what are the two types of organ donors
Organ transplantation Organ donors may be living, brain dead, or dead via circulatory death.[1] Tissue may be recovered from donors who die of circulatory death, as well as of brain death â€“ up to 24 hours past the cessation of heartbeat. Unlike organs, most tissues (with the exception of corneas) can be preserved and stored for up to five years, meaning they can be "banked". Transplantation raises a number of bioethical issues, including the definition of death, when and how consent should be given for an organ to be transplanted, and payment for organs for transplantation.[2][3] Other ethical issues include transplantation tourism and more broadly the socio-economic context in which organ procurement or transplantation may occur. A particular problem is organ trafficking.[4]
Organ (anatomy) The study of plant organs is referred to as plant morphology, rather than anatomy, as in animal systems. Organs of plants can be divided into vegetative and reproductive. Vegetative plant organs are roots, stems, and leaves. The reproductive organs are variable. In flowering plants, they are represented by the flower, seed and fruit. In conifers, the organ that bears the reproductive structures is called a cone. In other divisions (phyla) of plants, the reproductive organs are called strobili, in Lycopodiophyta, or simply gametophores in mosses.
