This transplant is used in emphysema (fibrosis of alveolar sacs), hereditary lung blockages, chronic infections and thickening of lung tissue, reducing its capacity. 80% of patients survive 1 year after being transplanted, and 60% remained alive for a period of 4 years. 
Heart: The heart pumps blood throughout our body, so that oxygen gets picked up in the lungs. Transplantation is indicated when there is severe disease of the coronary arteries (those supplying the heart), and severe heart valve disease or congenital impairment. If the rejection of the tissue is adequately controlled with medication and care, the patient may live 10 years.
Liver: summarizes different proteins, and detoxifies the body of substances coming through the intestines.

Blood: is also a tissue, but liquid. Allows oxygen transport, defense against infections, among other functions. It is mainly used in patients with anemia (to improve oxygen transport), and to stop or prevent bleeding. You can donate every 3 months to 65 years.
