Plasma is the liquid part of blood that ensures that the blood cells can flow throughout the body. It is a yellow straw colored liquid in which the blood cells are normally suspended. Plasma makes up around 55% of the total volume of blood in the human body. The rest of the blood is a combination of red and white blood cells (there are approximately700 red blood cells per white blood cell).

Plasma also serves as a transport system, delivering various materials between the cells. 92% of plasma consists of water, but it also contains other components such as salts, proteins, lipids and glucose.

Plasma also transports harmful materials, such as urea to the kidneys.
The composition of blood, according to eHow.com, is:

- 92% water
- 6-8% proteins
- 0.8% salts
- 0.6% lipids
- 0.1% glucose (blood sugar)

Plasma plays a central role in retrieving the materials that are necessary for the body's survival. It retrieves material from such organs as the liver and the small intestine. These materials are then delivered to the cells. The materials tend to be the results of digestion and include:

- amino acids
- mineral salts
- vitamins
- glucose
- hormones
- lipids
- ions

In addition to transporting materials, plasma also plays an important role in the body's defence. Plasma contains antibodies, anti-toxins and fibrin, which is a clotting agent that works with the platelets to help heal wounds.

Plasma is the fluid matrix in which red blood cells and white blood cells are suspended into. Plasma is made of inorganic salts, proteins (immunoglobulins, albumins, fibrinogens), nutrients, metabolic waste products, and respiratory gases. Plasmas main functions are to act as buffers, maintain osmotic balance and to contribute to viscosity of blood.

The bloods Plasma is needed because without it nothing would flow. Red
Blood Cells are very large and trying to pump them through air (ie if
there was not plasma) would be impossible. Not to mention the fact that
more than just oxygen is carried by the blood, there is also Nutrients
(like Glucose) and proteins, all of which must be dissolved to move
around. Without plasma there would be not flow and all the cells of the
body would die.

All of the blood cells in your body are mixed together in a slightly yellowish liquid called Plasma. Plasma is mostly made up of water, but also contains proteins, sugars and salt. In addition to carrying blood cells throughout the body, plasma also carries hormones, nutrients and chemicals, such as iron.Plasma has the important function of maintaining the pH of the blood at approximately 7.4 Thus thats plasma

Plasma is actually the medium in which all the chemical reactions vital for our body takes place along with the certain cell activities
Plasma mainly consist of WBC ( white blood cells) which helps in healing the wounds, in spite of that they are anti bacterial and helps the body to resist certain viruses and bacterias. Blood is a soft connective tissue  and so is composed by complex structures

Wow! That's a big question.
Plasma contains, among other things, the clotting agents.  When you get a wound, these agents aid in healing and stopping the bleeding.
Plasma also contains proteins that help carry insoluble materials to/from cells as needed.
Plasma also contains antibodies (gammaglobulins) to help resist/fight off infections.
This is really just the tip of the iceberg though.  There are whole chapters and books written on the role of plasma!

I don't think that books are written on the roles of plasma!

I thought it was platelets which clot the blood to stop bleeding?And plasma is the one which produce antibodies?

Plasma is basically just the liquid part of the blood. Its what all the blood cells and other components of the blood are suspended in, and where all the chemical reactions take place. The blood plasma is what really acts as the transport system of the body, allowing oxygen and nutrients from food to be transported to all the cells of the body. Without the blood plasma the blood wouldn't be blood really, it would just be loads of different cells.

To Roosmom143 I think you have platelets and plasma mixed up. The function of plasme is to keep the blood a liquid and flowing

Plasma does not contain white blood cell or platelet (clotting). They are called the formed elements. Blood is made up of formed elements and plasma. Plasma contains mostly water (91.5 %) and solutes (proteins).
