Is gas exchange in the lungs active transport?
Basic Principles of Gas Exchange Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient.

Basic Principles of Gas Exchange Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. The air in the lungs has a higher concentration of oxygen than that of oxygen-depleted blood and a lower concentration of carbon dioxide.Click to see full answer. Likewise, how is gas exchanged in the lungs?Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.Similarly, what type of diffusion is gas exchange? Gas exchange is achieved by diffusion. This is a process by which particles move naturally from a region where they are in high concentration to a region where they are in lower concentration. They move down a concentration gradient: the steeper the gradient, the faster the rate of diffusion. Hereof, how do exchange and transportation of gases occur? Oxygen is passed from the lungs to the bloodstream and carbon dioxide is eliminated from the bloodstream to the lungs. Exchange of Gas takes place in lungs between the alveoli and capillaries which are tiny blood vessels, placed at the walls of alveoli.What is the main function of gas exchange?Gas exchange: The primary function of the lungs involving the transfer of oxygen from inhaled air into the blood and the transfer of carbon dioxide from the blood into the exhaled air.
