Question

The movement of oxygen from the alveoli into pulmonary capillaries and carbon dioxide from pulmonary capillaries to the alveoli is: Select one: a. Internal Respiration b. External Respiration c. Pulmonary Respiration d. None of the above.

Answer 1

External Respiration.

Step-by-step explanation:

External Respiration is the type of respiration in which exchanges of gases occurs between the lungs and the bloodstream i.e. pulmonary capillaries. Inside the lungs, oxygen is loaded into the hemoglobin and carbon dioxide waste is unloaded, this process is called external respiration. This respiratory process takes place through the help of hundreds of millions of microscopic alveoli.
