  2. Composition of Blood • Plasma • Red blood cells • White blood cells • Platelets • Lymph and interstitial fluid.

  3. Blood Donation: Separation Donated blood is extracted from a person and then stored until use can be approved. The main products of donated blood are: • Plasma • Red cell concentrate • Platelet concentrate • White cell concentrate Blood is a mixture which means that these substances have not chemically reacted to each other. Therefore the mixture can be centrifuged so that different substances form ‘levels’. Each substance has different properties which means they can be separated through methods such as decanting and filtration.

  4. Blood Donation Products The main blood products are: • Plasma- this is the liquid part of the blood and is transferred to a patient to increase the volume of blood in that person that may follow severe blood loss. • Red cell concentrate- This is concentrated red blood cells and is used to boost the ability to carry oxygen around the body. • Platelet concentrate- This helps to clot the blood in people that need that ability such as people with leukemia. • White cell concentrate- used to fight against infection. It is given to people who need the ability to fight infection such as a person who has had a sever infection in the past.

  5. Artificial blood Artificial blood is the extraction and purification of animal blood. It can be treated so that it does not contain disease and will therefore not cause a negative reaction in patients. It is able to be stored for years at a room temperature and not diminish in quality. This fake human blood has potential to be a great oxygen carrier in a human body.

  6. Need for artificial blood Artificial blood is needed because: • Donated blood does not have the ability to be conserved for an extended period of time and many countries lack the technology to sustain it for a minimal period of time. • Donated blood products are likely to be rejected by the recipient of the blood’s body which means allergic reactions or rejection reactions may occur. • Donated blood can also carry transmittable and deadly disease such as hepatitis or HIV which is be contracted by the recipient.
