As we breathe, we take oxygen into our lungs and push carbon dioxide out. Let's take a moment to consider the physiological significance of these gases before we dive into how carbon dioxide is transported in our body.
Our cells need oxygen to make ATP, and ATP is needed for cellular work. Carbon dioxide is a product of this cellular metabolism. Carbon dioxide is a waste product and must be removed from our body, much like trash must be taken out of the house. While carbon dioxide is metabolic trash, it seems our bodies have found a use for carbon dioxide as it is transported from our tissues to the lungs. In this lesson, we will discuss both the means by which carbon dioxide is transported and how carbon dioxide helps with pH balance and oxygen transport.
