deoxygenated blood is the same as oxygen poor blood is the same as blood that is low in oxygen saturation


The human body needs a steady supply of nutrients and gases to survive and thrive. To keep our bodies functioning properly, we all have to regularly breathe in oxygen and consume good nutrition. Thankfully, we have a few “difficult to ignore” natural signals that clearly indicate to us when we need to eat (hunger), breathe (the pain of suffocation), or drink (thirst). Without these signals, the human race would have probably gone extinct ages ago. Can you imagine a world in which none of us ever felt any hunger?

When you eat for instance, the food ends up in your stomach and gets digested there for the most part, but the resulting nutrients from your digested food must somehow be distributed to the rest of your body.
