Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

During respiration, oxygen is taken into cells and carbon dioxide is give off. What process do these gases move into / out of the cell via?

A	Osmosis
B	Active Transport
C	Diffusion
D	Regulatory Movement

Explanation:

Detailed explanation-1: -This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it. Carbon dioxide (CO2) is a waste product of cellular metabolism.

Detailed explanation-2: -When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.

Detailed explanation-3: -Answer and Explanation: Oxygen and carbon dioxide move through the respiratory membrane and into and out of cells by the process of C: diffusion.

Detailed explanation-4: -Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
