The blood of peanut worms contains haemerythrin which turns violet-pink when oxygenated. White blood cells are mainly responsible for defending the body against infection. And platelets are small cell fragments which help your blood to clot by clumping together at the place of bleeding.
A red cell in a vein on its own is a bit like a kid on a waterslide without water. How do you say that? Lots of things. Plasma is mainly made up of water around 92 per cent , helping to maintain our circulation: it fills up our blood vessels by flowing continuously—without it, a blood vessel would just collapse like a sad, floppy hose. Plasma also helps remove waste products from the body, by transporting them to the liver or kidneys, for example.
And it carries heat from core tissues to other areas of the body like our hands and feet, helping us maintain our body temperature. Albumin is the most abundant of these. Then there are globulins, of which there are three main kinds: alpha, beta and gamma. Alpha and beta globulins are made in the liver. Their functions include transporting various compounds around the body.
During an immune response, they help defend it against invaders such as viruses and bacteria. These defender proteins are also known as immunoglobulins, or antibodies. Fibrinogen proteins, also made in the liver, control bleeding by forming blood clots. The product which Hayley receives via her monthly transfusion, for example, is made from plasma. The shortfall has to be imported from overseas. There are a couple of different ways you can donate plasma. The first is to donate whole blood red cells, white cells, plasma and platelets , which is then separated out so that the different components, including the plasma, can be used to treat specific medical conditions.
The second is to donate just plasma via a process known as plasmapheresis. This is where a machine takes your plasma and sends the rest of your blood back to your body. The process goes something like this. A needle is put into your arm with a tube running from it into the plasmapheresis machine. A pump then draws the blood from your arm into a blood-separating kit in the machine. A small amount of anticoagulant is added to stop the blood from clumping together in the machine.
Inside the machine, your blood goes into a centrifuge where it gets spun around at high speeds. This separates the blood into layers: because plasma is lighter it ends up on the top layer, while the heavier red cells sink to the bottom.
The machine is programmed to recognise the plasma, sending it into a special collection bag. Every so often the red cells are flushed back into your arm. The whole cycle is repeated again, and again, until the desired amount of plasma depending on your weight, height, and so on has been obtained.
People in emergency situations can receive this type of plasma immediately, which could mean the difference between life and death.
People with this blood type can do this every 28 days , or up to 13 times a year. Click here to learn more about donating plasma. Plasma is the yellow-colored, liquid component that makes up most of the blood. It helps with immunity, blood clotting, maintaining blood pressure, blood volume, and pH balance in the body. It also plays a key role in transporting blood cells, nutrients, proteins, waste products, and hormones throughout the body. People who are capable of donating blood may want to consider donating plasma.
It is in high demand as it can be very useful for treating people with massive blood loss, liver failure, cancer, rare diseases, or other health issues. Alternatively, people can find a donation drive through the American Red Cross. Who can donate blood?

Medically reviewed by Deborah Weatherspoon, Ph. The proteins and antibodies in plasma are also used in therapies for rare chronic conditions. These include autoimmune disorders and hemophilia. People with these conditions can live long and productive lives because of the treatments.
In fact, some health organizations call plasma "the gift of life. If you want to donate plasma to help others in need, you will go through a screening process. This is to make sure your blood is healthy and safe.
If you qualify as a plasma donor, you'll spend about an hour and a half at a clinic on every follow-up visit. During the actual blood donation process, your blood is drawn through a needle placed in a vein in one arm. A special machine separates the plasma and often the platelets from your blood sample. This process is called plasmapheresis. The remaining red blood cells and other blood components are then returned to your body, along with a little saline salt solution.
Type AB plasma can be given to people of all blood types.
