Pancreas
Long, irregularly shaped gland, which lies behind the stomach, and secretes pancreatic juice into the lower end of the stomach that aids in the digestion of proteins, carbohydrates, and fats. The pancreas can be donated and transplanted. Also see Islet Cells Transplants.

Payment
Donor families are never responsible for costs related to donation.

PELD
Candidates under the age of 18 who are waiting for livers are placed in categories according to the Pediatric End-stage Liver Disease (PELD) scoring system. PELD is similar to MELD but uses some different criteria to recognize the specific growth and development of children. PELD scores may also range higher or lower than the range of MELD scores. The measures used are as follows: (1) Bilirubin, which measures how effectively the liver excretes the bile; (2) INR (prothrombin time), which measures the liver's ability to make blood clotting factors; and (3) Albumin, which measures the liver's ability to maintain nutrition; (4) growth failure; and (5) whether the child is less than one year old when listed for a transplant.

Perfusion
The passage of fluid through empty spaces to preserve the viability of recovered organs.

Peripheral Vascular Disease
Diseases of the extremities involving the arteries, veins and lymph nodes.

Procurement

R
Recipient
An individual who receives transplanted organs or tissues. Federal and State legislation requires hospitals to have in place written policies and protocols for referring potential organ and tissue donors and/or requesting donation from families of potential donors. Factors such as race, gender, and age income or celebrity status are not considered when determining who receives organs or tissues.

Recover
A term used to describe the process of recovering life-saving and life-enhancing organs and tissues for recipients on the waiting list. Donated organs are removed surgically; donation neither disfigures the body nor eliminates the possibility for an open casket funeral.

Registry
See New York State Organ and Tissue Donor Registry

Rejection
(1) The body's attempt to destroy the transplanted organ; usually occurs in the first year after transplant. (2) Rejection occurs when the body tries to attack a transplanted organ because it reacts to the organ or tissue as a foreign object and produces antibodies to destroy it. Anti-rejection (immunosuppressive) drugs help prevent rejection.

Required Request
Hospitals must tell the families of suitable donors that their loved one's organs and tissues can be used for transplant. It is hoped that this law will increase the number of donated organs and tissues for transplantation by giving more people the opportunity to donate.

Routine Referral
Hospitals are required on or before each death to call the Organ Procurement Organization (OPO) in order to determine suitability for organ, eye and tissue donation. The OPO, in consultation with the patient's attending physician or his or her designee, will determine the suitability for donation. If the patient is a candidate for anatomical donation, only personnel from the OPO or a designated requestor from the hospital can request donation from the next of kin.

S
Saphenous Vein
A blood vessel in the lower leg carrying blood toward the heart. The saphenous veins serve as the principal vessels running superficially (near the surface) up the leg.

Sclera
The white part of the eye.

Sclera Patches
These are used when the sclera (white part of the eye) has thinned or has been punctured. When the sclera breaks, vision is lost completely. A sclera patch restores the eye to its proper shape so that it may function normally.

Soft Tissues
Tissues that connect, support or surround other structures and organs of the body. These include muscle, fat, tendons, ligaments, cartilage, fibrous tissue, blood vessels, or other supporting tissues of the body.

Suitability Assessment
This is an evaluation, using existing information about a potential donor, to determine whether the donor meets specific qualifications for suitable transplantation.

T
Tendons
The transfer of organs and/or tissues to a recipient.

Thoracic Aorta
The thoracic aorta is a section of the aorta, the largest artery in the body, within the chest. Specifically, the thoracic aorta is that part of the aorta that starts after the arch of the aorta and runs down to the diaphragm, the great muscle that separates the chest from the abdomen. The thoracic aorta gives off numerous branches that supply oxygenated blood to the chest cage and the organs within the chest.

Tissue Bank
An organization that provides or engages in one or more services involving cells and/or tissue from living or deceased individuals for human transplantation purposes. Click here for details.

Tissue Recovery Staff
Specially trained New York Organ Donor Network technicians that perform tissue recovery under sterile conditions.

Tissues
Tissues available for transplantation include corneas, skin, bone, heart valves, veins and tendons. Click here for details.

Transplant Center
A hospital that performs transplant surgery. Click here for details.

Transplant Coordinator
A nurse who helps facilitate transplantation with both donor families and recipients. Engages in donor management with hospital personnel. Coordinates the acquisition and placement of organs and tissues.

Transplantation
A surgical procedure whereby life-saving and life-enhancing organs and tissues are implanted into a living human recipient. Click here for details.

U
Uniform Anatomical Gift Act
A model set of laws, adopted by many states, regarding a person's gift of his or her body parts after death. Legislation that provides guidelines for the voluntary donation of organs and tissues. The law outlines authorization for making this gift, describes the manner in which it may be done, and prohibits the sale of organs and tissues for profit. Click here for details.

United Network for Organ Sharing
The transplant community is joined under a nationwide umbrella: The United Network for Organ Sharing (UNOS), a nonprofit charitable organization, administers and maintains the nation's organ transplant waiting list under contract with the Health Resources and Services Administration of the U.S. Department of Health and Human Services. Located in Richmond, Virginia, UNOS brings together, under that contract and on behalf of the Organ Procurement and Transplantation Network (OPTN), medical professionals, transplant recipients and donor families to develop organ transplantation policy. The U.S. Organ Procurement and Transplantation Network (OPTN) helps ensure the success and efficiency of the U.S. organ transplant system. Click here for more details.
