Most often, organ donors are deceased, but some organs can be donated by living donors.
Deceased organ donors can donate: kidneys (2), liver, lungs (2), heart, pancreas, and intestines. In 2014, hands and faces were added to the organ transplant list.
Living organ donors can donate: one kidney, a lung, or a portion of the liver, pancreas, or intestine.
By registering as a cornea donor, you can also leave behind the gift of sight. Here are some facts about cornea and eye donation:
Donated tissues save or dramatically improve the quality of life for the people who receive them. As an organ and tissue donor, you can enhance the lives of up to 50 people.
Corneas, the middle ear, skin, heart valves, bone, veins, cartilage, tendons, and ligaments can be stored in tissue banks and used to restore sight, cover burns, repair hearts, replace veins, and mend damaged connective tissue and cartilage in recipients.
Heart valves can be transplanted to save the lives of children born with heart defects, and adults with damaged heart valves.
Skin can be used as a natural dressing for people with serious burns. It can even save lives by stopping infections.
Bone is important for people receiving artificial joint replacements, or replacing bone that has been removed due to illness or injury, for example in hand and face transplants.
Tendons, the elastic-like cords that attach bones and muscles to each other, can be donated to help rebuild damaged joints.
Most people can be tissue donors when they die. The local tissue bank (a tissue recovery organization) will be notified by the hospital, medical examiner or funeral home.
Tissue donation must be initiated within 24 hours of death. However, tissue can be processed and stored for an extended period of time.
Each year, about 30,000 donors provide lifesaving and life-enhancing tissue.
Hands and faces have recently been added to the list of organs that can be successfully transplanted.
These complicated surgeries are technically called vascularized composite allografts (VCAs) because they are surgeries composed of grafting many kinds of tissue: bone, muscle, nerves, skin, and blood vessels.
In 2005, the first hand transplants were performed, and in 2007, the first face transplant was performed. Developments in immunosuppressive drugs help to keep these and all transplants from being rejected.
Fewer than 125 hand and face transplants have been performed worldwide. But for the people who now have hands to use or a face to show the world, VCA transplants are transforming lives.

Healthy adults between the ages of 18 - 60 can donate blood stem cells. In order for a blood stem cell transplant to be successful, the patient and the blood stem cell donor must have a closely matched tissue type or human leukocyte antigen (HLA).
Since tissue types are inherited, patients are more likely to find a matched donor within their own family or racial/ethnic group. There are three sources of blood stem cells that healthy volunteers can donate:
Bone marrow: This soft tissue is found in the interior cavities of bones. It is a major site of blood cell production and is removed to obtain stem cells.
Cord blood stem cells: The umbilical cord that connected a newborn to the mother during pregnancy contains blood that has been shown to contain high levels of blood stem cells. Cord blood can be collected and stored in large freezers for a long period of time and, therefore, offers another source of stem cells available for transplanting into patients.
Peripheral blood stem cells: The same types of stem cells found in marrow can be pushed out into a donor's bloodstream after the donor receives daily injections of a medication called filgrastim. This medication increases the number of stem cells circulating in the blood and provides a source of donor stem cells that can be collected in a way that is similar to blood donation.
If you are interested in donating blood stem cells, contact a donation organization.
Blood and platelets are formed by the body, go through a life cycle, and are continuously replaced throughout life. This means that you can donate blood and platelets more than once. It is safe to donate blood every 56 days and platelets every four weeks.
Blood is stored in a blood bank according to type (A, B, AB, or O) and Rh factor (positive or negative). Blood can be used whole, or separated into packed red cells, plasma, and platelets, all of which have different lifesaving uses. It takes only about 10 minutes to collect a unit (one pint) of blood, although with the testing and screening, the process of donating blood takes about an hour.
Platelets are tiny cell fragments that circulate throughout the blood and aid in blood clotting. Platelets can be donated without donating blood. When a specific patient needs platelets, but does not need blood, a matching donor is found and platelets are separated from the rest of the blood which is returned to the donor. The donor's body will replace the missing platelets within a few hours.
