The Tiny Cells That Keep You Alive: All About Red Blood Cells

5 min read

Whenever we get hurt while jumping, or doing mischief, knowingly or unknowingly, we scream when we see blood. They keep adopting different methods to ensure that there is no serious injury and there is no excess blood left. But why do we do this? Why is this blood so important? Do you know and do you know why the blood of us humans is red in color? Could this be because red is the favorite color of most people? No, not at all. No such reasoning works in science.

Then why is blood red in color? The answer is red blood cells, due to which the color of blood is red. So where did these red blood cells come from and what is their purpose? To know the answer to this, we need to know a little about blood and that blood is necessary for our survival because it delivers oxygen and nutrients to every part of the body, and due to this, all the body parts can do their work properly Use to do it. This blood itself carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system, from where they are expelled out of the body. Blood does not get tired even after doing all this. That is why it is responsible for fighting infections and carrying hormones in the body.

So, we are talking about blood and this blood is made up of blood cells and plasma there are three types of blood cells i.e. red blood cells, white blood cells, and platelets. And today we have to know about the cells that give red color to blood i.e. red blood cells RBC. So let us talk further about red blood cells. Red blood cells are also called recovery sites. This is the most common blood cell type and covers forty to five percent of the blood volume. There are 20 to 30 trillion red blood cells present in an adult human body. An average adult human produces 2 to 3 million red blood cells every second and about 200 billion RBCs are produced every day.

Their diameter is approximately six micrometers, which makes them larger than platelets and smaller than white blood cells. These red blood cells develop in the soft bone tissue of the human body, the bone marrow, and after becoming completely mature, they join the blood. This process takes about seven days and the process of RBC formation is called retrograde Human red blood cells are small round and concave on both sides. In many diseases, the shape of red blood cells changes, such as in anemia they become oval-shaped. In sickle cell anemia, it becomes crescent-shaped, which looks like a crescent moon. It does not have a nucleus. That is why it is so flexible that it can pass through even very small blood vessels and due to the absence of a nucleus, RBC has more space for hemoglobin, which makes it easier to carry more oxygen molecules.

This is the delivery mechanism that delivers oxygen from the lungs to the body’s tissues. Tissues produce energy from this oxygen and release waste carbon dioxide. RBCs also do the work of carrying this carbon dioxide to the lungs, so that we can sell it. So overall RBC works amazing. Okay, but how do they get red color? So the bright red color of red blood cells is due to the hemoglobin protein and due to this protein, it becomes possible for RBCs to bring oxygen from the lungs and deliver it to the tissues. Because hemoglobin contains a red-colored compound, which is called snow. This snow is necessary to carry oxygen in the bloodstream. now also contains an iron atom, which binds with oxygen, and hence red blood cells are able to transport oxygen from the lungs to other body parts.

What a systematic mechanism it is, isn’t it? You can also understand it in one line in this way that hemoglobin, a red iron-rich protein, is found in red blood cells, which bind oxygen. So the life of RBC which fulfills so many duties is short. This means that human RBCs can survive only for 120 days and when they become old and damaged, they are thrown out of the bloodstream. This work is done by the spleen and liver. Of these, the spleen eliminates old and damaged RBCs and maintains balance in the amount of RBCs in the body. So the liver recycles iron from all these damaged RBCs. Amazing teamwork isn’t it? But whenever there is a deficiency of nutrients like iron in the body, the quantity of RBC becomes low and this condition is called anemia. In this, symptoms like fatigue, loss of appetite, difficulty in breathing, rapid heartbeat, and yellowness of the skin start appearing.

In the case of anemia, the body has to work harder to deliver oxygen to the cells. This situation can be normalized with a healthy diet and such a diet should be rich in iron, vitamin B, vitamin B, vitamin C, copper, and vitamin A along with a healthy diet, healthy changes in lifestyle are also necessary, about which doctors Should be consulted. Similarly, red blood cell count in the blood can also be high and this condition is called policy fame. Reasons for this include smoking, taking anabolic steroids, being dehydrated, and having heart-lung disease. Conditions in the Old Person may include fatigue, difficulty in breathing, joint pain, itching on the skin after bathing, and sleep disturbance. To avoid this condition, exercise should be done to normalize the high RBC count Iron rich foods and iron supplements should be consumed less. One should stay hydrated and stay away from smoking. The test to check RBC count is CBC i.e. Complete Blood Count test, through which the count of blood cells is determined.

On the same issue, if we talk about normal blood cell count in males and females, then in males, there are four point seven to six point one million red blood cells present in a microliter of blood. Of these, Piper four million RBCs and children and microliter four points zero to five point 22 million red blood cells are present and if the RBC count goes out of this range then it is either low or high, which is called balance. Further tests and treatments are done to do this. By the way, you should also know that the red blood cell count is very high at the time of birth, which decreases immediately after birth and gradually comes to the adult level at a young age. You should also know that anemia, thalassemia policy, them or bone marrow disease, and hypoxia are RBC-related diseases. So, friends, the discussion started in this way while finding out the red color of blood, We reached RBC and then we came to know that the short life of RBC is very busy and it plays a big role in the proper functioning of our body. Is. By the way, how did you feel after knowing this information and the contribution of RBC to our body?
