Question

Process responsible for movement of oxygen from the alveoli into blood in the pulmonary capillaries is


Facilitated diffusion


Simple diffusion


Active transport


Filtration

Answer 1

process responsible for movement of oxygen from the alveoli into blood in pulmonary capillaries is "FILTRATION"

Answer 2

Process responsible for movement of oxygen from the alveoli into blood in the pulmonary capillaries is Simple diffusion.

Explanation:

1. Alveoli are situated in direct contact with capillaries (one-cell thick) of the circulatory system.
2. Diffusion is known for oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls. When the bloodstream, oxygen gets picked up by hemoglobin in red blood cells.
3. Oxygen(O) and carbon dioxide (CO2) move across cell membranes via simple diffusion. A process in which requires no energy input and is travels differences in concentration on either side of the cell membrane.

Hence,

option (2) Simple Diffusion is correct answer.
