Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.
Red blood cells deliver oxygen from your lungs to your tissues and organs. White blood cells fight infection and are part of your body's defense system. Platelets help blood to clot when you have a cut or wound. Bone marrow, the spongy material inside your bones, makes new blood cells. Blood cells constantly die and your body makes new ones. Red blood cells live about 120 days, platelets 6 days and white cells less than a day.
Problems with your blood include bleeding disorders and platelet disorders. If you lose too much blood, you may need a transfusion.

Bleeding is the loss of blood. It can happen inside or outside the body. Bleeding can be a reaction to a cut or other wound. It can also result from an injury to internal organs.
There are many situations in which you might bleed. A bruise is bleeding under the skin. Some strokes are caused by bleeding in the brain. Other bleeding, such as gastrointestinal bleeding, coughing up blood, or vaginal bleeding, can be a symptom of a disease.
Normally, when you bleed, your blood forms clots to stop the bleeding. Severe bleeding may require first aid or a trip to the emergency room. If you have a bleeding disorder, your blood does not form clots normally.
