If the carbon dioxide level in the blood is 46mm Hg and the carbon dioxide level in the alveoli is 40 mm Hg
If the carbon dioxide level in the blood is 46mm Hg and the carbon dioxide level in the alveoli is 40 mm Hg, then carbon dioxide moves by
simple diffusion from the alveoli into the blood
simple diffusion from the blood into the alveoli
active transport from the alveoll into the blood
by active transport from the blood into the alveoli
Homework Answers
Simple diffusion from blood to alveoli.
The respiratory gases uses supple diffusion mechanism to transfer between the tissues. CO2 like other gases moves from a region of high partial pressure to low partial pressure region. The partial pressure of CO2 in blood is more than that of alveoli. So CO2 diffuses from blood to the alveoli.

During respiratory exchange, carbon dioxide moves from the blood into the alveoli due to: the presence of a permease , which removes carbon dioxide from the capillaries. the contraction of the diaphragm, which creates a vacuum that pulls it out. diffusion down a concentration gradient. the air pressure of dissolved oxygen, which forces it out. two of the choices are correct

Which of the following explains why the PO2 of the blood leaving pulmonary capillaries is 104 mm Hg, but the blood leaving the lungs to enter the left atrium is 95 mm Hg? Some oxygen diffuses out of the blood as it travels through the pulmonary veins. Some carbon dioxide in the alveoli is mixed with oxygenated blood from alveolar circulation. Some carbon dioxide in the alveoli is mixed with oxygenated blood from alveolar circulation. Some oxygen is incorporated into...
