People with blood types O characteristically have no antigens A and B present but have antibodies for A and B. Due to this characteristic feature of their blood types, they are capable of donating blood to people with any blood type, hence they're considered to be universl donors; however they can only receive blood from people with the same blood type as theirs. For example, blood type O+ can get blood from Type O+ or O-. Since blood type O is relatively common, it is therefore easy to get blood quickly when needed and hospitals tend to have this blood type in stock due to universal donor feature.
The most common type of blood is O positive. This type of blood is known as the universal donor because neither A nor B antigens are found on the surface of the red blood cells and this type of blood therefore can be given to an individual with any blood type in need of transfusion.
Some are, but urine samples are more common.
Because you need blood
we need airplane because people had to travel from pace to place quickly!
Because you need to do so to survive. Without blood circulating through the lungs, it would not be able to distribute oxygen to areas like muscle groups or the brain, and the body would quickly die.
The most common blood type in Europe is O positive. This impacts blood donation efforts because O positive blood can be transfused to patients with other blood types, making it in high demand for emergency situations. However, it also means that there is a greater need for donors with other blood types to ensure a sufficient supply for all patients.
wot sort of a question is that??? and y wood u need 2 no anyway???
Only 10% because you need blood to be alive and to breath correctly and you need blood to flow through you veins and arteries
Because iron is the component of haemoglobin and by giving it, it increase blood formation rapidly which give more power quickly.

donating blood is important because everyday people of all ages are put in the hospital in need of blood and the people who donate blood are life savers because people who need blood can die but they get blood from the blood drive and they live a full happy and healthy life.
They're travelling in their vehicle because they need to get there quickly.
