Types Of Cells In The Blood

What are different types of cells in the blood? Blood makes up the greatest proportion of tissues in body. There are numerous ultimate functions of blood cells that exist into the human body. These are necessary for the vitality of each and every cell of the human body and is purposed to carry oxygen to deeper tissues and cell out there. Therefore, for proper functioning of each and every cell of the body, blood must be in effect at the best.

The blood is made up of three types of cells in blood and plasma. Plasma which is the liquid component of blood makes up 55% of blood. It contains water as a major component in it. Many chemicals and drugs in body get dissolved in plasma. So, it is also essential.

Floating in plasma are blood cells which are technically called “hematocytes”. Different types of blood cells can be listed as:

• White blood cells

• Platelets

• Red blood cells

• All these cells collectively make up 45%of the total blood. The highest in proportion are Red Blood cells. Here, I must give you a little detail about these.

Red blood cells (RBCs):

These are in the maximum ratio and make up most of the blood part. They are almost in range of 4-6 million in a microliter of blood. The main function of Red blood cells is to carry oxygen to different cells of body. A red blood has a pigmented protein packed inside it called, hemoglobin. It gives blood its perfect red color. This protein attached oxygen with it when blood passes through lungs.

On the other hand, when red blood cell reaches in vicinity of peripheral tissues like, liver, muscles etc. hemoglobin releases oxygen there and picks up carbon dioxide from cells. This carbon dioxide clearing mechanism of blood is very necessary for vitality of body tissues. Therefore, these minute cells do a perfect job of carbon dioxide and oxygen exchange every moment and never get tired of it.

The average life span of a red blood cell is 120 days. They are formed and replaced after every 3 months by bone marrow.

White blood cells (WBCs):

There are WBCs in blood in quantity of 7,000-11,000 in a microliter of blood. Basically, white blood cells are just like safeguards in our body. They keep a special eye on germs coming from outside of the body.

So, whenever they get sensation of any foreign organism they get aligned and work up to engulf this pathogen which in other case can be seriously harmful for our body. Any deficiency of WBCs as result of a disease results in lowered immunity and makes us more prone to various diseases.

This is one of special types of cells in blood that functions more actively at the place of any infection and clears up bacteria from infected place.


This is one of the types of blood cells that are needed for vitality of blood itself. Platelets are essential for clotting mechanism of blood. They are 0.3-0.5 million in a microliter of blood. If they get lowered in number as a result of any of infection or so they result in serious bleeding. The blood is no more capable of clotting whenever there is any injury. This results in excessive loss of blood that may be disastrous in one way or another.

So, we can conclude that each and every type of cells in blood in very critical to normal functioning of our body. These are some of the major types of cells in the blood.
