacs of the lungs were oxygen and carbon dioxide are exchanged are the alveoli.
What takes place between the alveoli and capillaries in the lungs?
When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream. During the same process, carbon dioxide is outgassed from the blood to the alveoli When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream.

What fills the alveoli?
Air. Alveoli are air sacs on the end of bronchioli. Gas exchange of carbon dioxide and oxygen occurs through the alveoli.
Why are the alveoli sometimes called respiratory membrane?
The alveoli are sometimes refer to as the respiratory membrane. This due to the transfer of gases that occurs between the epithelium (the membrane) and the capillaries (the blood). When Oxygen and carbon dioxide transfer across this membrane through diffusion Oxygen goes into the blood and Carbon dioxide is diffused out into the Alveoli.
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
What Oxygen and carbon dioxide are exchanged through structures in the lungs called?
Alveoli. this is the right answer
Air sacs in the lungs through which oxygen and carbon dioxide diffuse into and out of the blood are the?
alveoli
What is the process of oxygen flowing through the alveoli's walls?
The answer is diffusion. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale.
Does oxygen passes through the walls of the alveoli from the air into the cappilaries of the whist?
Yes, Oxygen diffuses through the wall of the alveoli then through the walls of the capillaries. :)
External respiration refers to the exchange of oxygen and carbon dioxide between?
Alveoli and bloodstream
What principle causes the exchange of oxygen and carbon dioxide between the capillaries and the alveoli?
diffusion
What passes between alveoli and capillaries?
Capillaries are tiny thin-walled blood vessels that connect the smallest arteries and veins and allow the exchange of nutrients and waste between the blood and tissues. Oxygen and carbon dioxide are exchanged between the circulatory and respiratory systems; oxygen diffuses from the lungs into the bloodstream and is transported by erythrocytes (red blood cells) throughout the body. Carbon dioxide diffuses out of the blood into the alveoli and goes the reverse direction through the respiratory system and out the nose.
