It must be known that there is an interdependent relationship between meiosis and sexual reproduction. During sexual reproduction, meiosis generates a genetic variation in the offspring because it randomly shuffles genes across chromosomes and then randomly segregates half of those chromosomes into each gametes. These two gametes or sex cells then fuse randomly to form a new organism. One of the key factors in evolutionary fitness and biological diversity is genetic variation. This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation.
To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.
Reproductive organs of both men and women are vital to create a child. But it must be noted that both can live without them. There are situations that sometimes necessitates the removal of such organs especially if he or she is inflicted with cancer or other diseases.

Answer:
Blood taken from an artery in the leg is oxygenated while blood taken from a vein in the leg is deoxygenated.
Vibrissae, more commonly known as whiskers, are sensory hair
that generally have a tactile sense, which is equivalent to skin. They grow on
most mammals except monotremes (duck-billed platypus and echidnas) and humans,
though humans still have remnants of the muscles once associated with vibrissae
in their upper lips. Vibrissae serve a number of purposes: such as sense of
touch; detection of danger, air and water currents, and movements of other
animals; and the locating of food.
