Most carbohydrates in the human body are stored as glycogen in the liver and muscles, serving as a primary source of energy. Excess carbohydrates can also be converted to fat for long-term energy storage. Some carbohydrates are used immediately for energy or incorporated into cellular structures.
Personification.
The Gonads are generically the organs that produce gametes that is the testis in a man or an ovary in a woman. However, in the vernacular form the term is usually used to refer to the male's organs.
Generally they're not used, since animal organs are not similar to human organs, so are not suitable for maintaining function within the human body. In very rare circumstances they are used to try and bridge a gap until a human organ becomes available. They are never used as a long term solution (because they do not work long term). Whether they should be used or not is practically irrelevant, since they cannot be used as a long term solution.
Animal to human transplantation (or "xenotransplantation") is nowhere near as common as some people seem to believe. Generally animal organs are not used since animal organs are not similar to human organs and do not maintain function within the human body. In exceptionally rare circumstances they are used to try and bridge a gap of a few days, until a human organ becomes available. They are never used as a long term solution (because they do not work long term). In these cases, the organ is best "attached" outside the body of the recipient to avoid unnecessary side-effects from the non-human donor. Whether they should be used or not is practically irrelevant, since they cannot be used as a long term solution. Sometimes heart valves from pigs and cows are used in human transplantation, however these do not count as "organs", even if they do occur fairly frequently.
Sense organs are the organs used when human senses are used. These organs include eyes, ears, the tongue, the nose, and fingers.

People seem to assume that xenotransplants are far more common than they actually are. In very rare circumstances they are used to try and bridge a gap until a human organ becomes available.

A radioisotope can be used as a tracer in the human body because tracers are used in the imaging the body's organs and tissues.
If you mean a "xenotransplant", it is a transplant of animal organs to a human. These types of transplant are incredibly rare, since xenotransplantation just does not work long term - animal organs do not work in humans. (Sometimes xenotransplantation is used to bridge a gap for a very ill patient, until a human organ becomes available).
