By definition, your blood is a bodily fluid flowing inside and all around your body delivering the necessary nutrients and oxygen to cells in different parts of your body. Blood is also responsible in taking out metabolic waste products that your cells cannot use anymore. Studying your blood is as extensive as any scientific and anatomical topic. The simplest way to understand it is through a series of small topics about its many properties.
One such property that you can study and that can open up a lot of other topics is the color of your blood. Ever since you were a child who had your first bloody wound, you have realized that your blood is actually red. This is a rather common knowledge in your science class as well. But your blood is actually composed of several materials that are different in color like the plasma that is yellow.
So what makes your blood red?
There is a material in your blood that is called hemoglobin. It is a protein that can be found in red blood cells. An oxygen-transport metalloprotein, hemoglobin is tasked mainly with the transport of oxygen from your lungs (your main respiratory organ) to the rest of your body. The oxygen that you inhale is essential for the cells and tissues in your body to burn nutrients from which it would get the energy it needs to function efficiently. Hemoglobin also functions to collect carbon dioxide that is brought back to your lungs for you to expel through exhalation.
Your hemoglobin has a great amount of iron, a substance that enables that transportation of oxygen. Now this iron that has attached oxygen in it is the very reason your blood is red.
Now, as your red blood cells-and the hemoglobin in it-are expected to last for at least four months before they are automatically replaced by your body, you need to make sure that you try to do your best in the gathering of external factors that would boost your body's iron content. There are foods and exercises as well as medications that would help keep your body's iron content high so that it can keep on pushing the hemoglobin around into doing its task of carrying oxygen around the body.
Your blood is definitely important, even if in terms of the simplest attribute like the color. Understanding these attributes can contribute to your understanding of just how essential it is that you keep your blood flow healthy.
