What is blood plasma?

It is the yellowish liquid component of the blood that holds the blood cells. Blood plasma is the liquid part of the blood that transfers cells and proteins throughout the whole body.

Plasma makes fifty-five percent of the blood.

It is the part of extracellular fluid (fluid which is present outside the cells).

It mainly consists of water and dissolved proteins. The main functions of the plasma are that they play a role in the intravascular osmotic effect and also protect the body from infections and blood disorders.

What is the composition of plasma?

Plasma mainly contains water, dissolved proteins, glucose, clotting factors, and electrolytes.

Water makes 95% of plasma by volume.

Proteins present in the plasma are serum albumin, globulins, and fibrinogens.

Electrolytes which are present in the plasma are sodium, potassium, chloride, and calcium.


Volume of plasma

Plasma volumes change from time to time depending on the condition of the body.

For example
In the low blood pressure, the fluid goes into the interstitium.


Plasma and health

Human plasma contains water, salts, enzymes, immunoglobulins, clotting factors, albumin, and fibrinogen. When volunteers donate their blood health professionals isolate various content of it and make new products.

These products are then used in various conditions such’s as burn, shocks and many others.

The components present in the plasma can also be used for the treatment of many severe conditions.

For example

Proteins and antibodies present in the plasma are used in the treatment of hemophilia and autoimmune disorders.


plasma donation

As we mentioned above that plasma is used for the treatment of many severe conditions and saves the lives of many persons.

So if you want to help others by donating you will go through the following steps.

1.  First, you have to pass the screening test to make sure that your blood is healthy and safe.

2.  In the next step, your blood is drawn through a needle placed in a vein.

3.  In this step, plasma is separated from your blood sample through a special machine.
The separation of plasma from the blood is known as plasmapheresis.

4. In the last step, the remaining blood is returned to your body in a combination with a little saline solution.

The plasma of AB blood is universal which means that it can be used by anyone.


What are their functions?

As we know that our blood contains red blood cells, white blood cells, platelets, and plasma.

Plasma makes 55% of blood.

1.  Plasma removes waste from cellular functions.

2.  Plasma has the ability to absorb and release heat and thus maintains the body temperature.

3.  Plasma contains albumin which maintains a balance of fluid in the blood.

4.  Fibrinogen present in the plasma plays a major role in blood clotting and reduces active bleeding.

5.  Immunoglobulin present in the plasma helps the body to fight against infections.

Plasma cell neoplasms

These are diseases in which the body makes too many plasma cells.

These are of several types which are
Multiple myelomas

Symptoms of MGUS

In some cases, MGUS become a serious condition which are,

Problems with kidneys
Problems with heart
Problems with nerves

Chronic lymphocytic leukemia

Symptoms of plasmacytoma

Pain in bones
Broken bones
Hard to swallow

Symptoms of multiple myeloma

Pain in the ribs
Trouble in breathing
feeling tired.
