Blood is fascinating! While it might be easy to think of it as just a red liquid, it actually plays a critical role in maintaining homeostasis and transporting oxygen, nutrients, and waste. The three formed elements of blood—leukocytes (white blood cells), erythrocytes (red blood cells), and platelets—each have unique functions that keep our bodies running smoothly, from fighting infections to enabling clotting. Now, did you know that the pH level of blood is a delicate balancing act? It’s maintained between 7.35 and 7.45 to ensure that our bodily processes operate efficiently. Deviating from this range can lead to severe health issues, like acidosis or alkalosis, so your body works hard to keep it just right!
